Abstract: An experimental investigation was carried out to determine the suitability of fiber‐reinforced cementitious composites containing high‐volume fractions of very fine (micro) fibers of carbon and steel for thin repairs. Two ...

Abstract: When concrete is sprayed during shotcreting, inevitably some material is lost due to rebound. The relative losses for coarse aggregates and fibers are higher than that for the rest, and therefore the composition of the ...

Abstract: With the attractive possibility of offshore concrete casting in mind, the effects of marine curing on the pull‐out behavior of steel fibers were investigated. Single fiber pull‐out specimens were chosen to clearly examine ...

Abstract: Coefficients of permeability are obtained for cylindrical paste specimens frozen at the ages of 4, 24, 48, and 72 hours after casting. Two freezing temperatures of

Abstract: This study investigated the effect of CaCl2-blended acrylic polymer emulsion (CP) at 0%, 0.5%, 1.0%, and 1.5% by weight of cement on the degradation of alkali–silica reaction (ASR) susceptible fine aggregate particles. ...

Abstract: The paper describes an experimental program in which four deformed commercial fibers with widely different geometries were investigated in steel‐fiber reinforced concrete. Three matrices with compressive strengths of 42, ...

Abstract: As part of a larger investigation in steel‐fiber‐reinforced wet‐mix shotcrete, companion specimens were cast using the shotcrete mixes for a direct comparison with shotcrete after hardening. Deformed steel fibers with five ...

Abstract: Water‐permeability measurements were made on 50 mm diameter and 100 mm long cored cylinders obtained from a roller compacted concrete pavement that was 160 mm in average thickness. A triaxial permeability cell was used. ...
