Homework Statement
If limestone (calcium carbonate) and clay (assume aluminum silicate) are mixed together and heated then the result is cement. Cement is a mixture of calcium oxide, carbon dioxide, aluminum oxide, and calcium silicate. These bags can be purchased at any building supplies store. Write the balanced equation for this reaction.
Homework Equations
CaCO3 + Al2(SiO3)3 --> ...? Do I just do a double displacement, or does cement = CaO + Al2O3 + Ca2SiO4?
