Mechanical Properties of Mass Concrete at Early Ages

Abstract

A series of early-time material properties tests was conducted on mass concrete mixtures to be used in the construction of locks and dams along the Red River Waterway. Tests were conducted to determine creep, compressive strength, and Young's modulus of elasticity at ages of loading from 18 hr through several days. While a significant data base exists for the material properties of mass concrete at later ages, very few data exist for the early- time material properties of mass concrete. Therefore, this investigation provided a significant contribution to the existing data base. Two common simple models used to predict the strength and Young's modulus of elasticity as functions of time were selected for comparison with early-age mechanical properties test data. The data obtained from the early-time material properties tests were used to evaluate three viscoelastic creep models. The results of the investigation and the analysis are reported.
