How to calculate the parameters of aerated concrete block process?

There is no formula for calculating the size, but there are two main specifications: one is: length: 600; height: 200, 250, 300; width: 75, 100, 125, 150, 175, 200, 250 ?(in increments of 25); length: 600; height: 240, 300 Other specifications can be negotiated between the purchasing unit and the production plant to determine the; width 60 Width: 60, 120, 180, 240 ? (in 60 increments). Brief introduction of aerated concrete: The concept of aerated concrete is a lightweight porous silicate product made of siliceous materials (sand, fly ash and silica-containing tailings, etc.) and calcareous materials (lime, cement) as the main raw materials, mixed with aerating agent (aluminum powder), through the batching, mixing, pouring, pre-cultivation, cutting, autoclaving, maintenance and other processes. Because it contains a large number of uniform and small pores after aerating, it is called aerated concrete. English: Autoclaved aerated concrete (AAC).

The following self-produced goods are exempted from the VAT policy:? Reclaimed water. Reclaimed water refers to water sources such as effluent from sewage treatment plants, industrial drainage (mine water), domestic sewage, and infiltration (filtration) liquids from garbage treatment plants, etc., which are recovered, treated appropriately to meet a certain standard of water quality and reused within a certain range of water resources. Recycled water should be in line with the Ministry of Water Resources "recycled water quality standards" (SL368-2006) of the relevant provisions of the ? Gum powder produced from waste tires as all the production of raw materials. Rubber powder should comply with the performance indicators specified in GB/T19208-2008.? Retreaded tires. Retreaded tires should comply with the performance indexes stipulated in GB7037-2007, GB14646-2007 or HG/T3979-2007, and the carcass of retreaded tires is 100% from waste tires. Production of raw materials mixed with waste residue proportion of not less than 30% of specific building materials. Specific building material products, namely bricks (excluding sintered common bricks), blocks, ceramic granules, wall panels, pipes, concrete, mortar, road manhole covers, road guardrails, fireproofing materials, fireproofing materials, thermal insulation materials, and mineral (rock) cotton. VAT exemption for sewage treatment labor. Sewage treatment refers to the business of processing and treating sewage to meet the water quality standards of the relevant provisions of GB18918-2002.
