Abstract

This paper discussed the relationship between existing flowability test method and rheology test, and rheological flowable behaviour of Non Shrinkage Grouting Mortar(NSGM) based on rheological aspect. Five different grouting products are chosen and W/P are conformed to recommendation proposed by product company to meet KS F 4044. For rheological properties of NSGM, flowable behaviour can be explained by the assumption of Binghan model. Also, relationship between flowability test and rheology index of NSGM is confirmed based on this test. Increase of funneling time and decrease of flow led to increase rheology index.
