Hudson Massachusetts Concrete Cutting and Core Drilling

A Standard Mixture for reinforced floors, beams and columns, for arches, for reinforced engine or machine foundations subject to vibrations, for tanks, sewers, conduits and other, water-tight work: Proportions�i :2 :4; that is, one barrel (4 bags) packed Portland cement to two barrels (7.6 cubic feet) loose sand to four barrels (15.2 cubic feet) loose gravel or broken stone. A Medium Mixture for ordinary machine foundations, retaining walls, abutments, piers, thin foundation walls, building walls, ordinary floors, sidewalks and sewers with heavy walls: One barrel (4 bags) packed Portland cement to two and one-half barrels loose sand to five barrels (19 cubic feet) loose gravel or broken stone. A Lean Mixture for unimportant work in masses, for heavy walls, for large foundations supporting a stationary load and for backing for stone masonry: Proportions�i 3 :6; that is, one barrel (4 bags) packed Portland cement to three barrels (11.4 cubic feet) loose sand to six barrels (22.8 cubic feet) loose gravel or broken stone. Green timber is preferable, for, if seasoned, it is likely to FORMS swell and warp when brought in contact with moisture from the concrete. White pine is best, but fir, yellow pine or spruce is also suitable.

If a smooth surface is desired, the form boards or planks next to the concrete must be planed and the edges tongued and grooved or beveled. Grease the inside of forms with either soap, linseed oil, mixed lard and kerosene, or crude oil, that is, petroleum, otherwise particles of concrete will stick to the forms when they are removed, thus giving an unnecessarily rough surface to the face of the concrete should not be greased when it is intended to plaster the surface of the concrete, but should be thoroughly wet immediately before placing the concrete. Lay the sheathing or form boards horizontally. These may be of i-inch, i3/2-inch or 2-inch lumber, the distance apart of the studding being governed by the thickness of sheathing selected. Place the studs not more than 2 feet apart for i-inch sheathing, nor more than 5 feet apart for 2-inch sheathing. They should be securely braced to withstand the pressure of the soft concrete, also of the ramming and tamping. In building forms do not drive the nails all the way home. Leave the heads out so that it is possible to draw them with a claw hammer. The least amount of hammering done around green concrete is better. Avoid cracks in forms into which the mortar will force itself and form the surface of the work. The length of time the forms should be left in place varies with conditions. Where no pressure is brought to bear on the concrete, forms can be removed within one-half to two days, or as soon as the concrete will withstand the pressure of the thumb without indentation. On very small work, like drain tile, two to four hours is sufficient time, provided it is carefully handled and left in place until thoroughly hard.

On large and important walls one to three days are generally required, and if any water or earth pressure comes against the walls the forms should be left in place from three to four weeks. Slab forms can be removed in about one week, but the supporting posts under any beams and slabs must not be touched for a month after laying the concrete. Concrete forms are kept from separating or bulging either by using bolts or by wiring. Bolts as a general rule are more satisfactory on large work than wire, but as they cannot always be conveniently obtained, wires are used extensively. In Fig. 3 are sketched both methods for holding side forms together. The spacers are only placed between the forms to hold them the proper distance apart, and must be removed after some of the concrete is placed. Where wires are used, the forms are drawn together by twisting, as shown in the figure.
