Influence of curing conditions in air lime-metakaolin blended mortars – A mineralogical and mechanical study
The need to formulate mortar compositions with adequate durability and compatibility is nowadays one of the major challenges in historical buildings repair. The incorporation of pozzolanic materials as addition or replacement of lime is viewed as a solution to these challenges regarding the increase in hardening time, mechanical strength, water resistance and durability. This paper includes par...
متن کاملAn assessment of lime mortars for masonry repair
Most historic and traditional mortars were made with lime. Due to their nature and function lime mortars weather and need to be replaced. Ordinary portland cement mortars can often be incompatible with historic masonry causing structural and aesthetic damage. Petrographic analysis of original mortars from Clonmacnoise Monastery and Ardamullivan Castle evidenced that they were fabricated with fe...
متن کاملQuantifying the benefits of lime additions in cement based mortars
The European Lime Association (EuLA) have instigated a project to identify and quantify the benefits associated with the addition of hydrated lime to cement based mortars, and more importantly, filling the gaps that exist in the evidence in respect of the benefits of hydrated lime additions to workability, bond strength development, durability and in addition the modes of failure of mortars whn...
متن کاملStudy of Metakaolin-Based Geopolymer with Addition of Polymer Admixtures
In the present work, metakaolin-based geopolymer including different polymer admixtures was studied. Different types of commercial polymer admixtures VINNAPAS® and polyethylene glycol of different relative molecular weight were used as polymer admixtures. The main objective of this work is to investigate the influence of different types of admixtures on the properties of metakaolin-based geopol...
متن کاملBehaviour of a starch as a viscosity modifier for aerial lime-based mortars
Different dosages of a commercialized potato starch were added to aerial lime-based mortars in order to check its efficiency as a rheological modifier. Several fresh state properties of the mortars were studied: consistency, density, air content, water retention capacity, setting time and evolution when applied on support. The effect of the starch on -potential of the lime particle surface as ...
