【摘要】 在分析外墙外保温抗裂砂浆开裂机理——存在薄层结构失水、化学反应收缩、界面不一致变形、外界环境影响等方面的基础上,介绍了KH抗裂砂浆采用高效释水材料克服薄层结构失水、采用微膨胀组分克服化学反应收缩、采用改性纤维分散抗裂砂浆表面应力、采用小分子聚醚类材料减少砂浆收缩、采用适量聚合物改善砂浆脆性的复合抗裂原理,在此基础上,对KH抗裂砂浆的性能和经济成本进行了进一步分析,结果表明,采用多种材料抗裂技术对于提高抗裂砂浆的抗裂能力具有性能和成本优势。更多还原

【Abstract】 Principle of motar cracking is introduced in this paper that water dissipating of folium, shrinkage of chemical reaction, transmutation of interface and influence of environment. Based for the reason, five method consist of efficiency water assimilating materials for thin layer dissipating water in sooner, expander for chemistry shrinkage of motar, special fiber for Solving Surface Stress of anti-crack motar, small molecules polyether for reducing motar shrinkage and powder for improve the brittle motar is used in KH anti-crack motar. The perfomence and economy is introduced in this paper, the reslut is that the motar is possessed superiority in perfomence and economy.更多还原
