Descriptions
The present study aims to apply decomposed granite soil to concrete as fine aggregate. The western region of Japan supplies a large amount of granite soil. This soil has finer particles than sea sand, which decreases slump of concrete. Difference of strength between concretes mixed with sea sand and granite soil is small, if concrete has the same water cement ratio. To increase slump of concrete mixed with granite soil, finer particles than 0.15mm in size were removed from the soil by washing. This washed granite soil improved properties of fresh concrete.
