Abstract:

In recent days the problem faced by the construction industry is acute shortage of raw materials. We have responsibility to reduce the effect the application of concrete materials to environmental impact. The concrete should be used as efficiently as much as possible. In structural design, an ideal situation in material saving is to reduce the weight of the structure without having to compromise on its strength and serviceability. Partial replacement of the concrete below the neutral axis is an idea that can create reduction in weight and savings in materials. In this paper, an experimental investigation is on partial replacement of concrete below the neutral axis by placing bricks with spacing and without spacing. Specimens of solid RC beams and two composite beams with different variations are casted and tested under two-point flexure loading. The results of Load deflection relationship, Load strain relationship, first crack, Ultimate load, concrete saving and reduction of Self weight of the beam are compared and effects are studied.
