Great care needs to be taken in regards to the time spent on mixing the batch. It have to be neither extra nor a lot less than expected for comprehensive Mixing. In both situation, the quality of concrete will likely be effected adversely.
A slump test is used to find out the right hydration of the batch of concrete. The slump is the distance the soaked concrete settles after this post the slump cone is lifted off. The perfect mix won't be far too stiff or much too tender, but may have a slump of about 4".
Go on so as to add water as wanted and stroll around the perimeter on the pile, folding the mixture towards the centre and "chopping"
