Abstract

The invention discloses quickly-cured slurry for on-site spray and construction. The quickly-cured slurry is a material for building on-site sprayed and constructed walls in the building industry, has the advantages of quick curing, light weight and self-insulation, and can be used for on-site spray and construction of walls.

Description

The rapid solidification slurry is built in a kind of on-the-spot spray

The present invention is an application number: 201210129148.6, the applying date: on April 28th, 2012, denomination of invention: the house internal partition wall that a kind of on-the-spot spray is built, divide an application.

Technical field

the invention belongs to building field, relate to a kind of on-the-spot construction of spraying the house internal partition wall of building.

Background technology

Traditional wall is by brick, builds materials such as fast, cement, mortar and pile up and form, and its shortcoming is that 1. weight is heavier, increases the basis and the structural behavior requirement of monolithic architecture thing; 2. it is numerous and diverse to construct, and labour intensity is big, and long construction period is wasted a large amount of manual works; 3. waste energy, contaminate environment, the material of the usefulness of building a wall is adding the energy that needs labor man-hour, and causes environmental pollution; In recent years, having emerged many novel walls, generally all is to adopt interlayer or batten to carry out assembly unit, solved traditional wall Heavy Weight, waste energy, the defective of environmental pollution, long construction period, but have following defective again; 1. do not meet people's life style, be not easy to secondary decoration; 2. metope is not easy to handle, and is easy to generate " hollowing cracking "; 3. can't handle the ornament of outstanding metope; 3. be inconvenient to transport; 4. for the body of wall of interlayer grouting formula, need template, and can't realize being in the milk during near the roof plentiful at body of wall

Summary of the invention

to the above defective of existing wall, the present invention has realized the house internal partition wall that a kind of on-the-spot spray is built, and by grid system, connects net, and on-the-spot spray is built the rapid solidification slurry and formed; One's duty case invention has realized that a kind of on-the-spot spray builds the rapid solidification slurry, and its composition comprises: cement, gypsum, expansion polyphenyl particle, sand, additive; The ratio of each component is according to strength of wall body, and the requirement of indexs such as water tolerance is adjusted, and generally its weight ratio is the cement of 1%-50 %; The gypsum of 10 %-, 80 %, the expansion polyphenyl particle of 0.1%-10%, 0.01 %-30% additive; The sand of 25%-35% has rapid solidification, can realize the building wall method of on-the-spot spray walling body; Self-heat conserving, in light weight, there are not advantages such as contraction.

Cement is silicate cement, ordinary Portland cement, slag cement, aluminosulfate cement, quick hardening Portland cement, low heat portland blast-furnace-slag cement, moderate-heat portland cement, composite Portland cement, Portland fly, Portland pozzolana cement in its integral part.

In its integral part gypsum be with the plaster of paris, desulfurated plaster be raw material production plaster of Paris, semi-hydrated gypsum, have the dehydrated gyp-of good coagulating hardening performance.

The expansion polyphenyl particle adopts the granules of polystyrene of recovery pulverizing and the EPS granules of polystyrene of New Development in its integral part.

additive comprises calcium sulphate retarder, spun glass, polypropylene fibre and the various fibers that are applicable to gypsum mortar and sand-cement slurry etc.

beneficial effect of the present invention is: has rapid solidification, can realize the building wall method of on-the-spot spray walling body, and self-heat conserving, in light weight, there are not advantages such as contraction.

Embodiment

are the cement of 15 % with weight ratio, 55% gypsum, 0.15% EPS granules of polystyrene; 0.01% calcium sulphate retarder, 0.01% polypropylene fibre, 28.3% sand mixing stirring; Be transported to add water behind the job site and stir after, can use.
