The raw material of autoclaved lime-sand brick is mainly sand. Promoting autoclaved lime-sand brick to replace clay brick has a positive effect on reducing environmental pollution, protecting farmland and improving building functions. The performance of autoclaved lime-sand brick is analyzed and studied, the problems existing in the application of autoclaved lime-sand brick are discussed, and the technical measures that should be taken in design and construction are put forward.
Zhejiang Wuyi Shenlong Flotation Co., Ltd. Building Materials Branch has completed the approval procedures for the production line of 150000 cubic meters of aerated concrete blocks and 60 million standard brick autoclaved bricks, implemented the requirements of "three simultaneities" for environmental protection, basically completed the acceptance data, and completed the environmental protection measures in accordance with the requirements of the environmental assessment and registration form filing documents, and basically established various environmental protection management systems, The main pollutant indicators meet the requirements of the corresponding pollutant discharge standards, meet the requirements of the environmental assessment and registration form filing documents, and the environmental protection facilities of the project are accepted without the unqualified conditions specified in the Interim Measures for Environmental Protection Acceptance of Completed Construction Projects (GHGHGHP  No. 4).
