The durability of cement mortar and concrete in sea water has been a subject of serious controversy between cement manufacturers and scientists during the past fifteen years, owing to frequent failures of sea works in which concrete blocks have been used. Dr. Michaelis, one of the highest authorities on the subject, has gone so far as to declare, on the ground of his careful researches, that Portland cement as now manufactured is incapable of resisting indefinitely the action of sea water, and, as an improvement, he has proposed the addition of trass, pozzuolana and siliceous materials of similar nature, capable of taking hold of the calcium hydrate liberated in cement during the progress of induration. A similar view is held by MM. Le Chatelier, Ferret and a host of chemists and engineers.
