Abstract

Provided is a beryllia-containing aerated concrete block. The block is composed of the following raw materials comprising, by weight, 22-24 parts of cement, 14-16 parts of quicklime, 12-14 parts of gypsum, 20-25 parts of fly ash, 0.1-0.2 parts of aluminium powder, 30-35 parts of iron sand tailings, 12-15 parts of calcium chloride, 1-2 parts ofberyllia, 3-5 parts of sulfamate water reducing agents, 3-5 parts of zinc oxide, 2-3 parts of tributyl phosphate, 1-2 parts of dodecyl betaine, 3-5 parts of sodium persulfate, 2-3 parts of oil foot, 2-3 parts of silane coupling agent KH5502, 2-3 parts of cross-linking agent TAC and 6-8 parts of sodium tripolyphosphate. The aerated concrete block is advantaged by high compressive strength, light weight, sound insulation, heat insulation, good heat retaining property, good anti-frost property, less contraction and the like. The aerated concrete block overcomes the defects of low strength and easy cracking of traditional aerated concrete blocks. Beryllia in the block is a good refractory material and can be fire-retardant.

Description

Air-entrained concrete building block containing beryllium oxide 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 as a kind of less energy-consumption, the New Building Materials of environment-friendly type, belong to the material of construction that country promotes, but because ordinary air-entrained concrete is made up of cement, flyash, unslaked lime, gypsum etc., there is the problems such as drying shrinkage value is large, intensity is low, infiltration, not corrosion-resistant, thermal insulation is not good, material source is single, therefore, be badly in need of air-entrained concrete building block technology is studied further, make the requirement further meeting market.
Summary of the invention
The object of this invention is to provide air-entrained concrete building block containing beryllium oxide and preparation method thereof, to solve the nonfireproof problem that current air-entrained concrete building block exists.
Technical solution of the present invention is as follows:
A concrete segment containing beryllium oxide, is characterized in that being made up of the raw material of following weight part: cement 22-24, unslaked lime 14-16, gypsum 12-14, flyash 20-25, aluminium powder 0.1-0.2, iron sand tailings 30-35, calcium chloride 12-15, beryllium oxide 1-2, sulfamate water reducer 3-5, zinc oxide 3-5, tributyl phosphate 2-3, empgen BB 1-2, Sodium Persulfate 3-5, oil foot 2-3, Silane coupling agent KH550 2-3, linking agent TAC 2-3, tripoly phosphate sodium STPP 6-8.
The preparation method of the described concrete segment containing beryllium oxide, is characterized in that comprising the following steps:
(1), flyash, calcium chloride are added suitable quantity of water, be heated to 70-80 DEG C, stir 15-20 minute, add oil foot, tripoly phosphate sodium STPP, stir 15-25 minute, then add Sodium Persulfate, Silane coupling agent KH550, stir after 10-15 minute, add gypsum, zinc oxide, linking agent TAC stir 15-20 minute, stir into mud;
(2), cement, iron sand tailings are added 55-70 DEG C of hot water mixing 10-15 minute, then, add other materials such as the mud of step (1) gained and aluminium powder, unslaked lime, sulfamate water reducer, beryllium oxide, stir 10-15 minute, obtain the slurry that water content is 30-36%;
(3), by slurry pour into a mould, to send in 40-50 DEG C of drying room after precuring 1.5-2.5 hour, cut into building block base, on the outer wall of building block base, be coated with last layer dimethyl silicone oil;
(4), steam press maintenance in still is sent in building block.
The air-entrained concrete building block that the present invention produces, wherein adopt oil foot composition, through initiator modification, add the hydrophobicity of building block, greatly improve its infiltration ability, building block of the present invention uses at community exterior wall, last more than 3 years, do not find wall leakage phenomenon, and adopt traditional air-entrained concrete building block, annual Jun You resident family appearance infiltration in spring.Adopt beryllium oxide to be good refractory materials in the present invention, there is better resistance to fire action, can fire protection flame retarding.
The air-entrained concrete building block that the present invention produces has that ultimate compression strength is high, light weight, sound insulation, heat insulation, good heat preservation performance, anti-freezing property and the advantage such as contraction is little thereof, solves the defect that traditional air-entrained concrete building block intensity is low, easy to crack.
