Properties of Concrete Blocks — Strength

Actual tests of compression strength of hollow concrete blocks are difficult to make because it is almost impossible to apply the load uniformly over the whole surface and also because a block 16 inches long and 8 inches wide will bear a load of 150 000 to 200 000 pounds or more than the capacity of any but the largest testing machines Three one-quarter blocks 8 inches long 8 inches wide

Core testing for strength

Before testing cores for strength they have to be trimmed to length and the ends prepared so that they are flat and perpendicular to the longitudinal axis This is achieved by grinding or more usually capping with high alumina cement (calcium aluminate cement) mortar or a sulphur/sand mixture Cores should be tested in a dry state This is a air dry not oven dry If tested wet a small positive correction to the
