The Research Of Micro Silicon Powder And Air-entraining Water-reducing Agent On The Performance Of The Concrete

The durability of the concrete is the key factor of its working life and it is the widespread problem in the construction material industry. By means of adopting the method of controlling the percentage of water and cement in the concrete, changing the quantity of the micro silicon powder content, air-entraining water-reducing agent dose and the sand coarse aggregate ratio, the essay carries on research in the field of the quantity of air-containing in the concrete, the intensity of resisting compression of the concrete cube and the performance of the chlorine resistant ion in the concrete.Meanwhile, the essay,adopting the method of single factor function and orthogonal experiment, combining the method of materials mathematics and mathematical statistics, contrasts and analyzs the quantity of air-containing in the concrete, the intensity of resisting compression of the concrete cube and the performance of the chlorine resistant ion in the concrete under the function of the single factor and mutual function of many factors. When we put forward the interactive function of many factors, we cannot completely make the results of experiment under the function of the single factors as a guide to improve the performance of a certain kind of concrete. We must achieve the concrete design requirements through the specific analysis and repeated test when we have the specific circumstance. My experiment got the reasonable mix proportion under the interactive function of three factors, Therefore it has the certain reference value to the requirement to the configuration of the quantity of the air containing and the performance of penetration of anti-chloride ion. Meanwhile, I. put forward some prospects. I hope my essay can have some reference to the research of the durability of the concrete.
