Abstract:

This project assesses the effects of aggregate type and size on the mechanical properties of concrete, viz., on the compressive and flexural strengths, and on the modulus of elasticity. Explored are three aggregate gradations (No. 57, No. 467, and No. 357) consisting of two aggregate types (natural and crushed). Concrete made according to the specification for the Ohio Department of Transportation (ODOT) standard Class C mix provides the baseline for mechanical properties. The properties of the six concrete mixes produced are compared, in order to determine if aggregate gradation and type have a significant effect, using the following tests at 3, 7, 28, 56 and 90 days: (a) Compression; (b) Modulus of rupture; and (c) Modulus of elasticity. A series of environmental tests are documented in a companion report submitted under this contract.
