Abstract: The long‐term compressive strength of silica‐fume concrete has been recently questioned by some researchers. This paper reports the results of compressive strength data on 4‐ to 6‐year‐old cores obtained from well‐documented ...

Abstract: The abrasion resistance of 12 concretes is compared with the ASTM C779‐82 (procedure C) testing method. Four different types of aggregates were used; their source rocks are completely characterized in terms of compressive ...

Abstract: High- and very high-strength concretes (HSC and VHSC) are often used for building columns. However, closely spaced hoops are necessary to improve the ductility of such relatively brittle concrete. Such a measure of providing ...
