摘要
在砂浆中加入粉煤灰,不但能降低砂浆的成本,而且还能够改善砂浆的施工性能、提高砂浆保温性能。在满足加气混凝土(泡沫混凝土)抹面砂浆粘结强度高、收缩率低的前提下,粉煤灰掺量30%时,所配制的砂浆导热系数为0.1953W/m.K,与加气混凝土(泡沫混凝土)砌块导热系数接近,具有良好的保温效果。
Adding fly ash into mortar can not only save costs of mortar,but also improve the workability and heat preservation performance of mortar.To meet the premise of high adhesive strength and low shrinkage of the aerated concrete（foamed concrete） surface mortar,the thermal conductivity of prepared mortar is 0.1953W/m？K when the content of fly ash is 30%,which is near the thermal conductivity of the aerated concrete（foamed concrete） block,and it has good heat preservation effect.
