Performance of carbonated calcium silicate based cement
May 15 2016 · Villani et al. proposed a schematic of the microstructure for a composite prepared by carbonating a calcium silicate cement (CSC) in wet conditions (or carbonated wollastonite) showing evidence of two different pore sizes (i.e. large pores and small pores).The large pores are derived from the interstitial space between unreacted CSC particles and the small pores are part of the silica gel.

What s the advantages and application of high alumina cement
If you notice closely 3 and 4 has an alumina in there. If in a type of cement the amount of these two especially C 3 A is higher than normal it is called high alumina cement. The amount normally comes to about 8 to 15 . Its major characteristic is quick setting and high early age strength.
