Abstract

With wide application of the high performance concrete in Engineering, the research and application of high performance concrete admixture are attaching more and more attention by researchers. Although researches are more mature on the aspects of fly ash, slag, silica fume and other non-biological materials, the research is behindhand in the aspect of biological material such as straw ash, which contains a large amount of silica dioxide and has a certain amount of volcanic ash activity. It is considered that Heilongjiang Province as a major agricultural province, moreover, burning straw pollution is particularly serious in summer and fall. It is beneficial to manufacture straw ash high performance concrete and improve the strength and durability of the concrete. According to recent analysis on physical and chemical properties of the straw ash, it is completely feasible to improve the strength and durability of the concrete by adding straw ash to it in a reasonable method. It can be sure that, if after in-depth research, the straw ash as a concrete admixture would have a wide foreground in the future.
