Q:What are the new energy-saving building materials? What's new?
As far as its varieties are concerned, the new wall materials mainly include bricks, blocks and slabs, such as clay hollow bricks, waste clay bricks, non clay bricks, building blocks, aerated concrete, light plates and composite boards.
Q:Calcium silicate board for house ceiling, 6mm or 8mm?
The calcium silicate board will not have the above shortcomings, the thickness of 15mm if it is the calcium silicate board 4mm ceiling 600*600 thickness can reach the effect of the biggest advantages of mineral wool board, calcium silicate board also is not a burning fire, moisture absorption is very good, green building materials.
Q:What is dew point of thermal insulation material?
Thermal insulation materials are generally used to guide heat coefficient less than or equal to 0.2 of the material. Thermal insulation material development is very fast, and in industry and building the use of good insulation technology and materials, often can get twice the result with half the effort. Each ton of mineral cotton insulation used in the building saves one ton of oil a year.
Q:Eterpan and yinte in what is the difference?
Calcium silicate board:Calcium silicate board is mainly inorganic mineral fiber or cellulose fiber and other loose short fiber materials with siliceous and calcareous materials as the main cementing material, pulping, molding, in high temperature and high pressure saturated steam curing acceleration, sheet formation of calcium silicate gel made.Calcium silicate board is a new type of building and industrial plate with excellent properties. Its products are fireproof, moisture-proof, soundproof, moth resistant and durable. It is an ideal decorative board for ceiling and partition. Excellent waterproof performance, just can prevent the home improvement for a long time damp deformation, especially in the bathroom for a long time in a humid environment, the use of calcium silicate board ceiling is the best choice.
Q:What's the use of white portland cement?
The typical feature of white cement is high whiteness, with bright color, generally used for a variety of architectural decoration materials, painting, sculpture, a typical floor, terrazzo, white cement can be used to produce white and colored concrete, is the largest cement production decoration.
Q:What are the three major effects of fly ash in concrete?
The "form effect" of fly ash contains many glass beads, the surface is smooth and the texture is dense. It is this form to water reducing effect, compact and homogeneous effect, can promote the early hydration of cement flocculation effect of solution, change the mixture rheological properties, the initial structure and hardening of the various functions, especially for pumping concrete, can play a good role in lubrication.
Q:What are the main use of lime?
Lime milk and mortar, slaked lime or lime paste, with lots of paint. Lime mortar or slaked lime powder can be used to prepare lime mortar or cement lime mixture mortar for masonry or plastering engineering.
Q:Calcium silicate board white ICI belongs to wood surface paint?
No, it isn't。Calcium silicate board material properties should be comparable with cement products, usually referred to as cement board is actually calcium silicate board.
Q:Eterpan with calcium silicate is sold on the market are the same thing? Non asbestos calcium silicate board is Eterpan it
Aitken is a brand of non asbestos calcium silicate board is a product name
Q:What is the main role of fly ash added in concrete products?
The workability of fresh concrete can be improved by adding fly ashThe workability of fresh concrete is affected by the volume, water cement ratio, gradation, shape and porosity of the aggregate. The fly ash is used for fresh concrete is the obvious benefits of increasing the slurry volume, slurry filled with aggregate between pores, inclusions and lubrication of aggregate particles, so that the concrete mixture has better cohesiveness and plasticity. The aggregate particles of fly ash can reduce the interfacial friction between the paste and aggregate, and improve the workability of the concrete mixture at the contact point of the aggregate.
