The combined effect of sodium lignosulfonate and sodium carbonate on the C4AF hydration was examined by DTG and TG curves and by zeta potential measurements. In the presence of lignosulfonate-carbonate systems the C4AF hydration is completely blocked. The higher the percentage of admixtures, the lon

The combined effect of lignosulfonate and sodium carbonate on the hydration of C3A and C3A-Na20 solid solution was examined by DTGandTG curves, by XRD analysis and by zeta potential measurements. It is confirmed that the simultaneous addition of lignosulfonate and carbonate completely blocks the C3A
In as series of cements made out of clinkers with variable C3A/C4AF ratios and containing different amounts of gypsum, the strength development and the composition of the hydrated material were studied. For a single clinker composition the obtained strength appears to be just a function of porosity.
The influence of Sea, ground, Nile and drinking waters on the microstructure of some hydraulic cements is investigated by means of X-ray diffraction analysis. The calcium sulfo-and carboaluminate hydrates form well with a water cement ratio of 2. Seawater leads to the precipitation of gypsum. The
## Abstract Waterβsoluble melamine formaldehydeβfree polycondensate products were prepared. The chemical structure of these polymers was confirmed with different spectroscopic techniques. The effects of these polymers on the rheological properties of the cement pastes were investigated. The rheolog
