INVESTIGATION OF THE PROPERTIES OF HORASAN MORTAR WITH POLYPROPYLENE FIBER ADDITIVE

Abstract

This study was carried out on horasan mortar which is frequently used in historical artifacts. Polypropylene fiber was used as an additive in the production of horasan mortar. The mortar mix is composed of natural hydraulic lime, brick broken, standard sand, polypropylene fiber and water. Two different sizes of brick broken, 0-2mm and 0-4mm, were used in the mixtures. In addition, 0.2%, 0.4%, 0.6%, 0.8% and 1% polypropylene fibers were added to the mortars and the effect of varying additive ratios on the properties of the mortars was investigated. 40mmx40mmx160mm prismatic horasan mortar samples were produced using a mortar mold. On the produced horasan mortars, the spreading test, on the 28 and 90 days prismatic mortar samples, unit volume weight, water absorption, ultrasound transit time, bending strength and compressive strength tests were carried out. According to the data obtained, the highest strength values were achieved by using 0-4mm brick broken and 0.6% polypropylene fiber. It has been determined that 0.8% polypropylene fiber should be used in the case of 0-2mm brick broken in the horasan mortar mixture.
