Introduction of non-burning block brick
Strength and service life of unfired block bricks and clay red bricks. Clay sintered bricks (260 x 170 x 56 mm) are generally numbered 75 to 100. The use of this technology to produce non-burning block bricks are strictly in accordance with the standard of 300 or above, the strength exceeds the national standard, the highest compressive strength can reach 35Mpa. Due to the pozzolanic activity of materials such as fly ash, calcium silicate hydrate and calcium aluminate gel are formed to fill the pores, which enhances the adhesion, promotes the long-term growth of strength and has good durability and corrosion resistance of the cured product. And stability. Both theory and practice have proved that its late strength is increasing and its service life is longer than that of clay bricks. For the cost of production, as long as there are various industrial waste residue resources such as fly ash, slag, coal gangue, sand, stone powder, slag, etc., which material is the most abundant and cheapest, the cost of producing bricks using this material is the lowest. . Since the production process is free from burning and steaming, the production cost is lower than the cost of the clay sintered brick. In addition, in order to vigorously promote new wall materials, China will implement tax exemption for non-burning block brick factories. For those who use clay bricks to build houses, a wall reform fund of 8 yuan per square meter will be levied to subsidize the new wall material factory. The cost difference is 16.58 yuan (actually, each piece of burn-free bricks and clay bricks has an advantage of 0.114 yuan before being sold).
Of course, brick pallets are indispensable in production, high quality, long service life and competitive price.
