다당계 균주를 혼입한 고기능성 콘크리트 제반특성에 관한 연구

Abstract

The purpose of this study is to figure out the impact of the properties of concrete including cultivated strain, which can increase concrete filling without additional vibratory compaction and prevent segregation as a matter related to especially high flow concrete among the various properties of concrete mixtures. We can make eco-friendly concrete by reducing toxicity to cause the sick house syndrome by using it as a mixture to improve concrete properties, because polysaccharide strain have been known harmless to the human body. Therefore, This study confirmed the difference between the existing plain concrete and it, after analyzing physical and mechanical properties of concrete containing the polysaccharide strain. As a result, concrete which mixed the polysaccharide strain had 13-81% higher compressive strength and lower shrinkage than plain concrete, its durability also was shown good results.
