一例细砂卵石商品混凝土的设计与应用

Design and application of ready-mixed concrete with fine sand and pebbles

本文对细砂、卵石混凝土的有关性能进行了试验研究与分析,采用低水泥用量原则,优选出最佳砂率,配制出坍落度18cm以上且坍落度损失小的细砂卵石C25~C35商品混凝土,并提出了几点细砂卵石混凝土在实际施工中的建议。

In this paper,the authors made the test study and analysis on the properties of ready-mixed concrete with fine sand and pebbles.They used the principles of the low amount of cement,found out the optimized sand ratio,and mixed C25 ~ C35 ready-mixed concrete with more than 18cm slump and less slump loss.The concrete have been used in a number of local engineering with good result of using.Last,make a number of suggestions in using concrete with fine sand and pebbles in the actual construction.
