Abstract

Historical buildings are made of
traditional materials such as mud bricks, lime mortars, stone, and wood. Mudbrick is not a durable material against water and compression effects. The aim
of this study is to increase the usage of natural pumice in both mortar and
block production to obtain efficient restoration material in this area. The
specimens obtained by using pumice, slaked lime, tile dust, gypsum and expanded
clay at certain ratios were cured in both steam and laboratory conditions. The
characterization of the raw materials and specimens were carried out by using BET,
XRD, SEM analyses. Also, the physical and mechanical properties of the mortar
and block specimens were determined with laboratory tests. The test results
showed that the highest compressive strength values were obtained from steam
cured specimens. It was observed that the water absorption values ​​of the
specimens which were steam cured slightly better than the naturally cured
specimens.
