Fly ash of positive effect and negative effect to the applied technology of impact crusher concrete, generally more attention of impact crusher effect, often neglect the effect of impact crusher and the existence of negative effect. In particular, in accordance with the provisions of the code or specification of PF impact crusher concrete technology promotion, often know but not why. Powder, pulverized impact crusher, the impact crusher has always been a big problem, the basic principle, the basic effect of impact crusher effects in the hypothesis can help concrete workers fully understand the impact crusher concrete basic concepts and basic knowledge, to grasp the essence of Applied Technology of impact crusher concrete fundamentally and preparation of high quality powder ash concrete technology essentials, then in the whole production process of impact crusher concrete, positive effect in the development of impact crusher, while limiting the negative effect of impact crusher.In this way, can avoid the lack of understanding of the new technology of impact crusher concrete, or avoid confined to some historical, surface, local technical problems, make concentrate on trifles and neglect essentials fallacy, but through practice, obtains the actual effect. Especially the dynamic development to understand and grasp the positive and negative effects of impact crusher, helpful for the civil engineering technology broad from a development point of view, treat and handle the new impact crusher concrete technology is currently in development.
Composed of three basic effect of impact crusher effect analysis out, because of the nature and instinct of impact crusher, impact crusher and orderly degree, the quality of impact crusher concrete of impact crusher admixture and concrete engineering design and environment (including maintenance) and other factors, the occurrence of different degrees of positive and negative effect. But these three kinds of basic effect is related to each other and complement each other, because cross positive and negative effect, the result is a big change. Effect of impact crusher on the strength of concrete the main character, because the people are most concerned about is the strength index of the concrete performance, while the concrete quality, performance and rating (previously used label) is reflected through the strength index at home and abroad in the current specification. In fact, under certain conditions, the concrete hardening process and the strength of the hardened, exists very close relationship with other performance. So this is also so for impact crusher concrete, engineering and technical personnel, attaches great importance to the contrast, strength of impact crusher concrete with impact crusher in the base concrete and therefore, we must first understand the basic situation of the positive effect of impact crusher on concrete and negative effect.
