KAOLİN ESASLI TEK BİLEŞENLİ JEOPOLİMERLERİN İNCELENMESİ

Bu çalışmada tek bileşenli (beraber öğütülerek bekletilen aluminosilikat ve alkali karışımına su eklenerek üretilen) kaolin bazlı jeopolimerler üretilmiştir. Silis dumanı eklenmesinin ve ön bekleme süresinin jeopolimerlerin mikroyapısına, mekanik ve mineralojik özelliklerine etkileri X-ışını kırınımölçeri (XRD), X-ışını Floresans (XRF), Taramalı Elektron Mikroskobu (SEM), Fourier Dönüşümlü Kızılötesi Spektrometre (FT-IR) kullanılarak incelenmiştir. Tek bileşenli kaolin bazlı jeopolimerlerden 66,73 MPa 7 günlük basınç dayanımı elde edilirken silis dumanı eklenmesi ile dayanım artarak 88,57 MPa ulaşmıştır.

INVESTIGATION OF KAOLIN BASED ONE PART GEOPOLYMERS

Kaolin based one-part geopolymers (produced by adding water to preground aluminosilicate+alkali mixture) were produced in this study. Effect of and silica fume addition and prewaiting time on microstructure, mechanical and mineralogical properties of geopolymers evaluated with X–ray Fluorescence (XRF), X–ray diffractometer (XRD), Scanning Electron Microscopy (SEM), Fourier Transform Infrared Spectrometer (FT–IR). Kaolin based one-part geopolymers gained 7-day compressive strength of 66.73 MPa while silica fume addition enhanced the strength up to 88.57 MPa.
