Abstract:
Slender mortar beams, prepared with different sand concentrations, were subjected to a series of bending tests consisting of instantaneous loading and unloading, to prolonged creep tests, and to strength and density tests, to establish the influence of the volume concentration of the sand on the rheological parameters of the mortar. Results show that up to a volume concentration of 50 percent, rigidity, density, and strength increase slightly and almost linearly with sand concentration. In addition, the stress-strain relationship is also linear in this range up to failure.
