Abstract

Provided is a lightweight aerated concrete block. The aerated concrete block is characterized by comprising, by weight, 20-25 parts of cement, 15-20 parts of quicklime, 10-12 parts of gypsum, 10-15 parts of fly ash, 0.2-0.3 parts of aluminium powder, 8-10 parts of polypropylene fiber, 8-10 parts of mineral oil, 5-8 parts of clay, 30-35 parts of plant ash, 3-5 parts of ammonium persulfate, 10-12 parts of oil foot, 12-15 parts of sodium metasilicate and 3-5 parts of polyvinyl alcohol. The aerated concrete block takes plant ash as a main raw material, the plant ash is lightweight, so that the weight of block is reduced greatly, and the building load is reduced.

Description

Lightweight air-entrained concrete building block and preparation method thereof
Technical field
The invention belongs to a kind of building material technique, tool is a kind of concrete segment and preparation method thereof entirely.
Background technology
Novel wall material gas concrete is as New Building Materials a kind of less energy-consumption, environment-friendly type, belong to the material of construction that country promotes, but because common gas concrete is made by cement, flyash, unslaked lime, gypsum etc., have that drying shrinkage value is big, intensity is low, infiltration, not corrosion-resistant, problem such as thermal insulation is not good, material source is single, therefore, urgent need is further studied for the air-entrained concrete building block technology, makes further to satisfy the requirement in market.
Summary of the invention
The purpose of this invention is to provide lightweight air-entrained concrete building block and preparation method thereof, so that air-entrained concrete building block weight is lighter, reduce building load.
Technical solution of the present invention is as follows:
A kind of lightweight air-entrained concrete building block is characterized in that being made by the raw material of following weight part: cement 20-25, unslaked lime 15-20, gypsum 10-12, flyash 10-15, aluminium powder 0.2-0.3, polypropylene fibre 8-10, mineral oil 8-10, clay 5-8, plant ash 30-35, ammonium persulphate 3-5, oil foot 10-12, Starso 12-15, polyvinyl alcohol 3-5.
The preparation method of described lightweight air-entrained concrete building block is characterized in that may further comprise the steps:
(1), clay, plant ash are added suitable quantity of water, be heated to 90-100 ℃, stirred 5-10 minute, add oil foot, Starso, stirred 25-35 minute, add ammonium persulphate then, stir after 30-45 minute, add polyvinyl alcohol, gypsum stirring 20-30 minute, stir into mud;
(2), cement is added 50-60 ℃ of hot water mixing 5-15 minute, then, add the mud of step (1) gained and unslaked lime, aluminium powder, flyash, other material of mineral wet goods, stirred 10-15 minute, obtain the slurry that water content is 30-35%;
(3), with slurry cast, send in the 40-60 ℃ of drying room after precuring 1.5-2.5 hour, cut into the building block base, be coated with the last layer dimethyl silicone oil at the outer wall of building block base;
(4), building block is sent into steam press maintenance in the still.
 
The air-entrained concrete building block that the present invention produces, wherein adopt the oil foot composition, through the initiator modification, increased the hydrophobicity of building block, improved its infiltration ability greatly, building block of the present invention body of wall outside the residential quarter uses, last more than 3 years, do not find the wall leakage phenomenon, and adopt traditional air-entrained concrete building block that all have resident family infiltration to occur annual spring.Adopt plant ash as main raw material among the present invention, have lightweight characteristics, alleviate building block weight greatly, reduce building load.
The air-entrained concrete building block that the present invention produces has advantages such as ultimate compression strength height, light weight, sound insulation, heat insulation, good heat preservation performance, anti-freezing property and contraction thereof be little, has solved traditional air-entrained concrete building block intensity defective low, easy to crack.
Embodiment
A kind of lightweight air-entrained concrete building block is characterized in that being made by the raw material of following weight part (kilogram): cement 20, unslaked lime 15, gypsum 12, flyash 10, aluminium powder 0.3, polypropylene fibre 10, mineral oil 8, clay 8, plant ash 35, ammonium persulphate 3, oil foot 10, Starso 15, polyvinyl alcohol 3.
The preparation method of lightweight air-entrained concrete building block is characterized in that may further comprise the steps:
(1), clay, plant ash are added suitable quantity of water, be heated to 90-100 ℃, stirred 5-10 minute, add oil foot, Starso, stirred 25-35 minute, add ammonium persulphate then, stir after 30-45 minute, add polyvinyl alcohol, gypsum stirring 20-30 minute, stir into mud;
(2), cement is added 50-60 ℃ of hot water mixing 5-15 minute, then, add the mud of step (1) gained and unslaked lime, aluminium powder, flyash, other material of mineral wet goods, stirred 10-15 minute, obtain the slurry that water content is 30-35%;
(3), with slurry cast, send in the 40-60 ℃ of drying room after precuring 1.5-2.5 hour, cut into the building block base, be coated with the last layer dimethyl silicone oil at the outer wall of building block base;
(4), building block is sent into steam press maintenance in the still.
The cubes that the hollow brick that the present invention is produced cuts into 100mm * 100mm * 100mm carries out Performance Detection, and detected result is as follows: ultimate compression strength 4.98Mpa, and shrinkage value 0.47mm/m, density is 0.53, is starkly lower than traditional building block, frost resistance loss of strength 21%.
