The chemical analysis of pozzolan-lime pastes at different stages of pozzolanic reaction shows that cohesion is due to the presence of hydrated calcium silicates which have a low basic content and high water content. Aluminates play only a secondary role. The fineness of the pozzolan seems to be the main factor in the increase in the mechanical strength of such pastes. The lime, apart from its role of reagent, could be responsible for an increase in cohesion when it contains clinkerized ingredients. (TRRL)
