Engineering Properties of Low Cement Mortar with type and Various Incorporating Ratios of Setting Accelerator

응결촉진제 종류 및 치환율 변화에 따른 저시멘트 모르타르의 공학적 특성

In this research it was attempted to analyze the general engineering properties of low cement mortar according to the type of setting accelerator and substitution rate, when 1% substitution rate for setting accelerator was used a high rate of compressive strength manifestation was shown and that the WS-10 type setting accelerator was appropriate. For the rate of change of length, when 3% substitution rate for setting accelerator was used, it was shown that due to initial expansion the shrinkage compensation was not significant, and when taking into consideration strength and shrinkage, 1% of WS-10 was shown to be appropriate.
