蒸压粉煤灰砖是指以粉煤灰、石灰或水泥为主要原料，掺加适量石膏和集料经混合料制备、压制成型、高压或常压养护或自然养护而成的粉煤灰砖。以粉煤灰、石灰为主要原料，掺加适量石膏和集料，经胚料制备、压制成型、高压蒸汽养护而成的，简称粉煤灰砖。
蒸压粉煤灰砖的抗压强度一般均较高,可达到20MPa或15MPa,至少可达到10MPa,能经受15次冻融循环的抗冻要求。另外,粉煤灰砖是一种有潜在活性的水硬性材料,在潮湿环境中能继续产生水化反应而使砖的内部结构更为密实,有利于强度的提高。
Zibo Linzi Luheng Building Material Co., Ltd. is affiliated to Shandong Pengxiang Group Co., Ltd. It was established on January 18, 2002 with a registered capital of 15 million yuan. It is located in Qilu Chemical Industrial Park, Zibo City, Shandong Province, covering an area of 100,000 square meters. The company has fixed assets of 120 million yuan, 350 employees, and currently has 600 production lines of 600,000 cubic meters of fly ash aerated concrete blocks, 100 million pieces of fly ash bricks and 1 million square meters of colored concrete pavement bricks, which were completed in 2003 and 2005 respectively. Put into production.
The main equipment of aerated concrete block production line has advanced level in China, with scientific design and reliable operation. The aerated concrete blocks produced by various specifications are made of siliceous materials and calcareous materials as raw materials, and are light-weight thermal insulation and heat-insulating materials made by processes such as compounding, pouring, gas expansion, cutting and curing. The aerated concrete block is light in weight, only 1/5 of the clay brick. The building with lower bearing capacity can simplify the foundation, improve the seismic resistance and reduce the building's own weight. Another main characteristic of aerated concrete blocks is low thermal conductivity, which is 1/4 of clay bricks. It has good thermal insulation and sound insulation performance, which can save building heating energy and increase the practical area, and because of its light weight, Large block shape can improve construction efficiency, shorten construction period and reduce project cost. It is widely used in industrial and civil buildings and has become the most prosperous wall material.
The fly ash standard brick production line is the most advanced fully automated production line in China. It has the characteristics of high automation and fast production speed. It is produced by batching, digestion, wheel milling, brick pressing and steam curing. Up to 100 million pieces. In May 2006, the product certification was obtained. The product has regular shape and size standard, and the compressive and flexural strengths are higher than two grades of red brick. There is no chemical residue and no radiation. It is a high-grade wall material for health and environmental protection.
Germany Martha's complete set of floor tiles production line, advanced technology, well-equipped, high degree of automation, production of a variety of high-intensity color paving slabs, curbstones, grass bricks, slope protection bricks, etc., in today's urban roads, plazas, reservoirs dominate The status is strongly promoted by the Ministry of Construction, the Ministry of Agriculture, the Ministry of Environmental Protection and governments at all levels.
