无熟料水泥混凝土短柱正截面承载力试验研究

The Experimental Research of Impact Section Bearing Clinker Cement Compression Short Column

本文以工业废弃物(粉煤灰、矿渣)和低纯度石灰粉取代100%的水泥,制备无熟料水泥混凝土短柱,研究其在不同水胶比作用下的混凝土及钢筋的应力-应变关系以及荷载-位移关系。研究表明:无熟料水泥混凝土短柱的破坏情况及应力-应变曲线与普通混凝土短柱相似,极限承载力可以达到普通混凝土短柱的90%以上。

In this paper,no clinker cement concrete short columns are prepared by replacing 100% of cement with industrial waste( fly ash,slag) and limestone,to study the stress-strain relationship and load displacement relationship of concrete and steel bars under different water cement ratio.Studies have shown that the failure condition and stress-strain curve of no clinker cement concrete short columns are similar to those of ordinary concrete short columns,and the ultimate bearing capacity can reach more than 90% of the ordinary concrete short columns
