Hubei Zhonglitong new material RPC subway evacuation platform: Reactive powder concrete (RPC for short) is a high-tech composite material composed of superfine reactive powder, cement, high-quality quartz sand, mineral admixture and high-strength fiber. It is prepared by optimized grading design and high temperature sealing and other specific processes. After high strength and high performance concrete, it is a cement-based material with super high strength, high durability, high toughness and good volume stability developed by using conventional cement and other materials in the mid-1990s. It is a kind of high performance concrete composed of DSP material and fiber reinforced material. This material combines the design principle of ultra-fine particle dense material and fiber reinforcement technology, and has a light and thin structural size. Under the same bearing capacity, the weight of RPC cover plate is about 40% of that of ordinary concrete cover plate, which is convenient to install.

Hubei Zhonglitong New Material Co., Ltd. is a manufacturer of subway evacuation platform in RPC urban rail transit section. It is an expert in customization of cement-based and concrete prefabricated components, which can be inspected on the spot.
