膨珠混凝土是一种新材料,它的突出优点是既能承重又能保温,试验证明,其物理力学性能与普通重混凝土相近,它的后期强度甚至比普通重混凝土还要高。但厚度28厘米的膨珠混凝土墙板能否满足北京地区的保温要求,是大家很关心的问题;为了进一步检验这种膨珠混凝土外墙板在实际上房使用中的保温效果,我们在76年3月室内试验基础上,又在76年元月15日至24日历时十昼夜,亦即在冬季最冷的天气条件下,对使用 Expanded-bead concrete is a new material. Its outstanding advantage is that it can bear both weight and heat. Tests have shown that its physical and mechanical properties are similar to those of ordinary heavy concrete, and its late strength is even higher than ordinary heavy concrete. However, whether the 28cm-thick expanded concrete wallboard can meet the insulation requirements in Beijing is a matter of great concern to everyone; in order to further examine the thermal insulation effect of this kind of expanded concrete outer wallboard in actual use, we are On the basis of the indoor trials in March of the year, and on the calendar days of January 15 to 24 of the year 76, ten days and nights, that is, in the coldest weather conditions in winter, the use of
