Effect of glass and polypropylene fibers in cementitious composites containing waste stone powder
Source abstract
Abstract
In this study, stone powder as a waste material was used to fabricate cementitious composite samples. Neat (non-modified) cementitious samples were composed of gravel, cement, sand, water, and waste stone powder. Flexural and compressive strength tests showed that flexural and compressive strength could be improved by increasing waste stone powder weight percentage. In addition, the experimental results illustrated that samples containing waste stone powder present more flexural and compressive strength in comparison with those fabricated without waste stone powder at constant cement weight percentage. In the next step, polypropylene and glass fibers were used in specimens containing waste stone powder. Consequently, flexural strength of fiber-reinforced composites was modeled by modifying “Equal Cross-Section Theory.” The results show that fibers increase flexural strength of specimens; meanwhile, waste stone powder does not have a significant effect on compressive strength. In another step, it was tried to make cementitious composite samples containing perlite as a light aggregate. Cementitious composites containing waste stone powder and perlite presented more flexural and compressive strength compared to samples without waste stone powder.
