Limestone powder can cause the thaumasite form of sulfate attack (TSA) of cementbased materials, but the relationship between the content of limestone powder and the degree of TSA is unclear. Hence, six different contents of limestone powder (0%, 5%, 10%, 15%, 30%, and 45%) were used to study the effect of the limestone powder content on the TSA of cementbased materials according to ...

In the study, limestone dust was fixed at 9%, and expansive soil was replaced with fly ash by (5%, 10%, 15%, and 20%). According to the results, 15% of fly with 9% of limestone dust can be used for stabilization of such high expansive soil. Ogila [ 11] studied the effect of adding limestone dust (passing sieve #200) to very high expansive soils.

Limestone can be used in pigmentmaking and as a filler for more expensive paints. Paper is also manufactured using limestone. Wood is treated with acid to help break it down, which is then treated with limestone to neutralize the acid and whiten paper. Limestone is also used in dyes and carpeting or other floor coverings, such as protective ...
