| Abstract: | Aiming at construction condition and performance requirement of drilling shaft lining in special deep alluvium, the preparation principle and preparation approach of high strength and high performance concrete of drilling shaft lining are brought forward. On the base of a great deal test, the raw and processed materials are chose and preparation tests of C60-C70 high strength and high performance concrete of drilling shaft lining are done. The optimizing mixing ratios are gained and have been successfully applied in engineering practice. |
