Toughness of fibre reinforced hydraulic lime mortar. Part-1: Quasi-static response

Toughness of fibre reinforced hydraulic lime mortar. Part-1: Quasi-static response There are several stone masonry structures of historical importance in Canada that lie in regions of varying degrees of seismicity. Hydraulic lime mortars are used in the repair of such heritage buildings. While this mortar works as a sacrificial element in the stone masonry system, a tougher and more durable mortar is expected to offer the best repointing binder. This paper reports the results of a study on the compressive, flexural and shear toughness of plain and fibre reinforced hydraulic lime mortar.

Abstract

There are several stone masonry structures of historical importance in Canada that lie in regions of varying degrees of seismicity. Hydraulic lime mortars are used in the repair of such heritage buildings. While this mortar works as a sacrificial element in the stone masonry system, a tougher and more durable mortar is expected to offer the best repointing binder. This paper reports the results of a study on the compressive, flexural and shear toughness of plain and fibre reinforced hydraulic lime mortar. Polypropylene micro-fibres were incorporated at 0, 0.25 and 0.5% volume fraction. As expected, hydraulic lime mortar was seen to be weakest in flexure. However, fibres were effective in increasing the flexural toughness as well as the shear strength.
