摘要
利用粉煤灰陶粒代替天然骨料生产出抗压强度达到MU3.5的陶粒混凝土自保温砌块,并对其砌筑墙体的保温性能进行了测试。研究表明:粉煤灰陶粒混凝土自保温砌块墙体的实测传热系数低于1.0 W(/m2·K),保温性能明显优于烧结空心砌块和普通混凝土空心砌块。
It was produced that the ceramsite concrete self-insulation block using flyash ceramsite, which the compressive strength meet the requirements of MU3.5, and the thermal insulating performance of the ceramsite concrete self-insulation block was also studied.The result showed that the heat transmission coefficient ofceramsite concrete self-insulation block masonry was less than 1.0 W/（m2·K）,the thermal insulating performance was obviously better than fired hollow block and normal concrete hollow block.
