Anti-seismic heat-insulating high-strength mortar

Abstract

The invention belongs to the field of construction materials, and particularly relates to anti-seismic heat-insulating high-strength mortar. The anti-seismic heat-insulating high-strength mortar comprises the following raw materials in parts by weight: 40-60 parts of ferro-nickel slag, 30-50 parts of ordinary Portland cement, 5-8 parts of gypsum, 5-9 parts of low-thermal-conductivity coefficient filler, 10-15 parts of coconut shred, 10-15 parts of high-silicon quartz sand, 15-20 parts of composite filler, 5-8 parts of potassium pyrophosphate, 3-5 parts of sodium dodecyl sulfate, 5-8 parts of cocamidopropyl betaine, and 5-8 parts of blue tungsten oxide powder. The heat-insulating performance and anti-corrosion performance of the mortar can be improved by ferro-nickel slag, blue tungsten, high-silicon quartz sand and coconut shred, the compatibility of raw materials of the mortar can be increased by adding the composite filler and cocamidopropyl betaine, the strength of the mortar can be greatly enhanced, so that the linear shrinkage of the mortar is small, and the anti-crack and durable performances are good.

Description

technical field [0001] The invention belongs to the field of building materials, and in particular relates to an anti-seismic and heat-insulating high-strength mortar. Background technique [0002] At present, the inner and outer walls of most building envelopes in my country still use ordinary cement sand that has been used for many years. This ordinary cement mortar has a high thermal conductivity and has a poor function of preventing heat transfer. Areas with large temperature differences often consume a lot of energy due to frequent heat exchange between hot and cold air. In order to solve the above problems, people try to add a certain amount of polystyrene or other plastic material particles to the ordinary cement sand, hoping to meet the requirements of the wall surface, especially the external wall surface, through the heat resistance characteristics of polystyrene or plastic particles. However, this improved wall mortar material still has defects such as poor waterp...

Problems solved by technology

[0002] At present, the inner and outer walls of most building envelopes in my country still use ordinary cement sand that has been used for many years. This ordinary cement mortar has a high thermal conductivity and has a poor function of preventing heat transfer. Areas with large temperature differences often consume a lot of energy due to frequent heat exchange between hot and cold air

In order to solve the above problems, people try to add a certain amount of polystyrene or other plastic material particles to the ordinary cement sand, hoping to meet the requirements of the wall surface, especially the external wall surface, through the heat resistance characteristics of polystyrene or plastic particles. However, this improved wall mortar material still has defects such as poor waterproof and moisture-proof performance, poor thermal insulation ability, and cracks caused by mortar shrinkage.
