APPENDIX — ST-45 PUMP SLUMPTEST PROCEDURE

1.To obtain a representative sample (concrete), take sev- eralsamplesatthreeormoreregularintervalsthroughout thedischargeofthemixerortruck.DONOTtakesamples at the beginning or end of the discharge.

2.Dampen the inside of the cone and place it on a smooth, moist, nonabsorbent, level surface large enough to ac- commodate both the slumped concrete and the slump cone. Stand on the “foot pieces” throughout the test procedure to hold the cone firmly in place.

3.Fill the cone 1/3 full by volume (Figure 41-A) and rod 25 timeswitha1/2”diax24”lg.bullet-pointedsteelrod.(This is a specific requirement which will produce non-stan- dard results unless followed exactly.) Distribute rodding evenly over the entire cross section of the sample.

4.Fill cone another 1/3 (Figure 41-B) which will make the cone 2/3 full by volume. Rod this second layer 25 times withtherodpenetratinginto,butnotthrough,thefirstlayer. Distribute rodding evenly over the entire cross section of the layer.

5.Fill cone to overflowing (Figure 41-C). Rod this layer 25 timeswithrodpenetratingintobutnotthrough,thesecond layer. Distribute rodding evenly over the entire cross section of this layer.

6.Remove the excess concrete (Figure 41-D) from the top of the cone, using the tamping rod as a screed.

7.Lift the cone vertically (Figure 41-E) with a slow even motion.DONOTjartheconcreteortilttheconeduringthis process.( Invert the withdrawn cone, and place it next to, but not touching the slumped concrete.

8.Lay a straight edge (Figure 41-F) across the top of the slumped cone. Measure the amount of slump in inches from the bottom of the straight edge to the top of the slumpedconcreteatapointovertheoriginalcenterofthe base .The slump operation must be complete in a maxi
