What are the benefits of using the new cement blanket?

As a new type of environmental protection material, cement blanket has been widely used in military and civil construction, road construction site, post disaster reconstruction, ecological restoration, furniture design and composite pipe materials. It is composed of three-dimensional fiber blanket and composite concrete dry powder material. It has the properties of heat preservation, rapid setting and hardening, flame retardant, waterproof, windproof, bending resistance, corrosion resistance, etc. Due to the limitations of production equipment, staff Technology and sense of responsibility, the domestic cement blanket has quality defects (poor compressive strength, low flexural strength, water seepage, non frost resistance, vulnerable and easy to corrode, etc.), causing irreparable losses to users. Another problem is that the cement blanket prepared by the factory has fixed specifications (5m and 10m), and the thickness is single (10mm). In the specific construction, most of them need cutting and trimming, resulting in too many connection points and affecting the construction progress.

"New construction technology of cement blanket on site", field preparation, random installation, no thickness limit, no size limit. The thickness ranges from 6 mm, 10 mm, 15 mm, 20 mm and 25 mm, and the length varies from 1 m, 2 m, 5 m, 10 m, 20 m, 50 m and 100 m. As a new construction technology, "new construction technology of cement blanket on site" solves the quality shortage of cement blanket preparation and makes up for the quality defect of incomplete watering and solidification of cement blanket. More importantly, "new construction technology of cement blanket on site" as an upgrade of product quality of cement blanket has expanded the application field and expanded the environmental requirements required for construction: construction can be carried out at minus 10 degrees.

Main features of new 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

Hanji cement blanket does 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.
