Experiment research about basic mechanics function of reinforced dry—mixing self-compacting concrete simple beams ABSTRACT Dry—mixing self-compacting concrete is a kind of concrete that has property of high flowing，self-compacting and tiny inflation．In the house reinforcing and reformation engineering，dry—mixing self-compacting content has been gradually used to build new beams，planks，pillars actually．But the concerning dry-mixing self-compacting concrete anticipates the members to be subjected to the dint transforms function，etc．still lacks system of research．Dry—mixing self-compacting concrete has a lot of advantages，in order to expand dry-mixing self-compacting concrete，this article studies in different mix proportions，property of dry—mixing self-compacting concrete such as dissimilarity to go together with a ratio stem under circumstance mix the standard of the high performance concrete to try a piece of anti to the compressivestrength，pulledstrength，the prismatic strength，glue knot function between dry—mixing self-compacting concrete and reinforcing bar．1 5reinforced dry—mixing self-compacting concrete simple beams under circumstances，three kinds of different mix proportions，different category of reinforcing steel bar，three average points to add loud，load—deflection curves function，the normal cross sectional strength properties，the effects of the shear—span to depth ratio on the shear capacity，dinting transform curve，the developing regulation of crack，connect dint performance of blast load reinforcing steel bar and dry—mixing self-compacting concrete，the contingency of the concrete development regulation and normal usage and load the dint extreme limit breakage appearance．Providing the basis of science for the design and construction of dry-mixing self-compacting content main result is as follows： (1)To known about the basic mechanics function of reinforcing steel dry—mixing self-compacting concrete，dry—mixing self-compacting content the normal cross sectional
