Beneficial use of limestone filler with calcium

Limestone filler was progressively added to the cement as calcite, replacing the inert quartz filler. To simplify the calculation, the limestone filler was considered to be composed of 100% of calcite (instead of 99%). Two calculations were performed, one with a calcium sulphoaluminate clinker to gypsum ratio of 5.26 and one with a ratio of 2.50.

Effect of limestone filler as mineral addition in self

Limestone filler is regularly used as mineral addition in self-compacting concrete (SCC). Besides the normal cement content (around 300 kg per m³ of concrete), limestone filler is added in quantities of 200 to 300 kg per m³ of concrete. Because of the fundamentally new concept of SCC, the structure of the material, as a result of the hydration process, can show some
