Abstract

The invention discloses a manufacturing technique of reactive power concrete (RPC) products, belonging to the methodological technical field of the manufacturing technical process of the reactive power concrete (RPC) products in new building materials. The method comprises the following steps: according to the approaching process of raw material preparation, the raw material preparation is checked; according to the composition measured by the raw material mass mixture ratio, the raw material is measured; the checked raw material preparation is charged to a mixing plant for being mixed by utilizing charging equipment; the mixed reactive power concrete (RPC) is injected into a product mould to be formed; the formed product is maintained with the steam and hot water according to the curing temperature control requirement; the maintained product is stored according to the storing requirement. The manufacture technique is easy to be realized, has simple and convenient operation and high production efficiency, solves the technique bottleneck preparing the large scale commercial process of the reactive power concrete (RPC) products, and is suitable for manufacturing various reactive power concrete (RPC) products.

Description

technical field [0001] The invention relates to a production process method of an active powder concrete product, which belongs to the technical field of manufacturing new building materials, and specifically belongs to the technical field of the production process method of the active powder concrete product in the new building material. Background technique [0002] Reactive Powder Concrete (RPC) is a new type of concrete material developed by France in the mid-1990s with many advantages such as high strength, high toughness, and high durability. It was first used in nuclear reactor waste Storage container making. It is composed of graded quartz sand, cement, admixtures, admixtures and other main parts. In order to improve the toughness and ductility, high-strength special steel fibers are added, and the microstructure of the finished product is improved by high-temperature steam curing during the condensation and hardening process. . The strength grade of RPC can be div...
