Relation of Modulus of Elasticity with Compressive Strength--Gap-Graded Vs. Continuously-Graded Concrete
The most frequently used physical and mechanical properties of any structural concrete are unit weight, compressive strength, and modulus of elasticity. But heretofore only very meager and scattered information about them is available for gap-graded concrete, being far from adequate for practical design calculations. Unit weight, compressive strength, and modulus of elasticity were determined according to ASTM Standard Methods for both gap-graded and continuously-graded concretes of the same maximum-size coarse aggregate, practically equal compressive strength, and practically the same workability in the mix-design strength range of 4500 psi to 7500 psi to cover present structural concrete, reinforced or prestressed, leaning toward the higher strength range. Based on test data, two new dimensionally consistent equations, one for gap-graded concrete, and another for continuously-graded concrete, are proposed to relate modulus of elasticity linearly with compressive strength and unit weight for concretes of different unit weights. Another two dimensionless equations, one for gap-graded concrete and another for continuously-graded concrete, are proposed to relate modulus of elasticity with compressive strength and the modulus of elasticity of the coarse aggregate.
