Abstract

The effect of aggregate composition on physical and mechanical characteristics of repair mortars P. ~ a n i t a ' & T. C. ~riantafillou~ Laboratovy of Building Materials, Department of Civil Engineering, Democritus University of Thrace, Greece Labovatoiy of Mechanics of Matevials, Depavtment of Civil Engineering, University of Patras, Greece Abstract Mortar is an important material in old masonries. Its repair is leading to the conservation of buildings and structures of our cultural heritage. Old mortars are mainly made of pozzolan, sand, brick powder, lime and water. Repair mortars are made of the same materials whereas cement is often added in small quantities in order to improve the strength development. This paper presents preliminary results of a systematic experimental study on the effect of aggregate type and ratio on physical and mechanical characteristics of repair mortars. Four mortar mixtures were prepared with different pozzolan/brick powdertsand ratios. Compressive strength, fle
