Steel formwork cleaning method and steel formwork cleaning cement mortar
The invention discloses a steel formwork cleaning method and steel formwork cleaning cement mortar. The steel formwork cleaning method comprises the steps that a steel formwork is obliquely arranged relative to the horizontal plane, and the surface of the steel formwork faces upwards; the surface of the steel formwork is wetted by water; prepared cement mortar is paved on the surface of the steel formwork to form a cement mortar layer with a certain thickness; the cement mortar is prepared by uniformly mixing and stirring the following components in parts by mass: 390-420 parts of water; 345-375 parts of cement; 80-120 parts of fly ash; 960-1140 parts of sand; 70-100 parts of soil; 3.0-4.0 parts of a water reducing agent; and 90-130 parts of an expanding agent; after the cement mortar layer is hardened to a certain strength and cracked, peeling occurs, the cement mortar layer on the steel formwork is removed; and the surface of the steel formwork is washed with water. According to the method, pollutants on the surface of the steel formwork can be cleaned in a one-time adhesion mode, the cleaning difficulty is small, the cleaning efficiency is high, the cost is low, no pollution is caused to the environment, and no harm is caused to human health.
本发明公开一种钢模板清理方法及钢模板清理水泥砂浆，该钢模板清理方法包括：将钢模板相对于水平面倾斜设置，表面朝上；水湿润钢模板表面；通过配制的水泥砂浆摊铺到钢模板表面上形成一定厚度水泥砂浆层；其中水泥砂浆由以下成分按照质量比混合搅拌均匀调配而成：水，390‑420；水泥，345‑375；粉煤灰，80‑120；砂，960‑1140；土，70‑100；减水剂，3.0‑4.0；膨胀剂，90‑130；待水泥砂浆层硬化至一定强度开裂起皮后，清除钢模板上的水泥砂浆层；水淋洗钢模板表面。本发明能够对钢模板表面的污染物进行一次性粘附清理，其清理难度小、清理效率高、成本低、对环境无污染、对人体健康无损害。
