Modern thermal power plants are producing large amounts of fly ash that is generally quite suitable for use as a supplementary cementitious material in concrete. However, for tilis purpose the fly ash utilization in the United States continues to remain low, mainly on account of lack of quality cont
The hydration of portland cement in presence of citric acid has been investigated. The results indicate that O.l% citric acid accelerates whereas too high a dose (> 0.1%) of citric acid retards the hydration. Electrical conductivity measurements of the paste indicate that in the presence of citric a
White Portland cement, (a cement containing less than 0.3% iron oxide), reacts rapidly with salicylaldehyde (2-hydroxybenzaldehyde), causing rapid setting and hardening in the absence of added water. One of the reaction products was identified as a calcium complex of salicylaldehyde (CHOC6HsO)zCa. T
