Wonderful Holiday Amidst Splendid Nature, Culture And History In Waltham Massachusetts
Waltham is a large city in the Middlesex County, of US, and its early hub for a major contributor as well as the labor movement to the American Industrial revolt. The original place of the Boston manufacturing management, The Waltham is now a hub for and higher education research, home to Bentley University and Brandeis University. The population was about 60,636 at the time of the 2010 census.
Waltham is administrated by a city council and a mayor. the present mayor is Jeanette A. McCarthy. There’re around 15 representatives of city council, each selected with a two year of term in non-partisan elections. The present president of the place is Robert J. Waddick.
The Waltham is in Massachusetts's fifth congressional region and is presently representative in US house of members by Katherine Clark. The city is even represented in Massachusetts House of Members by the State Representative John J. Lawn and Thomas M. Stanley in Massachusetts Senate by the Senator Michael Barrett.
The Charles river passes via walking, bike and Waltham paths and cover most of the southern band as well as a part of north bank from the Prospect Street - Moody Street. Some passenger ride the way to workplaces in Boston and Cambridge.
Waltham is house to the Waltham News Tribune, formerly known as The Daily News Tribune, a weekly paper that publishes each Friday, as well as year-round. WCAC-TV offers local-interest TV programming. Waltham news sometimes comes in The Boston Worlds GlobeWest part, as well. The radio station 99.5 that specializes in classical music has workplaces in Waltham on the South Street.

A reinforced concrete water-tank, 10 feet inside diameter and 43 feet high, designed and constructed by W. B. Fuller at Little Falls, N. J. has some remarkable features. It is 15 inches thick at the bottom and 10 inches thick at the top. We used Apple’s Final Cut Pro software to produce our concrete cutting video. The concrete tank was built in eight hours, and is a perfect monolith, all concrete being dropped from the top, or 43 feet at the beginning of the work. The concrete was mixed very wet, the mixture being 1 part cement, 3 parts sand, and 7 parts broken stone. No plastering or waterproofing of any kind was used, but the tank was found to be absolutely water-tight although the mixture used has not generally been found or considered water-tight. A large reinforced concrete structure, 50 feet in diameter, 106 feet high from the inside of the bottom to the top of the cornice, and with a capacity of 1,500,000 gallons, has been constructed, and is in the service of the water works of that city.
The concrete walls of the standpipe are 18 inches thick at the bottom, and 8 inches thick at the top. A mixture of 1 part cement, 2 parts sand, and 4 parts broken stone, the stone varying from inch to 1 inch, was used. We perform concrete cutting in Waltham, Massachusetts. We have seen many a pro. Cut and core drilling services are available. The concrete forms were constructed, and the concrete placed, in sections of 7 feet. When the walls of the tank had been completed, there was some leakage at the bottom with a head of water of 100 feet. The inside walls were then thoroughly cleaned and picked and four coats of plaster applied. The first coat contained 2 percent of lime to 1 part of cement and 1 part of sand; the remaining coats were composed of 1 part sand to 1 part cement. Each coat was floated until a hard, dense surface was produced; then it was scratched to receive the succeeding coat. On filling the standpipe after the four coats of plaster had been applied, the standpipe was found to be not absolutely water-tight. The water was drawn out; and four coats of a solution of castile soap, and one of alum, were applied alternately; and, under a 100-foot head, only a few leaks then appeared. Practically no leakage occurred at the joints; but in several instances a mixture somewhat wetter than usual was used, with the result that the spading and ramming served to drive the stone to the bottom of the batch being placed, and, as a consequence, in these places porous spots occurred. The joints were obtained by inserting beveled tonguing pieces, and by thoroughly washing the joint and covering it with a layer of thin grout before placing additional concrete. In the construction of the filter plant at Lancaster, Pa., in 1905, a pure-water basin and several circular tanks were constructed of reinforced concrete.
The pure-water basin is 100 feet wide by 200 feet long and 14 feet deep, with buttresses spaced 12 feet 6 inches center to center. The walls at the bottom are 15 inches thick and 12 inches thick at the top. Four circular tanks are 50 feet in diameter and 10 feet high, and eight tanks are 10 feet in diameter and 10 feet high. The walls are 10 inches thick at the bottom, and 6 inches at the top. A wet mixture of 1 part cement, 3 parts sand, and 5 parts stone, was used. No waterproofing material was used, in the construction of the tanks; and when tested, two of them were found to be water-tight, and the other two had a few leaks where wires which had been used to hold the forms together had pulled out when the forms were taken down. These holes were stopped up and no further trouble was experienced. In constructing the floor of the pure-water basin, a thin layer of asphalt was used, as shown in Fig. 10; but no waterproofing material was used in the walls, and both were found to be water-tight.

The alternate application of washes of castile soap and alum, each being dissolved in water, is known as the Sylvester process of waterproofing. Castile soap is dissolved in water, of a pound of soap in a gallon of water, and applied boiling hot to the concrete surface with a flat brush, care being taken not to form froth. A circular template swung around a point which may be considered as a pole, may be used for making spherical surfaces, although such work is -now usually done in lathe instead of by hand. To make a warped surface or helicoidally surface, a template must be made, as in Fig. 34, by first cutting two drafts which shall fit a template made as shown in the figure. After these two drafts are cut, the surface between them is dressed down to fit a straight edge, which is moved along the two drafts and perpendicular to them. Such stonework is very unusual, and almost its only application is in the making of oblique or helicoidally arches.
