This study investigates the interrelations among splitting tensile strength fspt, compressive strength fc’, and Young’s modulus Ec of early age concrete cured under different temperature histories. The concrete of cylindrical specimens were mixed with the same water to cement ratio and with different types of cements, OPC, BB, and LH cements. It was found that fspt-fc’ relationship and Ec-fspt relationship of early age concrete were unique regardless of types of cements and curing temperature histories. Accordingly, new equations of the two relationships were developed and proposed.
