Mechanical Fracture Parameters of Mortars Modified by Burnt Clays

Article Preview

Abstract:

This paper presents the results of three-point bending fracture tests. Specimens were made from lime mortar modified by brick powder or metakaolin. The first, reference mixture only used hydrated lime, while the other mixtures were enhanced by brick powder or metakaolin in amounts of 25, 50 and 100 % of the weight of hydrated lime.
