Availability waste remelting of nickel ore in the form of slag is increasing,this is caused by the high nickel production to meet the development needs and to increase the alloying element material for construction materials This research is making a paste of a mixture of slag Nickel Pig Iron (NPI) from PT Indoferro used as a substitute in the manufacture of cement paste. <br /> <br /> The material used in this study are cement, nickel slag, water, zeolite. Cement paste made with dimensions of 10 cm x 5 cm with each slag used as an amplifier on pasta with variations in volume of 15%,30%, 45%, 60%. Material each weighed in accordance with the mix design and then done mixing the material after the homogeneous material to be put into the mold and then on let stand for 24 hours until the paste solidifies and hardens, after 24 hours of sample paste is removed from the mold and then do the treatment at room temperature, after age meets conducted testing on samples of paste. <br /> <br /> The test results showed that the variation additions press slag on pasta mixture that gives the minimum compressive strength is 15% for slag variant NPI. Then the test results showed that the variation additions press slag on pasta mixture that gives the maximum compressive strength is 40% for slag variant NPI. The test result ion chloride coefficient of the slag cement is much lower than that cement.Therefore, it may be concluded that the slag cement showed better resistance to chlorides ion penetration than cement, is 0,96% and 1,39%.
