In addition to that, crushed rocks normally have more fine particles. With crushed granite rocks large amounts of flaky free mica in the fine fractions is common and leads to problems with workability. The main

Impact of crushed limestone dust on concrete’s properties

2021-1-1  The use of crushed limestone dust may affect the properties of concrete. As per Celik and Marar the inherent property of concrete to flow known as workability decreases with the use of crushed limestone dust. This is due to the presence of finer particles whose specific surface area is high, which absorbs more water and leads to a reduction in slump value.

Impact of crushed limestone dust on concrete’s properties

Abstract The construction industry has developed at the pace as human race. With time many materials were developed to be used in construction. Among all the materials concrete has been tested, researched and used for almost every type of construction. Sand is a basic component of concrete. With increase in concrete production and usage the sand dredging also increased at an alarming rate.
