Structure of hole and the hole of aerated concrete wall. The volume density of aerated concrete 500kg/m3, the void content is about the concrete volume cement equipment of 50%, the remaining 50% is between the hole wall. Hole is made of aluminium powder in slurry gas formation, and in the hardening process is fixed in the concrete, aperture within 2mm, the general is 0.2 ~ 0.8mm. Hole wall is basic material of aerated concrete equipment under the action of water, artificial stone formation after autoclaved curing after. It is composed of hydration products, not the hydration of the material particles and mixed water formation pore. Obviously, aerated concrete strength and other physical mechanical properties depends on the structure and intensity of the partition wall: hole; hole shape, aperture, porosity content and distribution uniformity. Aerated concrete hole wall structure: 1, unreacted material particles For Portland concrete, cannot say the hydration reaction is more complete, hydration products and more, the strength of concrete is higher. With a certain amount of unreacted particles form the skeleton, hydration products as cementing material, wrapped in the unreacted particles surface and fill the gap of concrete, its strength and other physical and mechanical performance of the best. 2, the hole of the pores in the JianbiAerated Lightweight Brick Machine Light Weight Block Machine Hole wall within the pore structure of the main raw materials and water ratio and degree of hydration reaction. Generally speaking, according to Ore Processing Equipmentthe size of the pores can be roughly divided into water transitions between the holes of cementing hole, product within the pores and between the two. The smaller pore sizes of hydration products within the aperture, generally aac lineless than 50; the pores are the raw material -- water was not hydration products filled the space with water, this type of pore size is relatively large, the aperture is generally greaterMineral Processing Equipment than 2000. Between the two types of pore, wbenefaction machinehich we call the transition hole. Effects of size and porosity diameter on concrete strength is greater, but the aerated concrete is a porous Flotatorstructure, relatively speaking, the hole wall of the pores in the influence on the Fu cover than pore structure influence on the strength of large. 3, the hydration products The hydration products of aerated concrete equipment and similar general silicate concrete. The fly ash aerated concrete as an example
