摘要
运用最紧密堆积理论对高强耐磨材料的集料进行配比设计,通过提高高强耐磨水泥基材料的集料堆叠密实度,提高其强度和耐磨性能。并参照RPC材料设计原理,通过外加剂的优选降低水固比、矿物掺合料掺量的复配以及增强材料的使用改善材料内部的多尺度结构,从而优化材料的施工工作性、抗裂性能、耐磨性,达到提高耐磨材料的服役性能与年限。
The closest packing theory is employed todesign the aggregate grading of the high-strength wear-resistant and cement-based material to improve itsstrength and anti-abrasion property by means of increasethe packing density of aggregate. According to the PRC(reactive particle concrete) principle of material design,the W/S (water to solid) ratio of the high-strength wear-resistant and cement-based material could be modifiedwith selected additives, the multi-size structure withinthe material could be improved by blending in mineraladmixtures and enhancing materials. In this way, itsworkability, anti-breaking property and abrasionresistance are optimized, and the servicing performancesand its lifetime are also improved at the same time.
