Energy-saving dry powder type building mortar

Abstract

The invention discloses energy-saving dry powder type building mortar which consists of the following raw materials in parts by weight: 260-330 parts of Portland cement or slag cement, 405-585 parts of common sand, 10-50 parts of electric furnace slag, 10-30 parts of scrap, 5-15 parts of dry powder lime, 2-5 parts of red mud, 3-5 parts of silt and 22.8-27.9 parts of dry powder latex, wherein all the raw materials are weighed according to the weight parts after being dried and screened, and then physically mixed to obtain the granular or powdery product; and the product in bags or in bulk is conveyed to a construction site and can be directly used after being mixed with 123-155 parts of water. The energy-saving dry powder type building mortar disclosed by the invention is highly energy-saving, green and environment-friendly and convenient to construct and store, has stable and reliable quality and can stay as long as the building.

Description

technical field [0001] The invention relates to the technical field of building materials, in particular to a novel energy-saving dry powder building mortar. Background technique [0002] Traditional mortar is an on-site mixing product, because it is difficult to control the accuracy of measurement, resulting in great fluctuations in mortar quality. In addition, the raw materials of traditional mortar are single in nature. During the coagulation and hardening process, water evaporates to form more pores; at the same time, the shrinkage performance of cement-based hardened body and polystyrene board is quite different, so there is no difference at the interface between polystyrene board and mortar. Higher stress is evenly distributed, and the stress is in a thermodynamically unbalanced state and tends to be distributed spontaneously and evenly. This effect and the effect of the outside world often cause wall cracking, water seepage, plastering layer void swelling, falling off...

[0002] Traditional mortar is an on-site mixing product, because it is difficult to control the accuracy of measurement, resulting in great fluctuations in mortar quality

In addition, the raw materials of traditional mortar are single in nature. During the coagulation and hardening process, water evaporates to form more pores; at the same time, the shrinkage function of cement-based hardened body and polystyrene board is quite different, so there is no difference at the interface between polystyrene board and mortar. Higher stress is evenly distributed, and the stress is in a thermodynamically unbalanced state, tending to spontaneously distribute evenly. This effect and the effect of the outside world often cause wall cracking, water seepage, plastering layer void swelling, falling off, etc. Phenomenon, unable to meet the different requirements of modern new building materials for mortar
