3 Properties of Concrete

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 some form of reinforcing Its compressive strength depends upon many factors including the quality and proportions of the ingredients and the curing environment
