摘要
PROBLEM TO BE SOLVED: To provide a low shrinkage ultra-high strength concrete composition which is free from occurrence of cracks, and a precast concrete product obtained by using the same with self-filling function.;SOLUTION: An inert fine powder having a Blaine value of 3,000 cm2/g is added to cement of ≥500 kg per 1 m3 of concrete, and the total of the specific surface areas of the cement and the inert fine powder is set to be 250,000 to 500,000 m2.;COPYRIGHT: (C)2004,JPO
