Assessment of cement characteristics affecting rheological ...

 · The most effective cement characteristics causing incompatibility, hence detraction of paste rheological properties, in decreasing order, were determined as cement fineness, C3S, C3A and equivalent alkali contents. C4AF and C2S contents of the cement were found to have less effect on the cement–admixture incompatibility.

Explained: Cement vs. concrete — their differences, and ...

 · Cement production begins with limestone, a sedimentary rock. Once quarried, it is mixed with a silica source, such as industrial byproducts slag or fly ash, and gets fired in a kiln at 2,700 degrees Fahrenheit. What comes out of the kiln is called clinker. Cement plants grind clinker down to an extremely fine powder and mix in a few additives.
