I'm quite interested at this question, since there wouldn't be any chemical reaction between limestone surface and cement based on my limited stone knowledge.However, one paper:Cement and Concrete Research 30(2000):683-691, gave out an example in the introduction to say, limestone aggregate can react chemically with the cement components to form "carboaluminates" or "calcium carbonate-calcium hydroxide" complexes. I can't find any clear evidence to support this. Do you have any idea or evidence to say chemical reaction between them?

Thanks.
