THE MICRO STRUCTURE AND MECHANICAL PROPERTIES OF MORTARS MADE FROM MAGNESIA-PHOSPHATE CEMENT

Mortars made from magnesia-phosphate cement at a water:solids ratio of 1:16 were of high early strength and low porosity. The hydration products were crystalline, often with striking morphology. An increase in the w:s ratio increased the porosity and decreased the compressive strength of the mortars. It also affected the morphology of the struvite crystals, as did the incorporation of sodium tripolyphosphate. At the lower w:s ratio struvite was observed by SEM in the form of needles, while schertelite had a platey morphology. The dramatic crystallinity of these hydrates suggests a through-solution mechanism for their formation. (Author/TRRL)
