Abstract

The study measures the effect of domestic kaolin on the compressive strength of cement mortar and light weight porous concrete. The kaolin was thermally treated in an electric furnace at T=800℃ for a pozzolan reaction. Cement mortar and light weight porous concrete were used to compare the effect of adding meta-kaolin (0%～30%). As a result, mixture with 10%～15% meta-kaolin obtained the highest compressive strength. The tests were also applied to investigate the effect of a meta-kaolin particle size in light weight porous concrete. The mixtures were made by replacing cement with 15% meta-kaolin while varying the particle size of meta-kaolin. The lightweight porous concrete with 38～48 um meta-kaolin in 15% replacement develops 100% higher compressive strength than no addition of meta-kaolin.

이 연구에서는 국내산 고령토를 활용한 포졸란 반응을 통해 시멘트모르타르 및 경량기포콘크리트의 압축강도에 대한 효과를 확인하였다. 포졸란 반응을 위해 고령토를 800℃에서 열처리한 메타카올린을 시멘트모르타르와 경량기포콘크리트에 첨가한 결과 10～15%를 첨가할 경우 압축강도가 가장 우수하였다. 또한 메타카올린의 입도에 따른 압축강도를 측정해 본 결과 35～44 um 크기의 메타카올린을 15% 첨가할 경우 메타카올린을 첨가하지 않은 경우에 비해 압축강도가 100% 이상 크게 향상되었다.
