Study on Low-Cost Reactive Powder Concrete and its Application

摘要

Reactive powder concrete (RPC) is a new kind of material with very high mechanical behavior and durability, however, high cost and complex procedure to make RPC result in hardly apply to engineering in large scale, a new low-cost RPC that compressive strength exceeds 130MPa was prepared with the replacement of quartz sand, crushed quartz and partial of silica fume by fly ash, slag and natural fine aggregate in the paper. Manhole cover that made from the low-cost RPC can meets the requirements of different situations, such as special road, motorway, etc.
