Problems that should be paid attention to in the winter production of ordinary concrete bricks Date: August 21, 2011 14:17 Due to the low temperature in winter, it is not conducive to the production and maintenance of ordinary concrete bricks, and the finished products are susceptible to freezing damage, affecting product quality. Therefore, the production of ordinary concrete bricks in winter should pay special attention to the following aspects: 1. Winter production measures should be reasonable, and technical personnel should be trained in winter production technology. At the same time, do a good job of anti-skid and anti-freezing to ensure safe production. 2. The materials used in the production of concrete bricks should avoid freezing. Sand, gravel, fly ash and other materials should be mixed with the use, do not accumulate

Due to the low temperature in winter, it is not conducive to the production and maintenance of ordinary concrete bricks, and the finished products are easily damaged by freezing, which affects product quality. Therefore, the production of ordinary concrete bricks in winter should pay special attention to the following aspects: 1. Winter production measures should be reasonable, and technical personnel should be trained in winter production technology. At the same time, do a good job of anti-skid and anti-freezing to ensure safe production. 2. The materials used in the production of concrete bricks should avoid freezing. Sand, gravel, fly ash and other materials should be mixed with use, do not accumulate too much. Warm water shall be used for mixing to prevent ice, snow and frozen blocks from entering the mixer and affecting the quality of bricks. 3. The temperature is too low will directly affect the quality of concrete bricks, mixing to add appropriate additives (antifreeze), do not have the conditions to stop production. 4. The finished bricks must be covered with moisturizing materials. When the temperature is lower than 0°C, the raw materials and finished products shall be kept warm. The curing time shall not be less than 45 days. The strength test must be done before use. The storage of various materials and the placement of finished products on site shall be regulated. Bricks that are frozen after soaking in water cannot be used.
