本文利用粘土陶粒、粉煤灰、大粒径机制砂、高效泵送剂配制出LC20轻质混凝土,表观密度低至1500kg/m3,并经过实际试验成功完成了90m的泵送距离,提高了陶粒混凝土的工作度,成功完成陶粒混凝土的泵送,大粒径机制砂的使用提高了1碎石生产厂家的经济效益。
In this paper, LC20 light weight concrete is prepared by using clay ceramic, fly ash, large-size sand and high-efficiency pumping agent. Its apparent density is as low as 1500kg / m3, and the actual test has successfully completed the pumping distance of 90m, The work of ceramsite concrete, the successful completion of the pumping of ceramsite concrete, the use of large-size machine-made sand to improve the economic benefits of a gravel manufacturer.
