高性能混凝土的抗压强度与收缩性能随龄期变化规律试验研究

Experimental investigation on time effects capability of high capability concrete

以粉煤灰作为掺合料、低水灰质量比/水胶质量比的高性能混凝土为试验对象,对不同水灰质量比/水胶质量比和不同掺入量,从成型到180 d龄期内的抗压强度、弹性模量以及收缩(自收缩、单面干燥条件下的总收缩)的混凝土时效性能进行试验研究。研究成果可为工程施工提供参考。

Experiments were carried out, which were focused on studying the effects of fly ash replacement content and water- to- cementitious mass ratio on the time - dependent compressive strength, elastic modulus and shrinkages of concretes cured for a period from curing to 180 d after curing. Reliability and validity of the design was proved by a series of trail took action in local.
