Porosity estimation of cement-lime mortar through the volume calculation method
The presence of lime in mixed mortars is responsible for the increase in the demand for mixing water for a given consistency. The additional water, which is not consumed in the cement hydration, remains free in the system and when evaporating it leads to high porosity in the hardened mortar. This pa...

A presença de cal nas argamassas mistas é responsável pelo aumento na demanda de água de amassamento para uma dada consistência. A água adicional, que não é consumida na hidratação do cimento, permanece livre no sistema e, ao evaporar, dá origem a porosidade elevada da argamassa endurecida. Este trabalho apresenta o método do cálculo de volumes como uma ferramenta para estimar a porosidade de argamassas mistas a partir de seus constituintes, inclusive a cal, bem como sua correlação com propriedades relevantes no estado endurecido. O método apresentado mostrou-se favorável para a previsão de propriedades que definem o comportamento dos revestimentos de argamassa. Os dados apresentados sugerem continuidade e aprofundamento desta linha de estudo envolvendo aspectos não considerados no cálculo teórico de volume, tais como a influência da retração e da carbonatação nas argamassas.

The presence of lime in mixed mortars is responsible for the increase in the demand for mixing water for a given consistency. The additional water, which is not consumed in the cement hydration, remains free in the system and when evaporating it leads to high porosity in the hardened mortar. This paper presents the method of volume calculation as a tool for estimating the porosity of mixed mortars through their constituents, including lime, as well as its correlation with relevant properties in the hardened state. The method presented proved to be adequate for predicting the properties that define the behavior of the rendering.
