Abstract

The invention discloses a lightweight concrete exterior wall insulation building block and a production method thereof. The lightweight concrete exterior wall insulation building block is prepared by mixing the following raw material components in proportion by weight: 20-50 of cement, 20-40 of fly ash, 8-20 of fine sand, 1-8 of calcareous material, 5-16 of plant filler, 0.2-0.5 of adjuvant, 8-15 of water and 0.3-0.7 of foaming agent. The production method of the lightweight concrete exterior wall insulation building block comprises the following steps of: forming raw material slurry by uniformly mixing production raw materials in mixing proportion; adding the water to the foaming agent, and generating uniform and stable bubbles by using a foaming device; mixing the bubbles with the raw material slurry so as to prepare bubble concrete slurry; and casting the bubble concrete slurry into a mold and curing. According to the lightweight concrete exterior wall insulation building block and the production method of the lightweight concrete exterior wall insulation building block, the plant filler, such as sawdust or crop straw powder, is mixed, so that the weight is reduced, the flexibility is improved, and the improvement on the strength of a finished product and the cracking prevention are favored; and the bubbles are enabled to be uniformly distributed in the raw material slurry by adding the foaming agent, so that not only is the weight of the building block reduced, but also the heat preservation and heat insulation effects are improved.

Description

A kind of light weight concrete heat-insulating building block for outer wall and production method
 
Technical field
The present invention relates to material of construction, particularly a kind of building construction heat-insulating building block for outer wall and production method thereof.
Background technology
At present, China has building construction outer wall body material now, mainly contain clay solid brick, structural clay tile, perforated brick, shale brick, concrete segment, burn-free cement brick etc., above outer wall body material ubiquity thermal conductivity is high, heat-proof quality is poor, can not satisfy country to the requirement of Building Energy Saving, use above material also to need to do the thermal insulation separation thermosphere at exterior surface of wall or internal surface and could satisfy the related specifications requirement, and still have the defectives such as heat insulating effect is bad, weight is large.
Summary of the invention
The object of the invention is to overcome the deficiencies in the prior art, a kind of insulation, heat insulation, sound insulation are provided, lightweight, the measured heat-insulating building block for outer wall of matter provides the production method of heat-insulating building block for outer wall simultaneously.
For achieving the above object, technical scheme of the present invention is: heat-insulating building block for outer wall is formed by following composition and weight ratio mixed preparing: cement 20-50, flyash 20-40, fine sand 8-20, calcareous material 1-8, plant-filled material 5-16, auxiliary agent 0.2-0.5, water 8-15, whipping agent 0.3-0.7.
Described plant-filled material is that in agricultural crop straw, sawdust, the rice husk one or more are mixed by the arbitrary proportion beyond zero, pulverizes the particle or the powder that form.
The particle diameter of described plant-filled material is 0.1-1.5mm.
Described calcareous material is that in gypsum, grey calcium, the lime powder one or more are mixed by the arbitrary proportion beyond zero.
Described auxiliary agent is that in hardening accelerator, accelerating chemicals, the water reducer one or more are mixed by the arbitrary proportion beyond zero.
The production method of heat-insulating building block for outer wall of the present invention is as follows:
1, the cement in the raw materials for production, flyash, fine sand, calcareous material, auxiliary agent, water are pressed the even mix of proportioning;
2, add the plant-filled material by proportioning, evenly mix becomes the raw material slurry;
3, whipping agent is added 30-100 times of water after, produce even, stable bubble with foam device;
4, bubble is mixed with the raw material slurry, make the foamed concrete slurry;
5, the foamed concrete slurry is poured into the mold by building pump;
6, quietly stop maintenance after 2-4 days, demoulding pile;
7, natural curing is 20-30 days.
The ratio of foam is that lather volume is the 0.4-0.7 cubic meter in one cube of slurry in the described foamed concrete slurry.
The present invention cooperates by plurality of raw materials, admixture vegetalitas stopping composition (such as sawdust or agricultural crop straw powder etc.), vegetalitas stopping composition lighter weight, not only alleviate building block weight but also increased the snappiness of building block, reduce the fragility of building block, what is more important absorbs moisture content in the early stage, and the later stage of condensing provides moisture content, is conducive to improve the intensity of finished product and prevents cracking; Add simultaneously whipping agent, bubble is evenly distributed in the raw material slurry, bubble is independent, do not connect, and formed the gas chamber of bubble diameter 0.3-1 millimeter, both alleviated building block weight, improved again heat insulating effect.
The present invention compared with prior art has the following advantages:
1, good effect of heat insulation exempts to do other external-wall heat-insulation material.Be lower than 0.17W/mK with the made building block thermal conductivity of the present invention through the experiment detection, insulation capacity is excellent, and its heat insulating effect is 3-5 times of stack pile structural clay tile, the house that uses insulation blocks to build, its comfortableness improves greatly, the summer without extremely hot, winter without cold.And the insulating layer of external wall construction that can save expensive numerous Xu reaches insulation and goes along with sb. to guard him two-in-one.
2, soundproof effect is good, because its special structure and the mortar when building by laying bricks or stones completely spread the propagation of blocking-up sound wave, soundproof effect is very outstanding, can external noise is effectively isolated, keep the privacy of separate space.
3, heat-insulating building block for outer wall body of wall unit square rice is lightweight, and it is than the lightweight 40%-60% of other materials for wall unit square rice.The weight of materials for wall descends, and can impel again the weight of skeleton construction to descend, and the gross weight of buildings is lower like this, is conducive to reduce construction cost and prevents earthquake disaster.
4, save the consumption of manpower, the on-the-spot sand-cement slurry of minimizing.Because the quality with the made heat-insulating building block for outer wall of the present invention is light, the building block geometrical dimension of producing is large, be the 3-15 of common outer wall body material geometrical dimension doubly, can greatly save manpower, reduce the expense of manually building by laying bricks or stones, the sand-cement slurry of using simultaneously also greatly reduces, and provides possibility for shortening the completion time of project.
5, be conducive to the anti-leakage of outer wall impermeable.Heat-insulating building block for outer wall is put in the water, and is not heavy.The not water absorption character of its excellence is conducive to prevent the appearance of common fault of building (exterior wall leakage etc.).
6, the made block surfaces of the present invention flat and not only, can exempt to plaster, after jointing is finished directly batch putty, coat, also can plaster, paste facing tile.
7, Hydroelectric Project Construction body of wall fluting, body of wall are hung weight.Hollow brick wall Hydroelectric Project Construction body of wall fluting, body of wall extension weight all need special processing, and very trouble all can easily realize and adopt heat-insulating building block for outer wall to need not other processing.
8, the flyash of heat-insulating building block for outer wall admixture and plant-filled material, utilization of waste material, energy-conserving and environment-protective.Can greatly reduce industrial residue to the pollution of environment on the one hand, reduce again the pollution of burning tangerine pole pair air, increase simultaneously local common people's income.
