LIMESTONE AS AN AGGREGATE FOR CONCRETE IN ACCORDANCE WITH RESULTS OF LITERATURE

The strength properties and moduli of elasticity of limestone fluctuate over a wide range. It is stated that it is better to use gravelly sand than limestone in concrete and that limestone is not suitable as an aggregate for wearing courses which are subjected to much stress. However, broken limestone generally increases the compressive strength of concrete, and shrinkage and creep are slight. The adhesion of cement to limestone is good, and corrosion is reduced by limestone. Heat expansion is slight, and fire resistance good. It is concluded that the influence of limestone is predominantly favorable, but further research is recommended. /TRRL/
