Abstract
Grouts are fluid mixtures of binders with water, for the filling and strengthening of masonry or the consolidation and preservation of mortar stratification. In this paper, totally 15 compositions of lime-based grout mixtures containing admixtures and silica nano-particles were designed, manufactured and experimentally tested in order to evaluate their properties in fresh (fluidity, permeability, volume stability) and hardened state (shrinkage deformations, mechanical strength). Conclusive remarks were attained regarding the influence of silica nano-particles in grouts performance.
