Abstract
The invention provides a construction partition used light wallboard and a preparation method thereof. The light wallboard comprises Portland cement, pulverized fuel ash, furnace slag, an expansion agent, clay porcelain granule, fluvial sand, expanded perlite, comprehensive materials including leftovers from production line, waste and old half-finished products, raw materials obtained by pulverizing and screening the waste and old half-finished products. The process method comprises the steps of adding more than 8 percent of the expansion agent to light concrete mixture; helically extruding and molding the mixture after automatic batch weighing, beating and mixing; the mixture is piled up and cured, and inspected before the product is delivered. The light wallboard is characterized in that by adding the expansion agent to the admixture, expansion energy is introduced; the chemical shrinkage of lightweight aggregate concrete is compensated through the expansion in volume, thus eliminating the shrinkage cracks of the wallboard; the compactness of lightweight aggregate concrete is improved; the impermeability is improved; the production process is simple and operated easily at low cost.
Description
Technical field
The present invention relates to a kind of light wall board for partition of buildings and preparation method thereof.
Background technology
Concrete light wall panel is as a kind of novel wall material, have light weight light weight, intensity high, characteristics such as fast, energy-conserving and environment-protective, fire prevention, protection against the tide and civilized construction are installed, current being widely used in the building, development prospect is wide.At present, the composition of producing Light trabs mainly comprises cement, flyash, polyvinyl alcohol, magnesium chloride, six pieces of sodium phosphates, magnesia etc., also interpolation such as sawdust or the string etc. that have.Above-mentioned Light trabs since raw material select for use with proportioning on difference, so have the moisture absorption, anti-halogen, yielding, produce surface checking, intensity reduction etc. thus, use until influence is normal.
Summary of the invention
The purpose of this invention is to provide a kind of light wall board for partition of buildings and preparation method thereof; Through a large amount of tests; Employing is the new prescription of raw material with portland cement, flyash, slag, expansion agent, leca, river sand etc.; Also fully use production line leftover bits and pieces, waste and old semiproduct and waste and old finished product, thereby overcome the defective that exists in the existing product preferably.
The component and the proportioning that realize Light trabs of the present invention are:
Component:
Portland cement, flyash, slag, expansion agent, leca, river sand, expanded perlite, comprehensive material, wherein comprehensive material comprises production line leftover bits and pieces, waste and old semiproduct and the raw material of waste and old finished product behind crushing screening;
Proportioning (by weight percentage):
Portland cement accounts for 20-40; Flyash accounts for 1-4; Slag accounts for 26-28; Expansion agent accounts for 1-4; Leca accounts for 2-5; River sand accounts for 26-28; Expanded perlite accounts for 0.5-2.5; Comprehensive material accounts for 4-8.
Above-mentioned component and proportioning also comprise:
Said expansion agent accounts for 8-12 of portland cement.
Said proportioning is that portland cement accounts for 20-35; Flyash accounts for 2-4; Slag accounts for 27-28; Expansion agent accounts for 2-3; Leca accounts for 3-5; River sand accounts for 27-28; Expanded perlite accounts for 1-2; Comprehensive material accounts for 5-7.
Said proportioning is that portland cement accounts for 26.6; Flyash accounts for 3.3; Slag accounts for 28; Expansion agent accounts for 2.67; Leca accounts for 4; River sand accounts for 28; Expanded perlite accounts for 1.3; Comprehensive material accounts for 6; Surplus is a water.
Said expansion agent accounts for 10 of portland cement.
The preparation method who realizes Light trabs of the present invention is:
1. each composition is mixed by proportioning;
2. be that 0.37:1 adds water and stirs by the ratio of water and cement;
