Answer to #1

The dimensions of standard cinder block are 7 5/8 in high and 15 5/8 in. long when they are laid with a
3/8-in. mortar joint.



Answer to #2

Reinforced 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 #3

Sidewalks need shallow grooves or joints across the surface at three-foot intervals to control cracking
due to expansion.



Answer to #4

A construction joint is a place where one pouring of concrete stops and another begins. A control joint
is a planned break that permits concrete to expand and contract without cracking. Control joints are
placed at equally spaced intervals in the slab.



Answer to #5

The formula for determining the cubic feet of concrete is obtained by multiplying the thickness (T) of
the 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.
