The mutual interaction of tricalcium silicate (CRS) and B-dicalcium silicate (B-CpS) in their combined h~dration was studied. The rate of B-CpS hydration was accelerated significantly in the presenc~ of CRS. The rate of CRS hydration was retarded, but only i~ the presence of~large amounts of B-C2S.

Beta-dicalcium silicates are synthesized between 1050 and 1550°C and are characterized with respect to their structure defects by cathodoluminescence, thermoluminescence and E.S.R.. Paste hydration kinetics are followed, in the early stage, by electrical conductivity and microcalorimetry ; for longe
Boron, vanadium, phosphorus, arsenic and chromium, well-known for their stabilizing action on beta-dicalcium silicate, are introduced at 0.5 or 3 at-g per cent in the synthesis raw mix. During the early hydration stage, paste electrical conductance and conduction microcalorimetry resuits show how st
