Abstract

The purpose of this study is to develop a floor mortar construction technique which has high strength and inherent mechanical properties and does not cause cracks due to shrinkage after construction. It has been demonstrated that compressive strength, bending strength, flow with floor mortar, and crack reduction performance. As a result, it was confirmed that the developed floor mortar had the same or better performance comparing with the existing foreign products. The results of this experiment can be used as a validation material for high performance and high flowable mortar construction technology with excellent material performance, economical efficiency and construction ability by securing the required performance as floor mortar and selecting the optimal formulation.

본 연구는 고강도, 고유동의 성질을 갖고, 시공 후 수축현상이 저감되어 균열발생을 저감시킬 수 있는 바닥모르타르 배합선정에 관한 연구로서, 최적배합을 선정하기 위한 배합시험과 선정된 배합의 압축강도, 휨강도, 플로, 길이변화성능 및 염화물침투 저항성, 내화학성 등의 성능시험을 실시하였다. 시험결과, 유동성과 조기강도 발현이 가능하며, 수축저감을 통하여 균열발생 위험성을 개선시킬 수 있을 것이라 판단되는 배합을 선정하였으며, 선정된 배합은 자기수평모르타르 규격에 만족하는 성능을 확보하는 것으로 확인되었다. 본 연구의 결과를 통하여 우수한 재료성능과 경제성, 시공성을 갖는 고성능, 고유동의 바닥모르타르 시공기술을 확보할 예정이다.
