| Research on correlation between inspected wave speed and strength in foundation pile using high-performance concrete |
| 摘要 |
| 用基樁采用的高性能混凝土配合比制作試件，開展波速與強(qiáng)度關(guān)系的試驗(yàn)研究。試驗(yàn)結(jié)果表明：高性能混凝土強(qiáng)度與波速隨齡期增長而增長，其中早期波速增長迅速，28 d以后波速基本穩(wěn)定；強(qiáng)度隨齡期增長較為緩慢，28 d以后仍繼續(xù)增長。根據(jù)波速與強(qiáng)度關(guān)系及波速試驗(yàn)結(jié)果，給出了C25 |
