Slump values for different grades of concrete
Webb23 feb. 2024 · In this study, the slump values per unit AD content (slump to AD ratio, slump/AD ratio) of all the concrete mixtures were calculated and compared. Based on our observations, we determined that high slump/AD ratios can maximize the fluidity improvement effect of the AD in a concrete mix, indicating that such conditions are … Webb10 jan. 2024 · The concrete slump test results are interpreted using Table B.1 of BS 8500 as shown below. There are 5 consistency classes, ranging from S1 to S5. Concrete consistency class S4 and S5 have high slump values (high water cement ratio), which can lead to segregation of the aggregates and cement.
