Abstract: In this paper,it discusses the application of epoxy resin concrete,introduces the ultimate bearing capacity of covers of epoxy resin concrete and analysis of capacity theory and experiment result on covers of epoxy resin concrete.High performance polymer concrete is used to make the manhole cover instead of iron’s nowadays,and the paper analyzes the theory and test results of epoxy resin concrete,the performance of epoxy resin concrete is superior in fact,this kind of covers is the thinnest in all the covers.

Abstract: 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.
