The production process of polystyrene concrete blocks produced using industrial waste residues includes the following steps:
Step 1: Foaming: dilute the foaming agent with tap water at a ratio of 1:40, add it to the foaming tank after dilution, use an air compressor to pass compressed air into the foaming tank, and stir the foaming agent with compressed air to form foam with a bubble diameter of ≤1mm for standby use;
Step 2: Slurrying, pouring, and pre-curing: ordinary silicate cement, high-performance concrete mineral admixtures, polystyrene particles, alkali-resistant short-cut anti-cracking reinforcing fibers in the polystyrene concrete block slurry formula , high-efficiency dispersant and other raw materials are accurately measured by the microcomputer batching system in proportion, added to the forced double-shaft mixer for stirring, stirred for nearly two minutes, added foam and stirred for another minute, the slurry is evenly poured into the pre-prepared mold, scraped flat, and placed in the steam pre-curing room for homogenization and curing;
Step 3: Demolding, steam curing Demolding after 3 to 4 hours of pre-curing, and entering the steam curing room for steam curing after demolding; Note: Demolding can use high-grade fatty acid water-based isolation agent, and usually demolding isolation agent can also use waste oil.
Step 4: Cutting, stacking, packaging, inspection After steam curing, the block body reaches strength and enters the automatic circular saw cutting line, where it is cut according to the required size. The cut blocks are stacked and packaged into the warehouse through automatic stacking, and the finished product can be obtained after passing the inspection.
The polystyrene concrete blocks produced by the polystyrene concrete block process formula have low production costs and are significantly lighter than traditional bricks. The mechanical properties can reach the strength index of autoclaved aerated concrete blocks. The construction of the blocks is simple and quick, and industrial waste residue is used as raw materials to achieve an energy-saving standard of 65% for walls. The use of the blocks can improve the fire resistance and service life of the wall.
