Abstract


This article studies the effects produced by the lime filler on the Portugal cement used with additions in the production of mortars.
The starting point is a Portland cement to which different ratios of lime filler, ranging from 0-50%, are added. The next step consists of preparing mortar specimens using standardized sand as aggregate, curing them up to the age of 28 days when they are put to flexo-tensile and compression tests.
The mortar strength is fixed at the age of 28 days, making it coincide with the strength of a pattern cement mortar (cement without additions) of the same age. Then the effects of the filler on the slump and the water cement relation are observed for fixed strength.
