Abstract: It is shown by reference to the literature that salt (NaCl) must be used in the mixture when placing a fluid hydraulic cement mixture in contact with salt. If this is not done a void will be created at the contact of the salt and the cement-based mixture due to solution of salt by mixing water in the mixture. The addition of salt (NaCl) may affect setting time of the cement, viscosity and slurry weight of the mixture, and may cause foaming. It is usually possible to deal with these effects or to overcome their undesirable consequences by use of other admixtures so that they become secondary considerations to the use of salt. Salt (NaCl) will be used in the fluid cement-based mixture anytime salt will be present in the host environment. Trial mixtures must be made and modified as needed to obtain suitable workability.
