What is a cement blanket?
Cement blanket scientific name concrete canvas (concretecloth), is a kind of soft cloth impregnated with cement, when exposed to water, it will undergo hydration reaction and harden into a very thin waterproof and fireproof durable concrete layer, according to the raw materials used and manufacturing process, the product is divided into two types of cement blanket products: G and D. The main components of the cement blanket: The concrete canvas is made of a three-dimensional fiber composite structure (3Dfibrematrix) woven with polyethylene and polypropylene filaments, and contains a specially formulated dry concrete mix (Dryconcretemix). The main chemical components of calcium aluminate cement are Al2O3, CaO, SiO2, Fe2O3. The underside of the canvas is covered with a polyvinyl chloride (PVC) backing.
Application fields of cement blankets: 1. Water conservancy engineering (rivers, scenic lakes, canals, etc.) 2. Traffic engineering (highways, railways, bridges, subways, etc.) 3. Agricultural fields (aquaculture, animal husbandry, agricultural irrigation) 4. Emergency projects (temporary tents, flood fighting and rescue, soft foundation treatment) 5. Environmental engineering (windbreak and sand fixation, landfills, sewage treatment plants) 6. Marine engineering (submarine optical cables, bridge piers, reclamation slope protection) Product features of cement blankets: 1. Reinforced and impermeable (can replace the original cloth, film, blanket, Grilles and other geotechnical materials) 2. Reinforcement (in terms of engineering protection, because the cement blanket is a flexible reinforcement material, it will not be damaged with the subsidence or cracking of the foundation, and can replace the original cement prefabrication or stone and other products) 3. Long service life (the service life of the project can reach more than 20 years, the maintenance cost is low, and the project budget is greatly reduced) 4. Convenient construction (cement blanket has low requirements for foundation treatment standards, simple construction, convenient and fast) Several specifications of cement blanket: DW-6 (thickness 6mm, gram weight 7kg) DW-7 (thickness 7mm, gram weight 8.5kg) DW-8 (thickness 8mm, gram weight 10kg) DS-10 (thickness 10mm, gram weight 12kg) DS-12 (thickness 12mm, gram weight 15kg) GW-6 (thickness 6mm, gram weight 8kg) GW-12 (thickness 12mm, gram weight 15kg) Note: According to the product marking, G-high-grade, D-low-grade, S-medium-strong, W-low-strength Construction steps of cement blanket: 1. Cutting Tools Required: Utility knife, Grinding and cutting machine Technical points: Cement blankets can be cut with basic hand tools, but the dust in the material will dull the knife, so it is recommended to change the blade frequently, and for large projects, a grinder can be used. 2. Laying laying method: manual laying, crane auxiliary technical points: before laying, it is necessary to remove sharp debris, manual laying of 2 people can be operated, or the crane can be used to cooperate with manual operation, according to the content of the project to choose the appropriate laying method, water conservancy projects need to be laid in the direction of the water flow, from upstream to downstream construction. 3. Lap joint Tools required: electric hand drill, hammer, U-shaped nails, drills, expansion bolts, pressing strips.
