The silicate lightweight high-strength building structure ceramsite (light aggregate) developed by the company adopts a new non-burning autoclave process. Most of the appearance features a round sphere, the color is grayish black, with light weight, high strength and insulation. Excellent performance such as heat, sound-absorbing and sound-proof, fire-resistant and anti-vibration, anti-seepage and anti-freezing. Light weight (high specific strength): The density is about half of that of ordinary gravel. Compared with gravel concrete, the weight is about 20% lighter. Transportation handling burden. Insulation: Due to the internal network criss-cross, the concrete with which it is configured has a thermal conductivity 1-2 times lower than that of ordinary concrete. Refractory and anti-vibration: The fire resistance is more than 4 times that of ordinary concrete; for the same fire-resistant period, the thickness of the sheet is 20% thin. Due to its light weight, low modulus of elasticity and good resistance to deformation, it has better shock resistance. Applied to the fields of fabricated buildings, PC components, traffic pavement, high-speed rail, elevated bridges, etc., its main technical indicators have reached or exceeded the level of domestic and international similar products.
