Effect of Conditioning on Soil Workability determined by Mini-Slump and Flow Table Tests

Abstract: Effect of conditioning parameters on workability of sands was investigated by using flow table and newly suggested mini slump tests. The soil conditioning tests were performed on standard mortar sand at two foam types and different Foam Expansion Ratio () and Foam Injection Ratio () values. The foams were characterized by measurements of stability (half-life), density and bubble size. The results indicated that the mini slump test results had strong relationships with and density and half-life. The effect of the bubble size measured under atmospheric pressure on workability seemed to be limited, although it was strongly related to and foam type. Mini slump test reduced the required soil amount by around 1/10th compared to the regular slump tests, and might be a cheaper, faster and simpler way of determining workability.
