Proposal of Plane Spacing Factor for Analyzing Air Void System in Concrete
콘크리트 공극 분석을 위한 평면간격계수의 제안

Abstract
Air void systems in hardened concrete has an important influence on concrete durability such as freeze-thaw resistance, water permeability, surface scaling resistance. Linear traverse method and point count method described at ASTM are the routine analysis of the air void system that have been widely used to estimate the spacing factor in hardened concrete. Recently, many concretes often have a spacing factor higher than the generally accepted
