Resistance to Frost Damage at Early Age and Strength Deveropment at Low-Temperature on Concrete Using Various Recycling Materials

Abstract

Toshiji MIMORITakao TAIRAKU Yukio HAMA Osamu SENBU This paper reports the results of the experiment on resistance to frost damage at early age and strength development at low-temperature on concrete using various recycling materials.Results show compressive strength to prevent frost damage at early age can be set at 5N/mm 2 , which is equal with normal concrete in any case. Low-temperature strength development of concrete using high-strength artificial aggregate, electric arc furnace oxidizing slag aggregate and normal eco cement is equal with normal concrete.
