What is the cellural lightweight concrete(clc)?
clc is the cellural lightweight concrete. It’s made by physical methods of foam, and by the sand or other similar material, cement and water mixing slurry after even mixing and form a fluid of building materials.
Will this material for casting molding box, and then after room temperature curing and late cutting processing, it can be made a variety of specifications of the building materials products.
cellural lightweight concrete(clc) performance advantages
CLC products have low water absorption rate, high freeze-thaw resistance index, good thermal and acoustic insulation effect, high fireproof rating, strength index up to 20 MPa, and bulk density range of 100-1600 kg/m3; It can be used as load-bearing material and can be used as filling material; it can be used for interior wall partitioning and exterior wall masonry; it can also be used as roofing and roofing materials.
CLC is an environmentally friendly building material that saves energy and reduces consumption: in the production process, it has the characteristics of eliminating high temperature and high pressure steaming and steel bar anti-rust treatment, one-time casting molding, saving productive resources (such as raw materials, coal, electricity, etc.); In the construction application, it also saves the masonry mortar, saves the internal and external wall hanging plaster, saves the masonry time, saves the additional insulation materials (such as polystyrene board, mineral wool, etc.), and can be sawed, cut, planed, drilled, nailed, Advantages of sticking; in residential use, due to the unique thermal insulation performance of CLC, it can achieve more than 65% of building energy-saving effects, save a lot of coal and electricity resources, and facilitate life.
The materials of make cellural lightweight concrete(clc)
CLC is the main raw materials of sand, cement, water, and a small amount of additives, or trace need to use lime, gypsum, etc.;
Also can use part of the industrial wastes such as fly ash, slag, slag, etc. For ordinary (washed) sand, sand particle size depending on the product density is 0, respectively. 05 ~ 4 mm. Production of filler material, generally for less than 2 mm, having been fine grinding; Cement for ordinary Portland cement.
CLC products from the specification plate, block and non-standard products three series, the plank can join reinforced or fiber material in order to improve the compressive strength and bending strength. Each series of products have a variety of sizes. Of course, can also according to the market and users need to production of non-standard products; In addition, can also be in the construction site at any time into required size and shape
Cellular lightweight concrete(clc) manufacturing process
Determine the physical composition of the material and CLC and product performance indicators -------Select the appropriate material mix ratio-----Raw material ratio and measurement-----Mixture stirring-----CLC material finished canning or injection molding------Product maintenance----Product release and stop-----Upper thread cutting----Products pallet packaging----Storage area to store and factory
Cellular lightweight concrete(clc) Application
It is applied to the composite wall structure: at this point, the CLC is made into 600 x 400 x plate (50 ~ 200) mm, cooperate with the other as the main wall materials, such as porous concrete products (AAC plate or block) or clay hollow brick, lime-sand brick, etc., eventually form a composite insulated wall. Sierra group, for instance, Germany is a factory production of low density, low strength, low thermal conductivity of the plate, the German standard plate specifications, the density of 120 kg/m3, strength 0.35 MPa, the coefficient of thermal conductivity of 0. 045 w/(m • K), bibulous rate is lower than 0. 6%.
This material is widely used in:
1 Roof insulation layer: the same foam concrete grout plus adhesive, the material is directly laid on the roof, and then surface treatment and coating;
2 Inner and outer wall insulation wall surface: After the main wall is completed, the CLC strip is attached or externally attached to the inner wall or the outer wall surface, and then the surface treatment of the wall surface is performed.
3 Load-bearing or non-load-bearing wall of a single wall
The dry density of ceramsite foamed cement self-insulating block can be more than 5.0mpa, which can be used as non-load-bearing wall. Ceramsite foamed cement self-insulating block can also be designed and constructed according to the standard of load-bearing wall.
4 Space filling
Because of CLC have good fluid properties and lower shear force, it is widely used for pipe, casing, the well hole hollow, mines and other objects in the low price of filler material
5 Masonry or wall reflection
6 Indoor floor insulation and sound insulation layer cast-in-place :
Especially suitable for floor heating buildings, the CLC is directly poured on the ground, and then the heating system and protective layer are laid, which can prevent the downward propagation of heat energy and achieve the sound insulation effect between floors.
7 Road construction: In road construction, CLC can be used as a subgrade instead of or in addition to stone.
8 ClC for vegetable insulation greenhouse construction Lightweight concrete has its special insulation properties, so it is especially good for building large boron.
