玻璃纤维增强泡沫混凝土性能试验研究

Properties of foamed concrete with fiber glass reinforcement

在泡沫混凝土中加入不同掺量玻璃纤维,制成纤维泡沫混凝土复合材料,测定了它的物理力学性能。结果表明,加入玻璃纤维增加了泡沫混凝土的抗压强度和抗折强度,极大地改善了韧性,并在一定程度上抑制了早期干缩开裂,而且对导热系数影响不大;因此,加入玻璃纤维可以有效改善泡沫混凝土的性能。

The properties of the compound material which is prepared by adding different fractions of fiber glass to foamed concrete were experimentally investigated. Results show that with the fiber reinforcement, the compression strength and flexural strength were increased, the toughness was highly enhanced, and the shrinkage at early ages restricted while the thermal conductivity unchanged. It is suggested that incorporating fiber glass in concrete can effectively improve the properties of foamed concrete.
