What are the application scope of cement blanket?

As a new environmental protection material, cement blanket has been widely used in construction, road engineering, post disaster reconstruction, ecological restoration and so on. Hanji new cement blanket has imported advanced technology from Europe and provided matching production equipment and technical formula.

The new type of cement blanket is a kind of soft cloth with cement-based composite materials inside. The surface is special canvas, and the interior is three-dimensional textile cloth and cement-based composite materials. When it meets water, it will hydration and form a hardened cement-based material system. It has the advantages of simple use, rapid solidification, environment-friendly, flexible application, high material strength, waterproof and fireproof, It is an outdoor material with great potential. At the beginning, it was proposed by two British scholars. In foreign countries, the application of cement blanket in road construction, ditch lining, slope protection, pipeline protection, roof protection and so on has been very mature, and has great application potential in the future, which provides a guarantee for a large number of cement blanket as building application materials.

1. Post disaster concrete blanket house

Cement blanket materials can be used to quickly build a temporary shelter, which can be used in disaster relief and provide a fire-resistant and antibacterial environment for residents. Such a building is also very simple, 24-hour concrete frame construction can, the whole house has a service life of more than 10 years.

2. Water conservancy and irrigation engineering

It is used for waterproof and permeable layer of water conservancy facilities such as reservoir, river bank, channel and drainage ditch.

3. Highway and railway protective belt

It is used for slope protection and isolation on both sides of highway and railway to prevent the damage of soil erosion, soil weathering, weeds and vegetation erosion on traffic infrastructure.

Main features of 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.
