The Influence of the Coarse Aggregate Size on Mechanical Properties of Reinforced Concrete Beams

Abstract:

This paper gives the influence of the coarse aggregate size on the mechanical properties of the beam with different coarse aggregate sizes under static loads. In the research, three reinforced concrete beams with three different coarse aggregate sizes separately are tested. The stains and the deflections of the beams under the static loads are measured. The results show that under the action of the same loads, the maximum strains of the reinforced concrete beams with the big and the small aggregate size separately are larger than that of the beam with mixed aggregate size, and the deflection of the beam with the big aggregate size is larger than that of the beam with small aggregate size. In the loading process, the changes of the normal section strain of the reinforced concrete beams are satisfied the assumption of the plane section.
