SLAG CEMENT--FOR USE AS A PARTIAL REPLACEMENT OF TYPE 10 PORTLAND CEMENT IN CONCRETE

Field and laboratory tests were carried out to determine the effect of slag cement in 20 and 20 MPa air entrained concrete on the salt scaling resistance and compressive strength. The slag cement to total cement ratio varied from 0 to 0.325. The field tests involved curb and gutter on Highway #3, near Port Colborne. Standard salt scaling slabs and cylinders were made at the job site for testing in the laboratory. No sign of salt scaling was evident in the curb and gutter, after exposure to two winters. All of the scaling slabs showed good resistance to the laboratory salt scaling exposure (A.S.T.M. C 672-76). There was an indication that the concrete with the slag cement developed strength at a lower rate at early ages than the concrete with no slag cement. The use of 25 percent replacement of Type 10 Portland Cement with the slag cement is recommended for a limited number of contracts. Final approval of the slag cement to be based on at least two years performance on the test contracts. (Author)
