성화돈 ( Sung Hwa-don ),황의성 ( Hwang Yi-sung ),천병식 ( Chun Byung-sik ) 한국구조물진단유지관리공학회 2007 한국구조물진단유지관리공학회 학술발표대회 논문집 Vol.11 No.1
Portland cement and sodium silicate are widely used as the main components of the injection, which are used to prevent flow and improve ground condition. The main problem of the injection material is the leaching of the sodium hydroxite and silicate due to the limited reaction with the cement. In this paper, the effect of cement dydration retarder on the compressive strength of the sodium silicate - cement gel was studied. A series of tests, including digital-type testing machine, X-ray diffraction and scanning electron microscope were performed. Results were clearly demonstrated that the sodium tripolyphosphate(STPP), which was the cement hydration retarder in the test, significantly improved the initial strength of the homogel.
