The concrete is in the flashing and marine hydraulic engineering to apply the most extensive engineering material, strength" is its the most important mechanics function, this is because the owner of any concrete construction want are all to in order to bear load or resist the every kind of function dint. Still request the concrete to have the other function on the engineering, such as the anti- permeability, anti-frozen ... etc.. But of these kinds and concrete strengths usually exsitses close contact. General to speak, and the concrete's strength is more high, rigid, anti- permeability, anti- frozen , resist the morals and custom with some erode to lie the ability of the quality too more high;0n the other hand, the strength is more high, and usually contraction too big, at the same time than frailty, easy crack .Therefore, usually assess to affect the degree's index sign with every kind of factor of quantity and evaluation of controling the concrete with concrete strength.But the anti- press the strength conduct and actions to divide the line the concrete to mark the number's standard. Aim at the esse that the problem, this text that building of northwest region concrete sufficient share profit to discard sliver ( coal- ore , powder ash from stove, slag ) resources with industry in Ningxia region, combination in addition superior match for silice powder for, at the same time in the concrete doping into first fixed amount, passing hand overing experimenting the design, macro view with micro view combine togethering, certainly fourth its ratio, the system have outed the work functioned to like of reunite the high and strong high performance concrete, and combine as to it's the strength and function proceeds research.Have to out to draw a conclusion:(1) according to hand over to experiment the bad analysis of squarethe result out:Water gum the ratio influence concrete 28 d strength influence high degree showed significance , in addition and coal- ore to concrete 28 d anti-s press strength affect showed significance , slag to concrete 28 d strengths had certainly.(2) pass to doping concrete the anti- press the strength test and analysis, and get this research superior collocation ratio that doping of the term bottom concrete is:A1B2C2D2E2, 28 d anti-s press the strength to 60. 4 Mpas.(3) The hydration process that doping-silice powder, powder ash from stove, whet the fien slag with the coal- ore on the other hand improved the grain class the collocated, on the other hand silice powder, powder ash from stove, slag is with the coal- ore entered the extent to become to with each other repair, from but make the doping- concrete performance the export superposition with each other repair the effect.(4) high performance concrete is a kind of many sets the superposition for cent reuniting the material, each cent function add even the superposition add the effect performance very and obviously. Therefore, the eligibility use more than two minerals-doping to plus more than two in additions dopings to add at the same time, with the further improvement function with obtain a certain characteristic. (60)This experiments four kinds of minerals of a dopings to add two kinds of in additions to get the good result at the same time.The research of that item, since increased the concrete's strength and enduring the function, and again make use ofed the large quantity's wasted, and lower the engineering to build the priced, and protect the ecosystem environment. Still alleviated at the same time western region bigness request towards resources, energy of big development. Therefore, the research of that item with expand to have got the extensive theories with actual application value, can't economic performance that estimate with social performance. |
