Admixture Of Water-stable Class Of Primary Research

In the last several decades, the international highway engineering attaches great importance to the problem of crack of semi-rigid base material, especially cement-stabilized aggregate. To solve the problem, this essay focuses on compound additive agent to improve semi-rigid base material performance of anti-crack. Compound additive agent as an excellent architectural material has been widely used in high performance cement field which has much similarity with cement-stabilized aggregate. A lot of research has been done to improve the performance of anti-crack of cement-stabilized aggregate by compound additive agent, but the level of compound additive agent scientific research is still resting on a primary phase .There is few project dealing with performance, technical characteristic and functionary mechanism of compound additive agent. In a word, it has luciferous foreground in the field of additive agent.This essay tries to improve the performance of mineral additive agent and compound many kinds of existing chemic additive agent. The scheme of this essay begins with research of reasonable dosage of additive agent, aims at improve the integrated performance of mixture by enhancing the performance of cement and sand slurry. The mixture design hold the gradation and cement proportion unchangeable, carry on research of performance of mixture based on the optimal content of additive agent and the analysis of microcosmic mechanism has been appended to. At last, this essay tries to find the relationship between additive agent and its performance, and gives a proposal about the most excellent additive agent which has a best behave of integrated performance.
