Analysis on Production Technology of Non-burning Standard Bricks



In order to further implement the “10th Five-Year Plan” for wall material innovation and the notice requirements of the General Office of the State Council for further promoting the renovation of wall materials and the promotion of energy-efficient buildings in September 2005, it is necessary to increase the number of new wall bodies for the production of solid clay bricks. In order to promote the application of materials, it is necessary to actively use local resources to develop new wall material products that are low in energy consumption, low in pollution, high in performance, high in strength, multi-functional, serialized, and capable of improving construction efficiency.



The cement-free brick machine protects the land, saves energy, and utilizes local mineral resources, waste, etc., to produce all kinds of non-burnt bricks and blocks, and to supply different levels of public buildings and residential buildings. Its products have wide sources of raw materials, low investment, quick effect, good efficiency, fast construction speed and low cost. They have broad development prospects.



First, raw materials:



Cement, fly ash, tailings sand, shale, red mud, boron mud, phosphogypsum slag, quicklime, ordinary sand, stone chips, natural coal gangue, volcanic slag, pumice, slag, admixture, etc.



Second, product specifications:



The size of the non-burning brick is 240×115×53 (mm), and other block products of different specifications can be produced according to user requirements.



Third, product performance:



The compressive strength of the non-burned bricks shall comply with the national standard GB5101-2003, and the grade is MU10-MU30.



Fourth, equipment investment and output:
