Is it true that the kelly ball test indicates if CLSM can support a person’s weight?

The statement that the kelly ball test indicates if Controlled Low Strength Material (CLSM) can support a person's weight is false. The kelly ball test is primarily designed to measure the workability or consistency of concrete and similar materials by assessing their resistance to penetration. It provides an indication of the material's relative stiffness or fluidity at the time of testing but does not directly measure strength or load-bearing capacity.

CLSM is typically designed with specific strength characteristics, and while the kelly ball test can give insights into the mixture's consistency, it does not provide the necessary information to evaluate whether the material can adequately support the weight of individuals or equipment. Factors such as the material's compressive strength, curing time, and mix design play a crucial role in its load-bearing capabilities, none of which are assessed by the kelly ball test. Thus, this test is not a suitable indicator for determining if CLSM can safely support a person’s weight.
