Experiments Has been made on lime mortar which have a weak
resistance so we added materials like pozolan, and bricks to
improve the mechanical properties of the mixture, as we added
fiberglass to the mix, and study their effect on the mechanical
properties of mortar, also experiments has been made on natural
limestone which used in the construction, experiments on samples
of mural prismatic composed of stone and mortar to see pressure
strength of mural samples, and mural samples subjected to
curvature to determine tensile strength of stone walls with
limestone mortar reinforced with fiber glass.
We observed increase in the mural samples tensile strength about
73% when we added a small amount of fiber glass doesn't exceed
2% of the proportion of the existing lime in the mixture, which
shows the effective improvement in the mortar extracted
specifications.
Restoration of ancient structures is an important part of
reconstruction process which will be witnessed by our country, the
aim of this research is to improve a local manufacturers lime mortar.
This research study the impact of additions to improve
limestone mortar properties to become comparable to hydraulic
lime which is used in other countries, by using additions relative
to that were used in the old mortar, also used modern additions
like fiber glass to limit unwanted contraction in the use of
limestone mortar, , especially in arid environments.
