강도 및 건조수축 저감을 통한 CLC의 안정성 평가
Evaluation of Stability of CLC through Strength and Reduction of Drying Shrinkage
- 발행 : 2022.11.10
초록
This study intends to conduct tests on subsidence and drying shrinkage by mixing CaO-CSA expansion materials to ensure the stability of CLC, and to understand its properties. Based on CLC of 0.6, the replacement ratio of CaO-CSA expansion material was conducted at five levels compared to blast furnace slag, and the results are as follows. The replacement of CaO-CSA expansion material at an appropriate level produces ethringhite and potassium hydroxide, and it is believed that the internal voids of CLC and the Tobelmorite interlayer structure are charged to increase the structural stability, leading to an increase in compressive strength and a decrease in the drying shrinkage. However, it is judged that tissue relaxation due to excessive substances in the high replacement ratio affects the stability of CLC. In the future, we will conduct additional experiments on density, absorption rate, flow test, and settlement, and evaluate and analyze the stability of CLC by selecting the optimal replacement ratio of CaO-CSA expansion materials.
