Originální abstrakt

This work focuses on comparing the effect of ten different types of pozzolans on thestrength of lime pastes in relation to their pozzolanic activities as determined by the Chapelle testand monitoring the reactivity of these pozzolans using the thermogravimetric method. It was foundthat the Chapelle test can in some cases overestimate the reactivity of the pozzolan due to differencesbetween the conditions during the test and in reality. The strengths of lime-pozzolan pastes did notcorrelate well with the pozzolanic activity values of the pozzolans used. On the contrary, the amountof reacted lime in the pastes, determined by the thermogravimetric method, correlated very well withthe compressive strengths of the pastes.
