Document Type and Number:
WIPO Patent Application WO/2021/012867
Kind Code:
A1
Abstract:
A preparation method for high-strength coral aggregate concrete under low air pressure conditions, comprising: taking cement, a mineral admixture, a coral aggregate, mixing water, as well as a water-reducing agent and a defoaming agent as materials; mixing the cement and the mineral admixture evenly to obtain a cementing material, loading the coral aggregate, seawater, the water reducing agent, the defoaming agent and 55-85% of the cementing material into a closed stirring system, stirring for 10-15 minutes under low air pressure conditions, and then loading the remaining cementing material into the mixing system to continue mixing for 10-15 minutes, so as to obtain the high-strength coral aggregate concrete. The obtained coral aggregate concrete has advantages such as a high mechanical performance index, a high density, good impermeability and durability, and also has the advantages such as using local materials and maximizing resource utilization in remote island reef construction projects.
