EVALUATION OF CAPPADOCIA PERLITES AS A BUILDING MATERIAL WITH NATURAL STONE RESIDUES

Abstract

The superior properties of perlite (thermal insulation, sound insulation, fire resistance, lightness) haveled to the investigation of the possibilities of perlite usage in many areas. Although perlite haspozzolanic properties and does not have reserve problems in our country, it has not been a preferredmaterial by cement manufacturers. The use of marble travertine residues in cement production is notvery common in our country, although some cement manufacturers support it. In this study, theavailability of cement samples produced by the use of natural perlite and marble travertine residuesbelonging to Nevşehir Acıgöl region in pozzolanic and doped Cements was investigated. In this study,the availability of cement samples produced by the use of natural perlite and marble travertineresidues belonging to Nevşehir Acıgöl region in pozzolanic and doped Cements was investigated.Portland cement 5%, 10%, 15% and 20% marble travertine residues and perlite were replaced bypozzolanic and doped Cements and their properties were tested and their suitability investigated. Inthe experimental studies, 4 types of perlite-doped pozzolanic cement, 4 types of marble travertinedoped cement and composite Cements were produced. In the study, density, cement fineness, settingTimes, water content, volume expansion, compressive strength tests were performed on the producedcements under laboratory conditions. The physical and chemical properties of the blended cementsproduced were compared with Portland cement. When the results of the experiment were examined,the increase in contribution rates decreased the pressure resistances of the concretes. The setting timesof cement mortars increased and also contributed positively to the workability of concrete. There wasno adverse effect on volume expansion. The pozzolanic and doped cements produced with perlite andmarble travertine residues are within the standards according to TS en 197-1 and in cement productionof both materials separately to 20 % and together up to 40% pozzolanic cement production up to 35%Portland Composite cement production can be used.
