32 produce a low carbon concrete. JK Lakshmi Cement Limited had developed the new additives in the name of Pozzo Plus + (PP+) (Indian Patent Application No- 201711019131A, Published on 22/03/2019) for cement and concrete.This invention provides a cost-effective green performance enhancing additive for Cement, Concrete, and Mortar. Portland cement-43 grade (OPC) was obtained from JK Lakshmi Cement Limited, Haryana, India. The oxide and mineral compositions of OPC 43 Grade cement 2.1 Mix proportion of Mortar using different concentration of Green Cementing additives. The designs of mortars with OPC cement in the ratio of 1:3 (1 Part Cement and 3 Part Ennore Sand) are given in Table 2. Fixed W/C ratio was used during the cube casting.
