稻草纤维混凝土性能试验研究

Experiment Study on the Performance of Straw Fiber Concrete

通过一系列试验,得到同一配合比混凝土中掺入不同比例、不同形状稻草纤维后,混凝土和易性、抗压强度、劈裂抗拉强度、抗折强度、自重等性能的变化规律,大大改善了混凝土的韧性,其抗压强度和抗折强度随着掺量的增加而降低,折压比先增加后降低。稻草纤维混凝土能够改善混凝土性能,降低工程成本,节约社会能源。

Through a series of experiments, the properties rules of the concrete with the same mix proportion and adding straw fiber in different proportion and different shapes are obtained, including its workability, compressive strength, splitting tensile strength, flexural strength, weight. The concrete toughness is increased, and its compressive strength and flexural strength are decreased with the increasing mixing amount of the straw fiber. The ratio of compressive strength and flexural strength is raised at beginning then reduced. Straw fiber concrete can improve the performance of concrete, reduce the construction cost, and save the social energy.
