Dry powder thermal insulation masonry mortar prepared from waste aerated concrete
The invention provides dry powder thermal insulation masonry mortar prepared from waste aerated concrete, and relates-the technical field of building materials. The dry powder thermal insulation masonry mortar provided by the invention comprises the following components in parts by mass: 230-380 parts of Portland cement, 500-750 parts of waste aerated concrete fine aggregate, 50-100 parts of modified waste aerated concrete micro powder, 180-280 parts of water-quenched blast furnace slag, 40-90 parts of pottery sand, 18-40 parts of pearl expansive rock, 2-10 parts of hydroxypropyl methyl cellulose, 0.15-1 part of mortar glue, and 3-15 parts of a superplasticizer, wherein the modified waste aerated concrete micro powder is obtained by calcining waste aerated concrete micro powder, and the calcining temperature is 700-900 DEG C. The dry powder thermal insulation masonry mortar provided by the invention is reasonable in proportion, is close to a light thermal insulation building block in the aspects of air shrinkage deformation, dry density and thermal conductivity, has a good bonding effect with the light building block, and does not crack.
本发明提供了一种利用废弃加气混凝土制备的干粉保温砌筑砂浆，涉及建筑材料技术领域。本发明提供的干粉保温砌筑砂浆包括以下质量份数的组分：硅酸盐水泥230～380份；废弃加气混凝土细集料500～750份；改性废弃加气混凝土微粉50～100份；水淬高炉矿渣180～280份；陶砂40～90份；珍珠膨胀岩18～40份；羟丙基甲基纤维素2～10份；砂浆胶0.15～1份；高效减水剂3～15份；所述改性废弃加气混凝土微粉是将废弃加气混凝土微粉煅烧得到，所述煅烧的温度为700～900℃。本发明提供的干粉保温砌筑砂浆配比合理，在干缩变形、干密度、导热性能上与轻质保温砌块相接近，并且与轻质砌块粘结效果好，不开裂。
