我队地处长白山脚下。这里天然浮石储藏很丰富。安图县建材厂对这种浮石的物理性能进行了试验,并且用水泥作胶结材料,制作浮石混凝土,其试件抗压强度为100～110公斤/厘米~2,容重为1130公斤/米~3,导热系数为0.2千卡/米·小时·℃。每立方米浮石混凝土材料用量:500号水泥180公斤,浮石0.72立方米,火山砂0.29立方米。我们对浮石混凝土砌块做了一些探索性的应用,现简介如下。
Our team is located at the foot of Changbai Mountain. Natural pumice is abundant here. Antu County Building Material Factory conducted tests on the physical properties of this pumice stone and used cement as cementing material to make pumice stone concrete. The compressive strength of the sample was 100 to 110 kg/cm~2, and the bulk density was 1130 kg/m~ 3. The thermal conductivity is 0.2 kcal/m·h·°C. Per cubic meter of pumice concrete material usage: 500 cement 180 kg, pumice 0.72 cubic meters, volcanic sand 0.29 cubic meters. We have made some exploratory applications to pumice concrete blocks. The brief introduction is as follows.
