Light-weight inorganic composite concrete and preparation method thereof

Abstract

The invention discloses a light-weight inorganic composite concrete and a preparation method thereof. The light-weight inorganic composite concrete is prepared from the following raw materials in parts by weight: 80-90 parts of ordinary Portland cement, 20-25 parts of superfine microbead, 15-20 parts of corn starch, 4-5 parts of shiitake culture material, 15-20 parts of vitrified microbead, 0.6-0.7 part of diethylenetriamine, 1.0-1.5 parts of n-butyl methylacrylate, 1.2-1.5 parts of sodium fluosilicate, 0.3-0.4 part of hydroxypropyl methylcellulose ether, 2-4 parts of barium zinc stabilizing agent, 4-6 parts of chlorinated paraffin wax and a right amount of water. The concrete has the characteristics of no pollution, no public nuisance, high safety and environmental protection. The superfine microbead and vitrified microbead are adopted to enhance the binding property of the concrete, thereby enhancing the compression resistance, folding resistance, aging resistance and water resistance of the concrete. Compared with the prior art, the light-weight inorganic composite concrete has the advantages of reasonable cost, obviously higher sound-insulation effect and the like, and is convenient for construction.

Description

technical field [0001] The invention relates to the field of building materials, in particular to a lightweight inorganic composite concrete and a preparation method thereof. Background technique [0002] The main building material used in structures in my country is concrete, and natural sand is its main fine skeleton. At present, natural sand is used in most areas. Natural sand belongs to local resources and is not renewable in the short term; with the increase of construction volume, Natural sand is nearly exhausted in many areas of our country. At the same time, due to the excessive mining of natural river sand will cause damage to the ecological environment, the mining of natural river sand has been strictly prohibited or restricted in many places, which has led to increasingly prominent contradictions between the supply and demand of engineering sand; the current concrete It does not have the above comprehensive performance or the cost is high, and it needs to be ...

[0002] The main building material used in structures in my country is concrete, and natural sand is its main fine skeleton. At present, natural sand is used in most areas. Natural sand belongs to local resources and is not renewable in the short term; with the increase of construction volume, Natural sand is nearly exhausted in many areas of our country. At the same time, due to the excessive mining of natural river sand will cause damage to the ecological environment, the mining of natural river sand has been strictly prohibited or restricted in many places, which has led to increasingly prominent contradictions between the supply and demand of engineering sand; the current concrete It does not have the above comprehensive performance or the cost is high, and it needs to be further improved to meet the needs of my country's deepening drilling construction, while improving economic benefits and promoting faster social progress
