Product Principle1) Technology OrientationProduction and application of aerated concrete has a history more than 40 years in China. Viewing from technology point, high quality products can use 3mm special sand slurry technology to meet the construction requests and 50% energy saving goals. (When mortar joint is less than 3mm, take thermal conductivity coefficient of wall as 1; when mortar joint is more than 3mm, take thermal conductivity coefficient of wall as 1.5). Based on the history of the aerated concrete development, only high quality products can bring a prosperous market. Thus, the technology orientation of this scheme is high-class products according to China Standard GB11968-2006.2) Production CapacityIn our factory, the main production capacity is annually 50,000m3, 100,000m3, 150,000m3, 200,000m3, 300,000m3 etc. The product is aerated concrete block which is light in weight. Also, there is a reservation of plate in consideration of users' need.3) Product SpecificationProducts conform to requirement of 04~07 grade blocks stated in GB11968-2006.General Specifications of Aerated Concrete Blocks
