Answer Posted / harshal .s. khode
A slump test is a method used to determine the consistency
of concrete. The consistency, or stiffness, indicates how
much water has been used in the mix. The stiffness of the
concrete mix should be matched to the requirements for the
finished product.
All concrete is a combination of aggregate (gravel and/or
sand), cement, and water, but the proportions of the mix
can be varied. A larger proportion of water causes a
softer, wet concrete mix, which is easier to handle during
the pour and requires less care during curing. It also
results in a slightly softer and less durable finished
product. A smaller amount of water causes a stiffer, wet
concrete mix, which is harder to manage but makes a
stronger and more durable finished product, one with a
higher concrete pounds per square inch (PSI).
