Influence of Flax Oil Additive on Rheological Properties of Lime Mortar

Article Preview

Abstract:

Lime based mortars rank to the oldest used building systems used by human civilization worldwide. These materials offer suitable properties for various applications; however its low resistance in moist environment is their significant weakness. Hence, they were modified by number of additives and admixtures. The flax oil was applied to historic mortars to achieve hydrophobization, additionally this additive has considerable influence on the properties of fresh mixture as well. This paper introduces an experimental study dealing with the influence of flax oil on the properties of fresh lime based mortars with various water-to-binder ratios. The results of rheology properties were accompanied by the determination of mechanical performance, basic shrinkage and bulk density of hardened mortars.
