Compressive strength

This study also contributes to reducing environmental pollution caused by plastic and glass waste as well as current construction brick production methods. The results show that the bulk density, compressive strength, and bending strength of brick samples made from PET plastic and glass waste are higher than those of burnt clay brick samples, while water absorption is much smaller than that of burnt clay brick samples.

This paper presents the experimental results of the viscosity and its influence of cement paste on both the segregation of the concrete mixture and the compressive strength of EPS-C. The research revealed that a viscosity of cement paste below 50 mPa.s results in segregation of the concrete mixture.
