摘要
本文根据灰砂砖的表面特点，研究了灰砂砖砌筑砂浆的合理配比。做成标号为2．5到15MPa的多等级水泥砂浆和水泥石灰混合砂浆。通过对比砂浆的各种物理力学性能，指出外加剂的关键作用以及用于制备专用砂浆的可能性。
On thc basis of thc surface features of sand - lime bricks, rational mixturf ratios ofmasonry mortars for sand - lime bricks are studicd, rand cement mortars and composite cement- limemortars of different grades ranging from 2.5 to 15 MPa are prepared. By comparing various physicaland mecbanical properties of the mortars, the key functions of the additives and the possibilities ofpreparing special mortars with additives are givcn in this paper.
