The present study work was carried out to determine the effect of Non Chlorides Hardening Accelerators with different cementations’ materials i.e. OPC & PPC. On concrete mixtures when Non-Chlorides Accelerators used in OPC mixtures with water curing, keeping the ascending dose of non chlorides hardening accelerators i.e. 0%, 0.58%, 0.73%, 0.87%.The two strength properties of concrete determined in experimental work namely compressive strength and flexural strength at 7 and 28 days. The effect of accelerators enhancing the flexural strength was found to be fading at later age of concrete which was also observed in case of compressive strength. The maximum percentage gains at 7 and 28 days were 27.18 & 20.48 respectively recorded at maximum dosage of accelerators. In case of PPC mixtures, Non chlorides hardening accelerators rage kept – 0%, 0.57%, 0.72%, and 0.85%. In PPC mixtures also moderate to high increase in the flexural and compressive strength was observed at early age with increasing the dosage of accelerators Hence through the result conclusion high early strength concrete mixtures can be obtained by using Non chlorides hardened accelerators and two types of cementations materials i.e. OPC & PPC. With different curing methods namely water curing and curing with membrane forming curing compounds.
