Investigation on the effectiveness of chemically synthesized nano cement in controlling the physical and mechanical performances of concrete

•Reduction of CO2 emission during cement production utilizing alternative way.•Chemical synthesis of nano cement.•Effectiveness of synthesized nano cement on mechanical performances of concrete.•Effective reduction of curing period for building construction.•Design of a model in controlling the overall performances of nano cement concrete.

Present investigation deals with the effectiveness of the chemically synthesized nano cement in controlling physical and mechanical performances of concrete. In this investigation, concrete samples were fabricated using variable amounts of aggregates and alkali activator content w.r.t. weight of nano cement. Based on the mechanical properties analyses, it is assessed that chemically synthesized cement is able to produce 43 MPa compressive strength of concrete after 14 days curing instead of 28 days at an optimized amount of aggregates content as well as alkali activator content. Finally, a model has been proposed to explain the overall performances of nano cement based concrete.
