Preparation technology of special mortar for medium-sized concrete composite building blocks
The invention relates to the technical field of concrete, and discloses a preparation technology of special mortar for medium-sized concrete composite building blocks. Lightweight concrete comprises a material A and a material B. The material A comprises the following components in parts by weight: 37-43 parts of cement, 33-38 parts of quartz sand, 13-17 parts of water-washed river sand and 6-10 parts of fly ash. The material B is prepared from the following components in parts by weight: 1.5 to 1.9 parts of redispersible latex powder, 0.2 to 0.3 part of hydroxypropyl methyl cellulose, 0.05 to 0.15 part of starch ether, 0.1 to 0.2 part of pp fiber and 0.2 to 0.4 part of a water reducing agent. The components of the material A and the components of the material B are uniformly mixed respectively, and then are mixed together to obtain the lightweight concrete. The preparation process is simple and convenient to operate. The lightweight concrete contains redispersible latex powder, hydroxypropyl methyl cellulose, starch ether and pp fibers, so that the strength of the lightweight concrete is improved, the toughness is enhanced, and the lightweight concrete is not easy to crack.
本发明涉及混凝土技术领域，公开了一种中型混凝土复合砌块专用砂浆的制备技术，轻质混凝土包括A料、B料；A料包括以下重量份的各组分：水泥37‑43份、石英砂33‑38份、水洗河砂13‑17份、粉煤灰6‑10份；B料包括以下重量份的各组分：可再分散乳胶粉1.5‑1.9份、羟丙甲基纤维素0.2‑0.3份、淀粉醚0.05‑0.15份、pp纤维0.1‑0.2份、减水剂0.2‑0.4份；将A料、B料分别混合均匀后再混合到一起，得到轻质混凝土。本发明的制备工艺简单、操作方便；轻质混凝土中包含有可再分散乳胶粉、羟丙甲基纤维素、淀粉醚、pp纤维，使得轻质混凝土强度提高，韧性增强，不容易开裂。
