EFFECT OF CEMENT CONTENT ON SALT SCALING RESISTANCE OF CONCRETE

Two series of air entrained concrete mixes were made to determine minimum cement content necessary for adequate resistance of 20 MPa concrete to salt scaling. Series A consisted of 6 mixes varying in cement content from 240 to 328 kg/cu M. The slumps and air contents were practically constant. Series B consisted of 3 mixes varying in water cement ratio (0.40, 0.45, 0.50). The cement and air contents were practically constant. The salt scaling resistance test was carried out in accordance with A.S.T.M. C672-76 with the exception that the scaling was evaluated by determining the dry mass of the scaled material per unit area instead of by the visual rating. It was concluded that the currently specified (M.T.C. Form 1350) minimum cement content of 310 kg/cu M is essential for adequate resistance to salt scaling. (Author)
