摘要
目前水运工程中多使用泵送混凝土,可从外掺料、砂率变化、碎石级配等方面优化配合比,提高耐久性混凝土的可泵送性。
With the increase of application of pumped concrete in port ＆ waterway engineering at present,the mixing ratio of concrete is optimized from mixing admixtures, variation of rate, and grading of crushed stone, etc.to improve the pumping capacity of durable concrete.
