Conventionally, aerated concrete has been used as a building material for the purpose of reducing the weight of buildings and improving work efficiency, but when the surface of aerated concrete is exposed to the wind and rain, rainwater permeates through it. It has drawbacks such as weathering and low strength such as abrasion resistance and impact resistance, so various secondary reinforcements are used. However, these reinforcement methods simply apply or spray waterproofing agents to the aerated concrete, which destroys the coating film formed in a short period of time and does not provide sufficient lasting effects. In addition, these conventional methods have few methods for structurally increasing the mechanical strength of aerated concrete, and even if they are possible, they are extremely expensive.

Next, specific examples will be explained along the manufacturing process of lightweight cellular concrete of the present invention. Unsaturated plastic IJ Mix about 2% of a curing agent (for example, methyl chloride peroxide) and (or as necessary) a curing accelerator (for example, naphthenic cobalt) to the ester resin liquid and the resin liquid. , mix and stir uniformly, and add resin concrete in which 2 to 5 parts of bone phase (dry sand, etc.) to 1 part of resin liquid are evenly mixed.This is then molded into the lightweight cellular concrete board of the present invention. The material is poured into a formwork made of metal, wood, plastic molding, etc. that satisfies the specifications for the desired shape and size.

When pouring resin concrete, workability is better if the aggregate ratio is lowered and the fluidity is higher. To prevent distortion, it is effective to increase the aggregate ratio as high as possible.For this purpose, the amount of aggregate mixed at the beginning is reduced to create fluid resin concrete, and it is poured uniformly within the form. It is desirable that similar bones 4'A or another aggregate be secondarily dispersed at the stage where the aggregate is placed, so that the final aggregate ratio is about 3 to 5.

Although the manufacturing process of the present invention has been mainly explained above using an unsaturated polyester resin, other resin concretes as described above can also be manufactured using substantially the same process. These resin concretes develop high strength at an early stage and have high compressive strength. Therefore, the lightweight cellular concrete board of the present invention has a structure in which the resin concrete layer formed on the surface is integrated with the cellular mortar layer, so it is lightweight but has excellent strength of each 441i, compared to the conventional cellular concrete IJ-1-1. It has superior properties compared to the other 11.

The lightweight aerated concrete board of the present invention manufactured as above in 9 is particularly effective as a waterproof layer for flat roofs. Conventionally, in buildings made of reinforced concrete, flat roofs on rooftops were not waterproof enough to allow rainwater to leak, shortening the lifespan of dyed materials.For this reason, the waterproofing of flat roofs was carried out with great care.

LUJ Waterproofing has been constructed with sheet waterproofing material, thermal asphalt waterproofing, etc., but over a long period of time, the waterproofing layer will be partially removed. ? When a person walks on these waterproof layers, dirt gets into the waterproof layer and causes it to tear, causing water leakage.

For this reason, concrete block plates were laid on top of these waterproof layers to hold down and protect the waterproof layers. However, due to the The lightweight aerated concrete board of the present invention can be used to replace the conventional concrete block board described above. It has superior effects compared to In other words, 1. Since it is a concrete plate with internal air bubbles, it is lightweight and easy to handle. 1. It has excellent workability. Easy to maintain. In addition, since it has air bubbles inside, it has great insulation properties, there are no floating spots that can destroy the waterproof layer, and it has excellent soundproofing properties, so no sound is transmitted downstairs. Furthermore, because the surface is covered and reinforced with resin concrete, it has high strength such as compressive strength, and has excellent properties such as abrasion resistance and impact resistance, making it possible to increase the mechanical strength of flat roofs. .
