Q:What is the difference between GRC wallboard and aerated block wall?

Because of the composite structure of GRC surface layer and high thermal resistance core material, GRC composite wallboard has high strength, high toughness, high impermeability, high fire resistance and weather resistance, and has good insulation and sound insulation performance.The surface material for producing GRC composite exterior wall panels is the same as other GRC products. The core layer can be matched with cast-in-situ cement expanded perlite mixing material, or prefabricated insulation materials (such as rock wool board, polystyrene foam board, etc.). Generally, the anti - roll forming process is adopted. When the molding is made, the face of the wallboard is contacted with the surface of the template, so the quality of the face of the wallboard is better. The GRC surface of wallboard is usually made by direct injection method. The built-in reinforced concrete ribs are made of welded steel frames and C30 bean stone concrete made from sulphoaluminate cement.

Q:GRC jet equipment prices?

The whole set, from agitator to delivery to jet, is probably in 12 thousand.

Q:GRC roofing made waterproof layer, how much is one square metre?

The "Rainbow" brand PBC-328 non curing rubber asphalt waterproof coating is made of high quality asphalt, functional polymer modifier and special additives scientifically optimize mixture, maintain a viscous paste waterproof material in application state. The product has outstanding creep properties, and comes with outstanding applications such as healing, anti seepage, anti channeling, fatigue, aging and stress free.

Q:What is the best type of cement used in plain GRC components? What's the best filler? How dose glass fiber be controlled?

Cement: Cement usually used in GRC, mainly consisting of fast hard sulphoaluminate cement, low alkalinity sulphoaluminate cement, ordinary portland cement, and white Portland cement.Fiber: fibers used in GRC materials must be alkali resistant glass fibers, including alkali resistant fiberglass, roving, alkali resistant fiberglass, short cut, alkali resistant fiberglass mesh. Europe and the United States require GRC in the use of glass fiber zirconia content of not less than 16.5%, China requires the use of ordinary portland cement, zirconia content of not less than 16.5%.

Q:What material is GRC?

GRC is the abbreviation of English Glass fiber Reinforced Concrete, and the Chinese name is glass fiber reinforced cement. GRC is a kind of fiber cement composite material with alkali resisting glass fiber as reinforcing material and cement mortar as base material. GRC is a kind of material that expresses designer's imagination through shape, texture, texture and color.

Q:What about the air leak in the flue?

There are many kinds of problems. See where they leak. If the valve leaks, it is necessary to remove the ceiling to check the valve. If there is an air leak in the flue, it is necessary to repair the leak.

Q:What are the features and capabilities of GRC components?

From the material composition, the thermal conductivity is less than the general organic polymer inorganic non-metallic materials; thermal conductivity is smaller than that of the metal material; thermal conductivity of gaseous substances less than liquid substance, liquid solid material is less than. Therefore, the organic polymer material or amorphous inorganic material should be used as far as conditions permit, which is beneficial to thermal insulation. From the point of view of the material structure, when the apparent density of the material decreases, the porosity increases, and the pore inside the material is a large number of enclosed micro holes, the thermal conductivity of the material is relatively small. For foam plastics, the best apparent density is 16~40kg/m3 to meet the requirements of thermal insulation materials. Due to the existence of pores in the material in a humid environment, will inevitably be water, water and thermal conductivity (0.5815W/m - K) than ofstandstill air (0.0233W/m - K) is much larger, therefore, when the humidity increases, the equilibrium moisture content of materials increased, the thermal conductivity of materials will decrease. Therefore, as a thermal insulation material, the moisture absorption rate of the material itself should be as low as possible. If it is unavoidable, the material should be treated with water repellent or coated with waterproof material.

Q:What is the standard value of GRC durability?

The durability of the GRC standard value is actually not a strict labeling, usually measured in life, in the last century in 90s generally can be used for 20 years, and now can be used for 50 years, a few can be used for 70 years, 70 years it can be said with the same building life.

Q:How many useful years does the GRC art component have?

GRC components of the service life and its own quality and workmanship are related, quality and workmanship better, of course, the longer the use of the industry average is 30 years, there are 50-70 years of use.

Q:What is the standard of ASTM a283 GRC?

This is an American Standard. If you want to find a standard, you should recommend the best standard website I have ever used. It will help you find the standard you want. After all, it is an authoritative official website
