Consolidating stiff concrete sample

Slower setting time and strength gain of concrete during cold weather typically delays finishing operations and form removal.Chemical admixtures and other modifications to the concrete mixture can accelerate the rate of setting and strength gain.

In a slump test, concrete is tamped into a cone, which is then removed to see how far the concrete sinks or slumps without the support of the cone.The concrete had all tests run before adding the Super P, air tested ok, slump was routinely low.These results were documented, the Super P was added, and no additional testing was performed before it was poured. We're going under the assumption that the addtion of the Super P would pretty much invalidate any slump test anyways, but we're looking for some evidence or section of code that confirms or refutes this process of running no further tests after the plasticizer is added (break tests were all coming back good).Concrete is an artificial conglomerate stone made essentially of Portland cement, water, and aggregates.When first mixed the water and cement constitute a paste which surrounds all the individual pieces of aggregate to make a plastic mixture.
