Description

[0002] RPC is the abbreviation of reactive powder concrete, which is a newly developed new type of concrete with ultra-high strength, high toughness and extremely low permeability. It overcomes the low flexural tensile strength of high-strength concrete (HSC), the difficulty of construction pouring due to reinforcement reinforcement, and the cracking of concrete. It is a new type of concrete with ultra-high mechanical properties and durability prepared according to the principle of minimum defects, and has broad application prospects. However, due to its powdery nature, it takes a lot of time to mix it on site when it is used. Therefore, in order to save construction time, it is often prefabricated into standard blocks.
