The mineral makeup of the aggregate also influences the modulus of elasticity of concrete. In a study by Aitcin and Mehta, they tested four different types of aggregates: diabase, limestone, gravel, and granite. Their test results showed that the limestone and diabase aggregates gave the highest values for the elastic modulus.

MECHANICAL PROPERTIES OF MIXTURES OF CRUSHED LIMESTONE AGGREGATES AND MILLED BITUMINOUS CONCRETE TREATED WITH CEMENT. Mixtures of crushed granular material and milled bituminous materials, in proportions 100/0, 50/50, 25/75 by mass respectively, treated with 5% by mass cement were tested in uniaxial compression, uniaxial tension and in flexure for strength and modulus of elasticity

The Young’s modulus of elasticity is the elastic modulus for tensile and compressive stress in the linear elasticity regime of a uniaxial deformation and is usually assessed by tensile tests. Limestone is a type of carbonate sedimentary rock. Most of the salt produced is crushed and used in the winter on roads to control the
