Construction method of reinforced concrete wall
The invention relates to the field of building construction, and provides a construction method of a reinforced concrete wall aiming at the problem that existing concrete is difficult to meet the strength requirement of a reinforced concrete wall body. The method comprises the following step of S1, measurement and line laying; S2, building a pouring formwork; S3, pre-embedding reinforcing steel bars; S4, preparing concrete; S5, pouring concrete; and S6, disassembling the pouring formwork. The concrete comprises the following components in parts by mass of 20-25 parts of Portland cement, 10-12parts of water, 75-80 parts of sand, 10-15 parts of fly ash, 5-7 parts of mineral powder, 0.5-1 part of a silane coupling agent, 1-3 parts of fatty alcohol polyoxyethylene ether, 0.5-1 part of O-nitrododecane ether and 0.01-0.02 part of 6-phenyl-3-pyridazinone. Through mutual cooperation of fatty alcohol polyoxyethylene ether, O-nitrododecane ether and 6-phenyl-3-pyridazinone, the compressive strength and the anti-cracking strength of the reinforced concrete are improved, the reinforced concrete wall is less prone to cracking when subjected to load, and the concrete is easier to meet the strength requirement of the wall body.
本发明涉及建筑施工领域，针对现有的混凝土难以满足钢筋混凝土墙体对强度的要求的问题，提供了一种钢筋混凝土墙体的施工方法，包括以下步骤：S1、测量放线；S2、搭建浇筑模板；S3、预埋钢筋；S4、制备混凝土；S5、浇筑混凝土；S6、拆卸浇筑模板；混凝土包括以下质量份数的组分：硅酸盐水泥20‑25份；水10‑12份；砂75‑80份；粉煤灰10‑15份；矿粉5‑7份；硅烷偶联剂0.5‑1份；脂肪醇聚氧乙烯醚1‑3份；邻硝基十二烷醚0.5‑1份；6‑苯基‑3‑哒嗪酮0.01‑0.02份。通过采用脂肪醇聚氧乙烯醚、邻硝基十二烷醚与6‑苯基‑3‑哒嗪酮互相协同配合，有利于增强钢筋混凝土的抗压强度以及抗裂强度，使得钢筋混凝土墙体在受到荷载时更加不容易开裂，使得混凝土更容易满足墙体对强度的要求。
