Influence of Fresh Concrete Properties on the Mechanical Properties of Hardened Concrete

open access: yesInternational Journal for Research in Applied Science and Engineering Technology, 2023
Abstract: Characteristics of hard concrete such as compressive strength are significantly affected by freshly prepared concrete properties. The properties of fresh concrete affect the future performance of structures. Compressive strength is found to be major parameter indicating condition of any concrete structures.
