 Answer to #1The dimensions of standard cinder block are 7 5/8 in high and 15 5/8 in. long when they are laid with a3/8-in. mortar joint.Answer to #2Reinforced concrete refers to concrete slabs strengthened by using steel reinforcing rods or wire mesh.For example, cement that will carry vehicles or machinery must be reinforced.Answer to #3Sidewalks need shallow grooves or joints across the surface at three-foot intervals to control crackingdue to expansion.Answer to #4A construction joint is a place where one pouring of concrete stops and another begins. A control jointis a planned break that permits concrete to expand and contract without cracking. Control joints areplaced at equally spaced intervals in the slab.Answer to #5The formula for determining the cubic feet of concrete is obtained by multiplying the thickness (T) ofthe floor by its width (W) and length (L) in feet or Cu Ft = T  W  L. Then to obtain the cubic yards,the number of cubic feet is divided by 27, because one cubic yard contains 27 cubic feet.
