Additional C-S-H can form in both the portland cement-soil and lime-soil systems due to the reaction between Ca(OH)2 supplied by either cement or lime and the silica supplied by soil. This process is known as a pozzolanic reaction. Calcium may also react with alumina and produce C-A-H that is cementitious in nature.
