 Abstract
Recently, it is more important to develop the environment-friendly binder as soil grouting materials for conforming to the government policy, "Green Growth". In this research, characteristic properties of gel time and homo gel strength of liquid chemical grouting materials for soil grouting using non-cement binder(NCB) were evaluated according to binder types, liquid B's W/B, liquid B's replacement ratio and the binder volume in order to estimate the applicable range of NCB as LW grouting materials. The test was performed using ordinary portland cement(OPC) as well as NCB1, NCB2, NCB3 which are environment-friendly inorganic binders developed by means of collaboration research by our company and which are different from chemical composition ratio each other. In conclusion, it was found that experimental estimated applicable range of binder volume is albe to a range of (NCB1), (NCB2), (NCB3) which is satisfied with the target gel time range(20~50sec.) and target homo gel strength range(more than 2MPa) in condition of (water temperature). And NCB could be applied to LW grouting materials and replace OPC, because NCB had the most excellent performance in certain section of gel time and homo gel strength in condition of this experiment.
