摘要
PROBLEM TO BE SOLVED: To enhance the durability of a preferable structure of concrete made lightweight by using a lightweight aggregate in relation to high strength lightweight concrete excellent in freeze-thaw resistance; to reduce the total cost and to secure favorable construction in relation to a process for producing the concrete; and to provide the process for producing the concrete.;SOLUTION: A coating layer 3a of slurry-like silica fume is formed at least on the peripheral surface of each particle of a coarse aggregate. High strength lightweight concrete excellent in freezing and thawing resistance, which is obtained by blending the coarse aggregate with a fine aggregate 4 and kneading materials such as cement, and mixing/forming them, is provided.;COPYRIGHT: (C)2004,JPO
