Abstract

The properties of lightweight concrete containing pumice treated with sodium hypochlorite (NaOCl) were experimentally investigated in this study. The study used treated pumice as 100% replacement of fine and coarse aggregates in concrete mixtures. Untreated pumice aggregates were used to prepare reference mixtures. In addition, the study investigated the effect of sodium hypochlorite on pumice properties. The concrete compressive strength at ages of 7 and 28 days was tested. The results showed that the compressive strength of concrete that contained treated pumice increased by 200% as compared to concrete containing untreated pumice. The pumice aggregate treated with NaOCl increased the pumice strength and improved its physical characteristics as the mean of specific gravity and abrasion resistance.

碱性溶液处理浮石轻量混凝土的性能研究

试验研究了次氯酸钠(NaOCl)处理浮石轻量化混凝土的性能。本研究采用处理过的浮石100%替代混凝土混合料中的粗、细集料。采用未经处理的浮石骨料制备参比混合物。此外，研究了次氯酸钠对浮石性能的影响。试验了混凝土在龄期7天和龄期28天的抗压强度。结果表明:掺加浮石的混凝土抗压强度比未掺加浮石的混凝土提高200%;经NaOCl处理的浮石骨料提高了浮石强度，改善了其比重平均值和耐磨性等物理特性。
