WebbThe slump test to BS 1881: Part 102/BS EN 12350-2 and the flow table test to BS 1881: Part 105/BS EN 12350-5 involve measurement of the concrete when deformation under a reducing stress has ceased. They are thereby an inverse measure of the yield value of concrete – i.e. the higher the consistence class, the lower the yield value. photorescue chiphttp://www.civilology.com/concrete-slump-test/ how much are trampolinesWebbconcrete test Target values Weights 1 Y 1 Slump flow (cm) Fresh concrete test Larger is better 1 2 Y 2 Compressive strength (N/mm2) 28 days Hardened concrete test Larger is better 1 The mixtures were prepared approximately in 4 min using a rotating planetary mixer.
