Use A Concrete Slump Test To Be Sure The Concrete Pour Is Consistent
Anytime concrete is poured it should have a concrete slump test done to make sure that the consistency of the concrete is where it should be before the concrete is poured. This is a standard test that all those who work with concrete complete before they finish concrete trowel work and they allow the concrete to cure. The concrete slump test is to ensure that the mix portions are consistent throughout the mix. The only time this does not have to be done is when a no slump concrete is being used. No slump concrete still has its own testing but it is not as necessary as it is for those who are using the normal percentage of slump in their concrete mix.
There are many reasons why a concrete slump test is necessary. One of the main reasons is to test the consistency of the concrete. The consistency is important because it determines how easy the concrete is going to be worked. This means how easy the concrete it is to trowel and the ease with which the concrete can be finished. Mixing concrete in the correct ratios is therefore very important to ensure a consistent mix. When concrete is being poured, it is vibrated with a huge machine that creates a vibration, which moves the concrete into all the corners and deep areas of the frame. A slump test can tell how easy it is to compact the concrete in this way. This is also going to determine the time it is going to take for the concrete to cure completely.
It is not difficult to do a concrete slump test and there are only a few steps that need to be taken, and these only take a few items. Obviously you are going to need the concrete as well as a ruler, a pan to hold the concrete, a trowel, a steel rod and a slump cone. The steps to do the test are not very difficult. The first thing that needs to be done is the pan needs to have some moisture on it. It should not be dripping wet, but you do not want it dry either. Put concrete from the concrete mixer into the slump cone until it is one third full and then tamp down the concrete with the rod by banging the cone firmly on the ground. Do this in one third increments until it is full. The concrete should be very compact and should be leveled off when it is full. Turn the cone upside down and slowly lift the cone off of the concrete pile. You do not want the concrete to slide and it should hold the cone shape if the previous instructions were followed.
The concrete is going to slowly displace, when it has settled, it needs to be measured to see how much was displaced. This is going to show how wet or dry the concrete is. Concrete that is wet is going to slide more than dry concrete. Wet concrete is going to need more curing time and is going to be easier to work with. Dry concrete on the other hand is going to be harder to work with and is going to need less curing time.
