| At present, the resource utilization of construction waste and the research and application on the recycled concrete are still inchoate in China. Most of the research is concentrated on the basic properties of recycled aggregate and recycled concrete. But recycling of a large number of brick waste has not yet attracted enough attention. Only several institutions and units have done a preliminary study on the nature of the recycled brick concrete, but did not form a practical preparation of technique(hanjian,2013). And for the research of recycled brick concrete, mainly focuses on the preliminary study on mechanical properties of concrete, the study of the relationship between the type and the relation curve of little influence of various factors on the mechanical properties of concrete, especially in no detailed study for adding additive on the condition of concrete strength influence.In this paper, building demolition waste brick after two times of treatment after recycled brick aggregate is made, to replace all the concrete coarse aggregate. In reference to foreign experience at the same time, based on the domestic research status, focuses on the research of recycled brick aggregate of recycled brick aggregate was treated with reactive powder materials such as fly ash, silica fume,their effects on mechanical properties. To study the effect on the mechanical properties of concrete analysis of various factors, the optimal level of each factor draw the correlation curve and the strength of concrete is the main factor affecting the establishment of mathematical model, accurately, analyze the influencing factor son the mechanical properties of concrete, and find out the primary and secondary relation and influence factors.(1) the research of recycled brick aggregate size, design objective porosity, water cement ratio and other factors on the impact of Vegetation Ecology of recycled brick concrete strength, to determine the optimal levels of factors on the compressive strength, to determine the relationship between the compressive strength of recycled brick concrete target type and porosity of concrete.(2) relationship and the relationship between the study of the relationship between recycled brick concrete compressive strength and compressive strength and flexural strength.(3) the influence of addition of pushing vegetation ecological recycled brick concrete strength, to determine the best level of various factors on the compressive strength of recycled brick concrete, to determine the relationship between the type and the relationship curve of target porosity and compressive strength. |
