Description

A kind of production method of multi-functional air-entrained concrete building block
Technical field
The present invention relates to a kind of production method of multi-functional air-entrained concrete building block.
Background technology
Air-entrained concrete building block is a kind of light porous, insulation, fire protecting performance is good, can follow closely, can saw, can dig and have There are the New Building Materials of certain shock resistance.Early in the '30s initial stages, China begins to produce this product, and makes extensively With.For example：In Shanghai International Hotel, Shanghai mansion, Foochow building, People's Bank of China's building contour level building.It is a kind of excellent Good New Building Materials, and there is environmental protection.But the formula of current miscellaneous air-entrained concrete building block It is not quite similar, production technology is also not quite similar, causes in performance also gap.
The content of the invention
It is an object of the invention to provide a kind of life of the multi-functional air-entrained concrete building block with superior physical property Production method.
Technical problem solved by the invention can be realized using following technical scheme：
A kind of production method of multi-functional air-entrained concrete building block, it is characterised in that comprise the following steps：
1) dispensing, is counted by weight, and the air-entrained concrete building block raw material include following components：250-350 parts of water；Aluminium 3-8 parts of powder；60-80 parts of gypsum；80-90 parts of lime；150-200 parts of tailings；150-200 parts of silt；30-50 parts of clinker；Fine coal It is grey 60-80 parts；70-90 parts of cement；3-8 parts of additive；30-50 parts of foam stabilizer；5-20 parts of soda ash, the wherein silica of tailings More than content 90wt%, more than the dioxide-containing silica 80wt% of silt, more than the dioxide-containing silica 80wt% of clinker；
2) mix；
3) initial set of getting angry is carried out in first room of supporting after pouring into a mould, temperature is 45-60 DEG C, and just the foster time is 2 hours, after the completion of just supporting Cutting；
4) steam press maintenance, by step 3) base substrate of well cutting sends into still kettle together with bed die, and base substrate enters closes after kettle First vacuumized before kettle door, logical steam, vacuum is 800 × 105Pa, then slowly sends into steam and boosts, then support stage by stage Shield, first in vapour pressure 8 × 105Constant pressure 5h at Pa, 175 DEG C of vapor (steam) temperature, then in vapour pressure 9 × 105Pa, 190 DEG C of vapor (steam) temperature Lower constant pressure 3h, finally in vapour pressure 10 × 105Constant pressure 2h at Pa, 190 DEG C of vapor (steam) temperature, constant pressure maintenance is gradually depressured after terminating, Gradually discharge steam recovers normal pressure, opens kettle door, hauls out the mould equipped with finished product；
5) finished product is processed, and is gone out after kettle, is tested, and then carries out classification stacking.
In a preferred embodiment of the invention, count by weight, the air-entrained concrete building block raw material include with Lower component：

Because air-entrained concrete building block thermal conductivity factor is low, thermophoresis is slow, is highly resistant to fire, and it can be protected to tie Structure is not by influence of fire.Its refractoriness of air-entrained concrete building block is one-level refractory material more than 700 DEG C, when temperature is at 700 DEG C Intensity was not damaged in the past, and belonged to inorganic incombustible in itself, and toxic gas will not be produced at high temperature.
4th, sound insulating and absorbing performance is good
The sound insulation not having with common buildings material and sound absorption qualities.
5th, water permeability resistance can be good
It is particularly suitable for the more area of typhoon, heavy rain and makees materials for wall.
6th, it is "dead"
Air-entrained concrete building block employs "dead" raw material.Therefore, product complies fully with state health standards, category In environment-friendly and green building materials.
7th, shock resistance is good
Because aerated concrete density is light, overall performance is good, and inertia force is small during earthquake, so with certain antidetonation energy Power.
8th, durability is strong
Through experiment, air-entrained concrete building block compression strength is more than 25,000 grams/cm, equivalent to No. 125 clay bricks and The compression strength of Dinas brickes.
9th, machinability is good
Air entrained concrete has good processing characteristics.Can saw, can dig, can follow closely, energy milling, can bore.And it can manufacture In journey plus reinforcing bar, very big convenience and flexibility are brought to construction.
10th, shrinkage value is small
The air-entrained concrete building block of the present invention is used as siliceous material, its shrinkage value as a result of silt, the clinker of high-quality Only 0.3-0.5MM/M, the small quality material of shrinkage value, it is ensured that wall will not ftracture.
