What is the difference between cement blanket and concrete?

We all know that concrete is an important raw material for building construction. However, in some complex terrain environment, it is often necessary to manually mix concrete and other materials, which can not only mix unevenly, but also produce a lot of dust, which is time-consuming, laborious and inefficient. In order to solve these problems, our uncle invented a new material. Let's take a look at the magic Technology: Yes, this time, the subversion of traditional concrete is the concrete blanket, which usually looks like an ordinary blanket, but after pouring water, it will quickly become a hard concrete layer! This unique material can be easily installed. It has the toughness of textiles. It can be hung vertically or laid in grooves. It can be cut at will. The size is only 15kg per square meter. It is very convenient to transport. After watering, its strength and life are equivalent to the traditional concrete, and it has excellent waterproof performance. It can be widely used in railway, water conservancy, highway, agricultural irrigation and other fields. Most importantly, the use of this new material can save 90% of the traditional materials and shorten the construction period by 60%.

And this new type of concrete is what we call a new type of cement blanket. The cement blanket is a kind of soft cloth impregnated with cement, which will react with water and harden into a very thin waterproof and fireproof durable concrete layer. The cement blanket is made of 3D fiber matrix woven with polyethylene and polypropylene filament, and contains dry concrete mixture with special formula. The main chemical components of calcium aluminate cement are Al2O3, Cao, SiO2 and Fe2O3. The bottom of the canvas is covered with polyvinyl chloride (PVC) backing to ensure that the cement blanket is completely waterproof. During site construction, there is no need for any concrete mixing equipment on site, as long as the cement blanket is simply watered or soaked in water to make it hydrated. After solidification, the fiber can strengthen the concrete and prevent cracking. At present, the cement blanket is 10 mm thick.

Main features of Hanji cement blanket

1) Easy to use

Cement blanket can be supplied in bulk in large rolls. It can also be provided in rolls, convenient for manual loading and unloading and transportation, without the need for large lifting machinery. The concrete is prepared according to the scientific proportion, which does not need to be prepared on site, and the problem of excessive hydration will not occur. Cement blanket can be solidified in both water and sea water.

2) Rapid solidification molding

Once the hydration reaction occurs, the cement blanket can still be processed within 2 hours, and it can harden to 80% strength within 24 hours. According to the special requirements of users, special formula can be used to achieve rapid solidification or delayed solidification.

3) Environment friendly

Cement blanket is a low-quality and low-carbon technology. In many applications, the amount of material used is 95% less than that of common concrete. Because of its limited alkali content and low scouring rate, it has little impact on local ecology.

4) Application flexibility

The cement blanket has good drapability and can follow the complex shape of the covered object surface, even form a hyperboloid shape. The cement blanket before setting can be cut or cut by ordinary hand tools.

5) High material strength

The fiber in the cement blanket can enhance the strength of the material, prevent cracking, and absorb the impact energy to form a stable failure mode.

6) Long term durability

The cement blanket has good chemical resistance, wind and rain resistance, and will not degrade under the sun.

7) Waterproof characteristics

The bottom surface of the cement blanket has a waterproof layer, which makes it completely waterproof and enhances the chemical resistance of the material.

8) Fire protection characteristics

The cement blanket will not support combustion and has good flame retardant properties. When it is on fire, the smoke is very small and the emission of dangerous gases is very small. The cement blanket has reached the b-s1, d0 grade of the European building material flame retardant standard.
