RE:Anonymous again the killerWe are talking about how CVX plans to put CO2 into their cement I also brought up the silicon powder that some cement companies use in their cement mix Now I should have also brought up the silicon fume that cellular cement companies use I don't know if CVX has this I their mix but I wonder silicon fume instead of CO2 Whats the Cons and pros of using silicon fume ? And I am sure with few alterations and sinking a few times I will have my dingy floating on the water lol
