Method of evaluating silica fume, method of producing concrete composition, concrete composition and hardened concrete |
| abstract |
PROBLEM TO BE SOLVED: To evaluate a concrete composition, a hardened concrete body, and a silica fume which can form a hardened concrete body having good fluidity and high strength using a concrete composition having a water / binder ratio of 0.2 or less Methods and methods of making concrete compositions are provided. SOLUTION: 1 g of silica fume is dispersed in 100 g of water, and the obtained silica fume dispersion is used as a measurement object to measure a particle size distribution. Furthermore, the ultrasonic dispersion liquid which applied the ultrasonic wave of the frequency chosen from 15 kHz-50 kHz to the obtained silica fume dispersion liquid for 540 seconds is made into a measuring object, and particle size distribution is measured. 【Selection chart】 None |
