Study the Effect of Cement Waste on Some Mechanical Properties of Acrylonitrile-Butadiene Rubber

Abstract

The basic idea of this paper is to prepare and study the composite rubber material for the manufacturing of an important part in the grain transportation systems in silos of general company for grain trade namely rablat, where it was the experience of this rablat manufactured in the new silo of Hilla/Babylon province for a period of eight months in winches and vector chain was fully proven. In this paper, manufacturing rablat of rubber material; and other supported by brass bosh from Acrylonitrile-butadiene rubber (NBR) reinforced by two materials; first, cement waste from the southern general company, for cement emerging as a result of incidental to the process of calcination and grinding stone in depositing the oven and that has been added by 0–40 pphr with 1 μm grain size, and second silica extracted from the husks of rice which was added with a fixed amount 20 pphr and 10 μm grain size. Mechanical tests were done before and after the addition of cement powder residue and rice husks to rubber by Tansometer to measure the tensile strength, where the growth rate of crack was measured by fatigue device and hardness measured by Wallace bead load hardness. The results show that the rubber material developed and manufactured in this research are consistent with the mechanical properties of the original model with improved tensile strength and hardness with decreased fatigue.
