The suppression effect of high performance cement on ACR expansion was tested with the concrete microbar method raised by the former Nanjing University of Chemical Engineering [7].
As the cement was excellent in decreasing charge passed and defending NaCl and MgSO4 aggression, the product was also quite suitable for oceanic and offshore engineering.

Predicting the Ultimate Bearing Capacity of Single Piles based on CPTU Miao Yong-hong1,2,a，Cai Guo-jun2,b, Liu Song-Yu2,c 1 Department of Civil Engineering ,Jiangsu University, Zhenjiang , China 2 Institute of Geotechnical Engineering, Southeast University, Nanjing，China ayhmiao1998@163.com, bfocuscail@163.com, cliusyl@seu.edu.cn Key words：cone penetration test (CPT);piezocone penetration test（CPTU）; bearing capacity; pile; static loading test Abstract：Six methods to determine axial pile capacity directly based on piezocone penetration test (CPTU) data are presented and evaluated.
Results of the analyses showed that the best methods for determining pile capacity are the CPTU methods. 1 Introduction Determination of the ultimate capacity of piles is necessary for the safe geotechnical engineering design.
The accurate prediction of pile capacity is always a challenge to design engineers, which can be achieved using different methods.
The authors consider the indirect methods less suitable for use in engineering practice and will not refer them further.
