CIP 16 - Flexural Strength Concrete WHAT is Flexural Strength? Flexural strength is one measure of the tensile strength of concrete It is a measure of an unreinforced con-crete beam or slab to resist failure in bending It is measured by loading 6 x 6-inch (150 x 150-mm) con-crete beams with a span length at least three times the depth

The reuse of crushed waste ceramic tiles as a substitute for fine aggregate in concrete has been investigated in this study Waste ceramic tiles obtained from building demolition sites and left-overs from new building sites were used The crushed waste ceramic tiles were substituted in place of fine aggregates in the following percentages (0% 20% 25% 30% 35% and 40%) in the concrete mix

Concrete strength Many factors influence the rate at which the strength of concrete increases after mixing Some of these are discussed below First though a couple of definitions may be useful The processes of 'setting' and 'hardening' are often confused Setting is the stiffening of the concrete after it has been placed A concrete can be 'set' in that it is no longer fluid but it may
