THE CONTACT COMPATIBILITY OF CONCRETES MADE FROM DIFFERENT TYPES OF CEMENT' SUPERSULPHATED CEMENT, PORTLAND CEMENT AND BLAST FURNACE CEMENT /TO BE CONTINUED/

THE AGGRESSIVE NATURE OF SUB-SOIL WATER /SULPHATED, OR POLLUTED BY DIVERSE INDUSTRIAL OR ORGANIC WASTE/, MEANS THAT STRUCTURES OF PORTLAND CEMENT CONCRETE FREQUENTLY REST UPON FOUNDATIONS OR PILES OF SUPERSULPHATED CONCRETE. THIS IMPLIES THE EVENTUAL PRESENCE IN THE YARD OF TOTALLY DIFFERENT TYPES OF CEMENT. SOME ENGINEERS HAVE SEEN IN THIS THE DANGER THAT THE ACCIDENTAL MIXTURE OF TWO DIFFERENT TYPES OF CEMENT COULD PRODUCE GRAVE DIFFICULTIES, SUCH AS THE PHENOMENON OF DISINTEGRATION WITHIN THE CONTACT ZONE OF THE TWO DIFFERENT CONCRETES. THESE OPINIONS ARE PROBABLY BASED ON THE CASE OF POROUS OR BADLY LAID CONCRETE, SINCE AS YET NO GENERAL CONCLUSIONS CAN BE DRAWN FROM EXPERIENCE IN THE USE OF DIFFERENT TYPES OF CONCRETE. IT DOES HOWEVER SEEM OPPORTUNE AND NECESSARY TO EXAMINE THE BEHAVIOUR OF MIXTURES CONTAINING PORTLAND AND SUPERSULPHATED CEMENTS, IN RESPECT OF RESISTANCE, STABILITY UNDER WATER, AND JOINT CONTACT OF THE TWO DIFFERENT TYPES OF CONCRETE. /LCPC/A/RRL/
