Cement clinker utilization durability analysis
Improve the production and quality of ordinary cement At present, China's cement consumption reaches billions of tons or more, and most of this total cement output is achieved by shaft kilns. The quality of cement clinker that is calcined in this kiln is unstable, and it is difficult to wear and waste. Resources and energy and pollute the environment are very serious. The current improvement in the quality and marking of cement is mainly achieved by increasing the quality of cement clinker, showing its advantages and disadvantages. After adopting this system, one can prevent the width of the cement mill from discharging, secondly, the secondary addition of industrial waste can be carried out in the system, and the third can be added three times in the preparation of concrete, so as to reduce the power consumption and increase the output of cement production. the goal of.
In this cement system, the amount of industrial waste residue is 50%, of which the proportion of fly ash in the waste residue is more than 40%, and the strength grade reaches 42.5MPa, which has reached the international advanced level. At present, the use of ordinary Portland cement for the preparation of low-ion permeability, sulfate-resistant erosion cement, etc. is being carried out. The development of low-cost, high-performance concrete in the development of industrial fly ash, slag and other industrial waste residue activity will inevitably increase its mix in the cement and concrete systems, that is, to achieve the purpose of reducing the amount of cement in the uni-side concrete. At the same time, due to the reduction of the amount of ordinary Portland cement, a series of durability problems of concrete is improved, achieving the goal of low cost and high performance. For example, in the western transportation science and technology project of our hospital, the use of high-quality fly ash and slag double-blend technology to formulate underwater non-dispersed and self-compacting concrete has better working characteristics, achieves appropriate strength and significantly enhances resistance to chloride ion penetration. Effectively inhibit corrosion of steel bars, and have good adaptability to flocculants, water-reducing agents, etc.
