- Abstract
- Used domestic aggregate for concrete pavement, the mechanical properties of the concrete were investigated and quantitative analyses for the characteristics of the experimental factors were evaluated. This paper reports the results of curing temperature and age on the strength and elastic modulus and it suggests a prediction model based on these experimental results. Tests of 80 specimens made of granite as a coarse aggregate, cured in isothermal conditions of 0, 23, and 45 degrees C and tested at the ages of 1, 7, and 28 days are reported. Based on the experimental result, the relationships between compressive strength and elastic modulus were analyzed, considering the effects of curing temperature and age. Also the relationship between static modulus of elasticity and dynamic modulus of elasticity was investigated and an empirical equation was proposed. The measurements of dynamic modulus of elasticity are usually very convenient, since they are nondestructive and there are few errors among the specimens.
