纤维添加量对泡沫混凝土性能的影响规律研究

泡沫混凝土是一种新型建筑材料,随着泡沫混凝土的应用范围的扩大,部分结构需要泡沫混凝土具有较高的强度,在泡沫混凝土中掺入纤维是提高泡沫混凝土强度的一种方法,文章通过向泡沫混凝土中掺入玄武岩纤维,采用拟合分析分析了纤维对混凝土干密度流动性及抗压强度的影响规律。分析结果表明:随着玄武岩纤维的加入及纤维长度的增加,泡沫混凝土的抗压强度提高,流动性变差,干密度降低。

Foam concrete is a new kind of building material. With the expansion of the application scope of foam concrete, some structures need high strength of foam concrete. Adding fiber into foam concrete is a method to improve the strength of foam concrete. The effect of basalt fiber on dry density fluidity- and compressive strength of foamed concrete is analyzed by fitting the basalt fiber into the foamed concrete. The results show that with the addition of basalt fiber and the increase of fiber length, the compressive strength of foam concrete increases, the fluidity becomes worse, and the dry density- decreases.
