Understanding Limestone in Cement Concrete Construction ...

2015-03-26  Here in the U.S. it is long past when finely ground limestone was added to cement to make “adulterated” cement. Although this remains a problem, mainly in the third world where cement is used in bags or sold by unscrupulous middle men, this is not the addition of limestone that is occurring in some markets now.

Role of lime stone in cement? - Page 1 of 2

Bensted and Kantro) have found that while limestone cannot be used as a total replacement for gypsum, it is possible to replace a portion of the gypsum with limestone without significant problems with cement performance. The exact amount of substitution depends on the cement and the fineness of the limestone. They suggest that, due to the mitigating effects of the carboaluminate formed by the ...
