  • Effects of shape and size of aggregates in concrete

    How does the shape and size of coarse aggregates affect the properties of concrete? A Aggregate shape and surface texture influence the properties of freshly mixed concrete more than the properties of hardened concrete Roughtextured, angular, and elongated particles require more water to produce workable concrete than smooth, rounded compact aggregate Consequently, the cement contentincrease in aggregate size results in a decrease in the compressive strength of concrete Cook (1989) showed that, for compressive strengths in excess of 69 MPa (10,000 psi), smaller sized coarse aggregate produces higher strengths for a given watertocement ratio In fact, it is generally agreed that, although larger coarse aggregates can be usedEFFECTS OF AGGREGATE TYPE, SIZE, AND CONTENT ON CONCRETEThe maximum size of coarse aggregate that can be used in a mix depends on the size, shape, and reinforcing of a member, based on these "nottoexceed" guidelines (see Photos 5 and 6): 3/4 of the clear spacing between rebar or between rebar and forms (cover distance) 1/3 the depth of the slab 1/5 the narrowest dimension of a member Often aggregates are analyzed using combined grading of fineAggregate in Concrete Concrete Network
