摘要
随着加气混凝土砌块用量的增加,其配套抹面砂浆的应用已经越来越普及,为了和砌块强度相匹配,抹面砂浆抗压强度相对较低,因此容易造成其抗渗性能偏低,吸水率大,导致砌块墙体抗渗性能极低甚至没有抗渗性能,特别是外墙体和卫生间等结构部位的渗漏现象屡见不鲜。本文研究了常见的憎水剂品种和掺量对抹面砂浆抗渗性能的影响,同时分析了憎水剂对砂浆粘结强度的影响。
With the increase of the amount of aerated concrete block, the application of plastering mortar has been becoming more and more popular, In order to match and block strength, compressive strength of mortar plastering is relatively low, so easy to cause the impermeability of the low, high water absorption, leading to block wall impermeability is very low or even no impermeability, especially the leakage phenomenon of wall body and toilet structure parts repeatedly see not fresh. This paper studies the effects of waterproof agent＇ s variety and admixture on the impermeability of plastering mortar, also analyzed the influence of the waterproofing agent on the adhesive strength of the mortar.
