Predicting the early strength to determine the curing time required for concrete to reach 5 ~ 10 MPa is an important factor in shortening the construction period and quality control. In this study, to develop a prediction formula for the early strength of two-component concrete, concrete mixed with blast furnace slag was mixed, and the compressive strength at three levels of curing temperature and the maturity were measured using a temperature sensor at the center of the test specimen. As a result, among the Plowman, Logistic, and Gompertz equations, the Gompertz equation was found to be the most suitable for predicting early-age compressive strength.

摘要

Predicting the early strength to determine the curing time required for concrete to reach 5 ~ 10 MPa is an important factor in shortening the construction period and quality control. In this study, to develop a prediction formula for the early strength of two-component concrete, concrete mixed with blast furnace slag was mixed, and the compressive strength at three levels of curing temperature and the maturity were measured using a temperature sensor at the center of the test specimen. As a result, among the Plowman, Logistic, and Gompertz equations, the Gompertz equation was found to be the most suitable for predicting early-age compressive strength.
