由水泥、炉底渣、粉煤灰和复合外加剂制成的节能复合砌块专用保温砌筑砂浆(以下简称保温砂浆)具有良好的物理力学性能、热工性能和耐久性。研究表明:密度等级小于1050kg/m3的保温砂浆,导热系数小于0.25W/(mK),强度等级达到Mb5.0和Mb7.5,抗冻性能D25合格,固体废弃物(炉底渣+粉煤灰)利用率超过60%(重量比),同时具有优异的施工性能。保温砂浆对节能复合砌块在节能建筑上的应用有推动作用。
Energy-saving composite block made of cement, bottom slag, fly ash and composite admixture special masonry mortar (hereinafter referred to as insulation mortar) has good physical and mechanical properties, thermal performance and durability. The results show that the thermal insulation mortar with density less than 1050kg / m3 has thermal conductivity less than 0.25W / (mK), strength level up to Mb5.0 and Mb7.5, frost resistance D25, solid waste Ash) over 60% (by weight), with excellent workability. Insulation mortar on the energy-saving composite building blocks in the application of energy-saving have a catalytic role.
