Bu çalýþmada öncelikle Bien Seramik Fabrikasýndan temin edilen kusurlu karo atýklarý öðütülerek 212 μm elekten elenmiþtir. Elde edilen karo atýk tozlarý, kýrma kum ve 10M, 12M, 14M’lýk deriþimlerde NaOH çözeltisi ile harç numuneleri hazýrlanmýþtýr. Elde edile harç numuneleri taze haldeyken prizini almasý için 90°C’de 24 saat süreyle etüv ortamýnda bekletilerek geopolimer harç numuneleri üretilmiþtir. Numuneler 3, 7 ve 28 günlük hava kürüne tabi tutulmuþtur. Geopolimer harç numunelerine birim aðýrlýk, yoðunluk, su emme, görünür porozite, ulrases geçiþ hýzý ve basýnç mukavemeti deneyleri uygulanmýþtýr. Deneyler sonucunda, su emme deðerleri, görünür porozite deðerlerinin NaOH deriþiminin artmasýyla azaldýðý, birim aðýrlýk, ultrases ve basýnç mukavemeti deðerlerinin arttýðý, yoðunluðun ise belirgin bir deðiþikliðe uðramadýðý tespit edilmiþtir.

In this study, first of all, defective tile wastes obtained from Bien Ceramic Factory were ground and sieved through a 212 μm sieve. Mortar samples were prepared with the obtained tile waste powders, crushed sand and NaOH solution at concentrations of 10M, 12M, 14M. Geopolymer mortar samples were produced by keeping the obtained mortar samples in an oven environment at 90°C for 24 hours in order to set them while fresh. The samples were subjected to air curing for 3, 7 and 28 days. Unit weight, density, water absorption, apparent porosity, ultrasound penetration rate and compressive strength tests were applied to the geopolymer mortar samples. As a result of the experiments, it was determined that the water absorption values and the apparent porosity values decreased with the increase in the NaOH concentration, the unit weight, ultrasound and pressure strength values increased, and the density did not undergo a significant change
