Effect of pore size distribution on the qualities of recycled aggregate concrete
In this study, the pore volume of 2μm∼100 μm and the pore volume of 50 nm∼2μm of new mortar in recycled aggregate concrete were inclined to increase by affecting the porosity of adhered mortar. The qualities of concrete with a high porosity recycled aggregate were deteriorated in comparison with general concrete. On the other hand, the pore volume of 50 nm∼2μm of recycled aggregate concrete with metakolin (MK) and silica fume(SF) were a little reduced and the pore volume of 6 nm∼50 nm was greatly increased more than that of concrete without MK and SF. The qualities of recycled aggregate concrete were improved for using MK and SF regarding on compressive strength, absorption and penetrated resistance of chloride ion. Furthermore, the compressive strength, the absorption value and the passed charge of chloride ion of recycled aggregate concrete were a good correlation with the pore volume of 50 nm∼2μm of new mortar.
