大掺量粉煤灰高性能混凝土的试验研究

Experimental Study on PFA High Performance Concrete of High Replacement Levels

混凝土能否长期作为最主要的建筑材料,关键在于能否成为绿色材科,使之纳入可持续发展的轨道。针对施工情况,探讨了中等强度大掺量粉煤灰高性能混凝土的社会经济意义、工作性及力学性能,在大量试验的基础上,对不同掺量粉煤灰高性能混凝土的坍落度损失、抗压强度进行了分析。

Whether the concrete can remain to be the most important building material over a long period of time depends critically on whether it is a green material and can be put on the right of the sustainable development. In viewing the national conditions, this paper probes into the social and economic significance, workability, mechanical properties and durability of middle strength PFA high performance concrete of high replacement levels, and based on many tests, analyzes comprehensively on the slump loss, compressive strength, drying shrinkage and durability of PFA high performance concrete.
