Problems solved by technology

[0002] With the rapid development of the national economy and the continuous improvement of people's living standards, the consumption of energy is also increasing, and the problem of energy shortage is becoming more and more prominent. One of them is widely used. Usually, energy-saving bricks are made of Portland cement, sludge, gypsum, slag and industrial waste. The cost of raw materials is low, but the sintering temperature required in the preparation process is relatively high. High, often above 1000°C, or even higher, and the cost of energy consumption is high. The main problem is that the existing energy-saving bricks are difficult to meet the requirements of both thermal insulation and physical and chemical properties. Poor, or insufficient mechanical strength, etc., seriously affect the applicability, reliability and safety of energy-saving bricks in construction projects
