The Experimental Study Of Dula-fiber Concrete's Main Performance

The concrete's anti-frozen can reflect concrete's synthesis durability in the certain degree. This paper changed the former research mentality which enhanced concrete anti- frozen to use an extra material, aimed at the Inner Mongolian characteristic, utilized compound cement substituted ordinary Portland cement, mixed the Dula-fiber, the Grade 2 Inner Mongolian pulverized coal ash, the extra material that was highly effective reduces the quantity of water outside the concrete to improve the concrete's main performance, especially the concrete's anti- frozen. Followed this purpose, the paper used the orthogonal design method, combined the materials and the mathematical statistics knowledge, analyzed the range of intensity and anti-frozen as well as action mechanism contrastively under the single factor function and the multi-factors correlation. Proposed that when we mixed two or more extra materials into concrete, we cann't purely increase the quantity of the one to enhance some concrete's performances, which guided by the single factor function. On the contrary, we determined the quantity of this kind of extra material must by the conclusion of specific experiment under the multi-factors correlation. After that, as far as Inner mongolian area is concerned, gave a reasonable anti-frozen match ratio which is used in low intensity concrete contained three kinds of extra material in this experiment, consulted the quantity of Dula-fiber in Inner mongolia hydraulic engineering. Finally, the author proposed some prospects, and provided some references for the other reseachers.
