Additives for Grinding Process Concrete ReadyMix Concrete Admixtures It was found that portlandlimestone cement (with 15% limestone) achieves equivalent concrete strength and durability to Ordinary Portland Cement Mechanical Strength The mechanical strength of portland cement (PC) cannot be compared with portlandlimestone cement without a discussion05/02/2021· Reduced cost of cement production through reduced unit grinding costs and through replacement of clinker with reactive additions such as pozzolans, blast furnace slag and fly ash or with fillers such as limestone OPTEVA® CBA® additives are most effective in enhancing compressive strengths of blended cements using up to 40% limestone fillerOPTEVA® CBA® Cement Additive GCPAT
In our labs, we have been able to develop a new chemical for Cement Additives that not only enhances the grinding and performance efficiency of cements but also increases its compressive strength Here’s why our grinding aids are of paramount quality in the industry It improves the compressive strength of cement tremendously Increases the fly ash addition by 24%;particularly in the grinding of Portland and limestone cements Production increases generally vary between 10% and 30%, depending on the fineness of the cement, on the grinding system available, on the clinker mineralogical composition, on the additive dosage etc Specific formulations are available for limestone cement and allow the increase of ultimate strengths;MApei Grinding Aid /C Pack set inhibitors for cement
