The penetrability of microfine cement Rheocem 900 with Rheobuild 2000 PF additivies to sand samples having various gradations

In this study, the experimental groutability study carried out with injection material (Rheocem 900), which was prepaired using plasticizer (Rheobuild 2000 PF) and microfine cement, on various sand gradation (fine-medium-coarse) to investigate plasticizers, probable negative or positive effects on microfine cements grouts. First of all, experimental study started by finding the rheological properties of suspensions prepaired using plasticizer and have different W/C ratios. At the and of the studies significant changes was observed on the rheological properties of suspensions which is prepaired using plasticizer. In terms of setting time, stability and viscosity the suspensions which are prepaired using plasticizer was put forth more positive results than the suspensions without additivies. After clearifying of rheological properties, the grout process with different pressure was applicated to the sand sample, which were prepaired by various gradation. The injection material prepaired using plasticizer were performed succesfully at the low pressures to the sand samples which include more fine grained sand. On the specimens grouted succesfully, strength and permeability experiments was carried out. At the end of 24 hours it was observed that all the specimens was impermeable. Using plastisizer on grouting doesn?t effect the final unconfined compression strength results.
