Special heat insulating mortar for straw fly ash building blocks and preparation method of special heat insulating mortar
The invention discloses special heat insulating mortar for straw fly ash building blocks and a preparation method of the special heat insulating mortar, and relates to the technical field of building materials and environmental protection and energy conservation. The masonry mortar is prepared from the following components in parts by mass: 15 to 20 parts of cement, 60 to 65 parts of fine aggregate, 10 to 15 parts of glass beads, 0.04 to 0.05 part of hydroxypropyl methyl cellulose ether, 0.15 to 0.6 part of a concrete expansive agent, 0.25 to 0.75 part of dispersible latex powder and 5 to 7 parts of fly ash. The surface mortar is prepared from the following components in parts by mass: 15 to 20 parts of cement, 60 to 65 parts of fine aggregate, 10 to 15 parts of glass beads, 0.04 to 0.05 part of hydroxypropyl methyl cellulose ether, 0.15 to 0.5 part of corn straw, 0.75 to 2.5 parts of slaked lime and 7 to 9 parts of fly ash; and the ratio of water to cement used for pulping is 1.2-1.4. The straw and the glass beads are effectively utilized, damage to the environment caused by straw combustion is avoided, the preparation process is simple, the production cost is low, and the produced building mortar is excellent in various properties. The special heat insulating mortar has important significance on effective utilization of waste resources, environmental protection and building energy conservation.
本发明公开了一种秸秆粉煤灰砌块专用保温砂浆及其制备方法，涉及建筑材料和环保节能技术领域。砌筑砂浆按质量份数包括以下组份：水泥15‑20份、细骨料60‑65份、玻化微珠10‑15份、羟丙基甲基纤维素醚0.04‑0.05份、混凝土膨胀剂0.15‑0.6份、可分散性乳胶粉0.25‑0.75份、粉煤灰5‑7份；抹面砂浆按质量份数包括以下组份：水泥15‑20份、细骨料60‑65份、玻化微珠10‑15份、羟丙基甲基纤维素醚0.04‑0.05份、玉米秸秆0.15‑0.5份、消石灰0.75‑2.5份、粉煤灰7‑9份；制浆使用的水灰比皆为1.2‑1.4。本发明有效利用了秸秆和玻化微珠，避免秸秆燃烧对环境造成破坏，制备工艺简单，生产成本低，且生产的建筑砂浆各项性能优异。本发明对废弃资源的有效利用、保护环境和建筑节能具有重要意义。