The size of the concrete blocks has a very great influence on the cost of dressing the stones per cubic yard of concrete masonry. For example, to quote a very simple case, a stone 3 feet long, 2 feet wide, and 18 inches high has 12 square feet of bed-joints, 6 square feet of end joints, and 4.5 square feet of facing, and contains 9 cubic feet of concrete masonry. If the stones are 18 inches long, 1 foot wide, and 9 inches high (just one-half of each dimension), the area of each kind of dressed joint is one-fourth that in the case of the larger stones, but the volume of the concrete masonry is only one-eighth. In other words, for stones of similar shape, increasing the size increases the area of dressing in proportion to the square of the dimensions, but it also increases the volume in proportion to the cube of the dimensions. Therefore large stones are far more economical than small stones, so far as the cost of dressing is -a factor. The size of stones, the thickness of courses, and the type of concrete masonry should depend largely on the product of the quarry to be utilized. An un-stratified stone like granite must have all faces of the stone plug-and-feathered; and therefore the larger the stone, the less will be the area to be dressed per cubic foot or yard of concrete masonry. On the other hand, the size of concrete blocks which can be broken out from a quarry of stratified rock, such as sandstone or limestone, is usually fixed somewhat definitely by the character of the quarry itself.
The stratification reduces vary greatly the work required, especially on the bed-joints. But since the stratification varies, even in any one quarry, it is generally most economical to use a stratified stone for random concrete masonry, while granite can be cut for coursed concrete masonry at practically the same expense as for stones of variable thickness. Although, as explained above, the cost of dressing stone should properly be estimated by the square foot of surface dressed, most figures which are obtainable give the cost per cubic yard of concrete masonry, which practically means that the figures are applicable only to stones of the average size used in that work. A few figures are here quoted from Gillette's "Handbook of Cost Data:" Constructive Features—Bonding. It is a fundamental principle of concrete masonry construction, that vertical joints (either longitudinal or lateral) should not be continuous for any great distance. Concrete masonry concrete walls (except those of concrete blocks) are seldom or never constructed entirely of single concrete blocks which extend clear through the concrete wall. The concrete wall is essentially a double concrete wall which is frequently connected by headers. These break up the continuity of the longitudinal vertical joints. Concrete cutting is the process of controlled sawing in a systematic method. The continuity of the lateral vertical joints is broken up by placing the stones of an upper course over the joints in the course below. Since the headers are made of the same quality of stone (or brick) as the face concrete masonry, while the backing is of comparatively inferior quality, it costs more to put in numerous headers, although strength is sacrificed by neglect to do so. For the best work, stretchers and headers should alternate. We service Waltham MA with concrete sawing and coring. This would usually mean that about one-third of the face area would consist of headers. One-fourth or one-fifth is a more usual ratio. Cramps and dowels are merely devices to obtain a more efficient bonding. An inspector must guard against the use of blind headers, which are short concrete blocks of stone (or brick), which have the same external appearance on the finished concrete wall, but which furnish no bond.
After an upper course has been laid, it is almost impossible to detect them. For the same reasons given when discussing the relation of size of stones to amount of dressing required, more mortar per cubic yard of concrete masonry is needed for small stones than for large. The larger and rougher joints, of course, require more mortar per cubic yard of concrete masonry. In the tabular form at top of page 95, are given figures which, for the above reasons, are necessarily approximate; the larger amounts of mortar represent the requirements for the smaller sizes of stone, and vice versa. The stones should be very thoroughly wetted before lying in the concrete wall, so that they will not absorb the water in the mortar and ruin it before it can set. It is very important that the bed-joints should be thoroughly flushed with mortar. All vertical joints should likewise be tightly filled with mortar. In estimating such quantities, the following considerations must be kept in mind: (a) the accuracy of the dressing of the stone, particularly the bed- joints, has a very great influence. (b) The strength is largely dependent on that of the mortar. (c) The strength is so little dependent on that of the stone itself that the strength of the stone cannot be considered a guide to the strength of the concrete masonry. For example, concrete masonry has been known to fail under a load not brick concrete masonry, and therefore will not be here repeated. The following sections will be devoted to those terms and specifications which are applicable only to brick concrete masonry.
Some of the principles involved in the effect of bonding on the strength of a concrete wall, have already been discussed under "Stone Concrete masonry." The other consideration is that of architectural appearance. The common method of bonding is to lay five or six courses of brick entirely as stretchers, and then a course of brick will be laid entirely as headers. There is probably some economy in the work required of a bricklayer in following this policy. The so-called English Bond consists of alternate courses of headers and stretchers. If the face bricks are of better quality than those used in the backing of the concrete wall, this system means that one-half the face area of the concrete wall consists of headers; which is certainly not an economical way of using the facing brick.
