Concrete is a composite material composed of coarse aggregate bonded
together with a fluid .... Reinforcement is often included in concrete. Concrete can
be formulated with high compressive strength...
High Strength Concrete In the early 1970s, experts predicted that the practical
limit of ready-mixed concrete would be unlikely to exceed a compressive strength
The compressive strength is measured by breaking cylin- drical concrete
specimens in a compression-testing machine. The compressive strength is
Strength of concrete is directly related to the structure of the hydrated cement
paste. Air in concrete produces voids. Excess of water in concrete evaporate
Concrete has almost no tensile strength (usually measured to be about 10 to 15
% of its compressive strength), and for this reason it is almost never used without
(compressive strength). ▫ At a given w/c ratio, mortar is stronger than the
corresponding concrete. ▫ Cement paste and aggregate are elastic, concrete is
