International Conference and Exhibition on Application of Efficient and Renewable Energy Technologies in Low Cost Buildings and Construction, Ankara, Türkiye, 16 - 18 Eylül 2013
The use of inadequate materials in restoration of historical buildings leads to loses in historical
properties of construction. Consequently, the materials used in restoration of historical constructions
have to be similar with the original materials. Khorosan mortar widely used in ancient times is
lightweight material that has adequate strength and workability. In this study, the various type and
ratio of polypropylene fibers, tile powder, slaked lime and water were mixed to prepare Khorasan
mortars, and physical and mechanical properties of specimens were investigated. The unit weight,
ultrasonic pulse velocity, flexural and compressive strength of specimens was determined. Due to
experimental results, the use of polypropylene fibers at high ratio in Khorasan mortar led to increase
in flexural strength and decrease in compressive strength. The increase in polypropylene fiber length
led to increase in flexural strength and decrease in compressive strength. The ratio of tile powder/lime
was determined as 4, and adequate experimental results were obtained by 0-1 mm tile powder. To
obtain adequate strength, polypropylene fiber at the ratio of 3% and length of 12 mm was found
appropriate.
