Estimation of Evolution of Relative Humidity Distribution for Concrete Slabs
Realistic prediction of concrete shrinkage and creep requires the calculation of the distributions of relative humidity at various times. Although the distributions of the relative humidity can be computed by numerical methods from the differential equation for diffusion, simple prediction formulas can facilitate structural analysis. The purpose of this paper is to present a simple formula for ...

متن کاملInvestigating the Creep Properties of PET-Modified Asphalt Concrete
This study has investigated the creep properties of asphaltic concrete modified with different dosages of waste polyethylene terephthalate (PET) in two different ranges of size. Uniaxial dynamic creep test at 40°C was conducted on the cylindrical specimens of the mixtures. The load was applied in two different frequencies of 0.5 and 5Hz. Creep test results showed that the accumulated strain und...

متن کاملProduction of High Performance Concrete Using Admixtures
In this study, it is aimed that production of high performance concrete using admixtures. The admixture is used to resist against to freezing of concrete, and concrete (C20) is produced, and cured in water. 8 samples are tested in pressure, and mean stress is determined as 28 MPa. Remaining two samples are tested with image processing technique, and determined that sample which containing an ad...
