Decided on white cement with granite chips for the counters. Here's the construction process after building the support walls.
Fill the major portion with normal cement and then cover with the white cement and granite chips (granito). I chose size number 2 for the granite size but larger might have been more interesting. Next comes a lot of sanding with a grinder followed by hand sanding with wet/dry sandpaper.
