Are You in Lexington Massachusetts? Do You Need Concrete Cutting?
Consistency of concrete should be like heavy cream. The cost of concrete work varies considerably on account of the many elements entering into the work. For instance, the cost of building the various structures illustrated in this book may be very small, as the work itself may be done by the owner or farmer at odd times or with comparatively cheap help, while in building with other materials, either brick or - wood, it is necessary to employ carpenters or masons. Moreover, even if the lumber for the forms costs nearly as much as the lumber for a wooden structure, as is sometimes the case, it need not be thrown away, but may be used again for other purposes. If hired laborers and carpenters do the work it may be stated as a general rule that concrete is always more expensive in first cost than wood. On the other hand, concrete does not rot, it does not burn, and it does not have to be painted, so that it frequently may be cheaper in the long run. Besides this, more unique and pleasing effects may be produced.
Concrete is one of the best fireproof materials known. It resists intense heat better than iron, steel, ordinary brick or stone, and in the San Francisco and Baltimore fires it stood the test better than any other material. It can therefore be depended upon to resist any ordinary fire. Concrete is used extensively as a fire-protective covering for steel, for which purpose about two inches is necessary. In reinforced concrete the iron or steel should be imbedded one or two inches for protection. By mixing wet and using proportions one part Portland Cement to one and one- half parts sand to three parts screened gravel and placing in one continuous operation, so that no surface is allowed to harden, or else by forming very good joints as described on page 116, concrete is watertight under ordinary conditions. Long walls to resist water pressure must be well reinforced to prevent cracks due to temperature contraction, since concrete expands and contracts with changes of temperature just like other materials.
Concrete properly proportioned and mixed wet absolutely prevents any metal imbedded in it from rusting. Concrete resists sea water, provided it is properly proportioned with first-class materials and is carefully laid. After concrete has thoroughly hardened it resists acids better than almost any other material. A substance like manure, because of the acid which it contains, has been known to slightly injure the surface of green concrete, but after the concrete has hardened for at least a week it is proof against injury. When concrete is properly made and the surface carefully finished and is hardened before the oil comes against the concrete, it can be depended upon to resist the action of almost any oil. For use in the regions where there is alkaline ground water, concrete should be especially rich, dense and water-tight. Concrete work should be avoided so far as possible in freezing weather, as the frost will prevent the bonding of different layers and will cause a thin scale to peel off of the surface of concrete.
It is a good rule to follow, therefore, never to lay concrete. if the temperature is below freezing or liable to fall below freezing in a day or two. The use of concrete fence posts is becoming very general. This is due not only to the scarcity and high price of good straight wood posts, but to the almost unlimited life of the concrete post, its greater strength and more pleasing appearance. Concrete fence posts should be a little larger than wood fence posts, and may be made either straight for the whole length or slightly tapering. Five or six inches square at the bottom and four or five inches square at the top is an ordinary size, or for convenience in molding they may not be made exactly square, say, 6 inches by5 inches at the bottom and 5 inches by 4 inches at the top, this size being selected for the form shown.
