【摘要】:研究了泡沫剂对纤维、聚合物改性火山渣轻集料混凝土性能的影响。试验结果表明,通过掺入适量的泡沫剂对火山渣轻集料混凝土进行改性,可以使火山渣轻集料混凝土的和易性得到改善,抗压强度和抗折强度升高;当泡沫剂掺量为0.1‰时,大大降低了吸水率,显著提高了火山渣轻集料混凝土的抗渗性和抗冻性;同时,在火山渣轻集料混凝土中掺入泡沫剂,导热系数呈现下降趋势,当掺量达到4.0‰时,导热系数为0.122 W/(m·K),比不掺泡沫剂减小了30%。
[Abstract]:The effect of foaming agent on the properties of fiber-polymer modified volcanic slag lightweight aggregate concrete was studied. The experimental results showed that the volcanic slag lightweight aggregate concrete was modified by adding appropriate foaming agent. The easiness, compressive strength and flexural strength of volcanic slag lightweight aggregate concrete can be improved, and when the content of foaming agent is 0.1 鈥,
