Lightweight and novel wall material with superfine slag powder and for building

Abstract

The invention discloses a lightweight and novel wall material with superfine slag powder and for a building. The lightweight and novel wall material with the superfine slag powder and for the buildingis prepared from the following raw materials in parts by weight: 25-46 parts of the superfine slag powder, 15-25 parts of iron powder, 20-40 parts of ceramsite, 5-15 parts of a water reducer, 3-16 parts of a foaming agent, 10-35 parts of coal ash, 10-20 parts of kieselguhr, 15-30 parts of cement, 20-50 parts of water, 5-15 parts of wood flour and 5-19 parts of borax. According to the lightweightand novel wall material with the superfine slag powder and for the building, a microstructure of cement paste is improved, and the compactness of the concrete is increased, so that the strength and durability of the concrete are improved, the self weight of the wall material is enabled to be light, the service life is prolonged, the mechanical properties are greater higher than a whole cement production reinforced concrete lightweight wall material for the building in aspects of crush resistance and hanging force, and good economical and social benefits are achieved. The concrete doped with the superfine slag powder has the characteristics of low heat of hydration, corrosion resistance, good mobility, high long-term strength, miniature prevention, improved interfacial bonding property of the concrete and the like.

Description

technical field [0001] The invention relates to a novel lightweight wall material for construction with slag micropowder. Background technique [0002] With the rapid development of modern building technology, high-rise, super high-rise and long-span buildings emerge in endlessly. The mass production and use of building materials not only builds convenient living facilities for human beings, but also has a negative impact on the earth's environment and ecological balance. Many traditional building materials are increasingly being challenged. In order to achieve the goal of sustainable development and reduce the environmental load of building materials to a minimum, it is particularly important to use and continuously develop energy-saving and environmentally friendly building materials. In the prior art, the reinforced concrete lightweight wall materials produced for construction are generally made of cementitious materials, sand, water, water reducing agent, foaming agent,...

AI Technical Summary

Problems solved by technology

In the prior art, the reinforced concrete lightweight wall materials produced for construction are generally made of cementitious materials, sand, water, water reducing agent, foaming agent, etc., and the cementitious materials are generally made of grade 42.5 or above. All cement, the production cost is relatively high, and the existing methods of producing reinforced concrete lightweight wall materials for construction are generally more complicated, which affects the development of lightweight wall materials
