dc.description.abstract | Maturity method is a non-destructive method for estimating in-place concrete strength as a function of time and temperature. The main objective is to use maturity method determining joint sawing and traffic opening time for whitetopping construction in Korea. Another objective is to investigate the influence of air temperature in the correspondence to slab temperature and maturity value. For determining the joint sawing and traffic opening time, thermachron i-button and strain gage were inserted in the fresh concrete in the slab and a maturity value was calculated at desired times. In-place strength was then estimated from a pre-established relationship between maturity values and compressive strength. The results showed that there are significant differences between the estimated strength obtained from maturity curve and in-place concrete strength. The reasons are that the gain of in-place concrete strength was influenced by several factors in the field such as curing conditions, air temperature, and wind speed etc. Also, the results showed that air temperature had significant influence on slab temperature and maturity value. The slopes of maturity curves exponentially decrease as air temperature decreases. This means that maturity value sharply dropped as air temperature decreases. | - |
