A Fundamental Study on the Influence of Types of Aggregate on the Engineering Properties of EPSB Concrete

EPSB 콘크리트의 공학적 특성에 미치는 골재 종류의 영향에 대한 기초적 연구

The use of lightweight concrete products is usually increased at a recently high structures. Among the rest EPSB concrete products which have an excellence on the sound and thermal insolation are used. Also, the gathering of nature aggregate is limited, so that lack of fine aggregate is appearing. The purpose of this study is to obtain basic data of properties of EPSB concrete in according to types of aggregate. The results of experiment are as follow. The EPSB concrete using bottom ash is appeared the lowest slump in fresh concrete. The EPSB concrete using river sand and bottom ash are showed as a similar compressive strength except it using crushed sand in hardened concrete.
