Abstract Byusing the simplex centroid design method, the cementitious system of cement-limestone powder-slag cement pastes was designed, and then effects of carboaluminate on the anti-chloride ion penetration performance, Friedel's salt and pore structure of cement pastes were also investigated through X-ray diffraction analysis, thermogravimetric analysis and mercury intrusion porosimetry. The results show that, the chloride migration coefficient of cement pastes with 25% and 50% limestone powder increased by 193.02% and 534.50%, respectively, compared with that of cement pastes without limestone powder; the chloride migration coefficient of cement pastes with 25% limestone powder and 25% slag decreased by 85.98%, compared with that of cement pastes with 50% limestone powder. The amount of carboaluminate increased with the increase of limestone powder. The incorporation of slag increased the content of carboaluminate. The diffraction peaks of carboaluminate were not found after RCM test. The amount of Friedel's salt of cement pastes with 0%, 25% and 50% limestone powder was 2.74%, 2.94%, 1.09%, respectively. Compared with cement pastes with 50% limestone powder, the amount of Friedel's salt of cement pastes with 25% limestone powder and 25% slag increased by 363.30%. The more limestone powder was added, the larger porosity and the most probable pore diameter of the cement pastes were. The porosity and the most probable pore diameter of cement pastes with 25% limestone powder and 25% slag decreased by 31.23% and 57.84%, respectively, compared with that of cement pastes with 50% limestone powder. The formation of Friedel's salt after RCM test improved the pore structure of cement pastes.

Key words： limestone powder slag chloride migration coefficient carboaluminate Friedel's salt
