珊瑚礁砂配制扭王字块混凝土技术研究

Research on Preparation Technology of the Coral Sand in Accropode Concrete

珊瑚礁砂具有空隙率高、吸水率大、压碎值高等特点,研究了珊瑚礁砂在扭王字块混凝土中的应用。研究结果表明,使用适量的珊瑚礁砂取代机制砂,经过配合比设计能配制出工作性、强度及耐久性符合设计要求的扭王字块混凝土。

The main characteristic of coral sand is high porosity, high water absorption and high crushing value. The application of coral sand in accropode is studied in this paper. The results showed that,coral sand concrete whose strength and durability meet the design requirements has been made by taking the right amount of coral sand replace mechanism sand and adjusting the mix ratio.
