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.
