Abstract

The main target of this study is to explore alternative recycled sand materials to the natural sand. For this, the possible utilization of different types of recycled sand in fly ash-based geopolymer mortar production was experimentally investigated in this study. Within this context, five different types of recycled sand materials acquired from the recycling of construction materials such as concrete, basalt tile, granite tile, marble tile, and ceramics tile were considered to be alternatives to the natural sand. In producing fly ash-based geopolymer mortars, the natural sand was substituted with these recycled sands at five replacement levels of 10, 20, 30, 40, and 50% by volume. Thereby, 26 different geopolymer mixtures, one of which was the control mixture, were designed and manufactured. Unit weight, water absorption, splitting tensile strength, and especially thermal conductivity characteristics of the geopolymer mortars were tested. The results of the experiment showed that the recycled sands did not affect the properties of geopolymer mortars seriously, and it was concluded that they could be used in the production of geopolymer mortars in a controlled manner.

YAPI MALZEMELERİNİN GEOPOLİMER HARÇ ÜRETİMİNDE KUM OLARAK GERİ DÖNÜŞTÜRÜLMESİNİN İNCELENMESİ

Abstract

Bu çalışmanın temel amacı, doğal kuma alternatif olarak geri dönüştürülmüş kum malzemelerinin araştırılmasıdır. Bunun için bu çalışmada, uçucu kül bazlı geopolimer harç üretiminde yapı malzemelerinden geri dönüştürülmüş farklı kumların olası kullanım etkileri deneysel olarak araştırılmıştır. Bu kapsamda, beton, bazalt karo, granit karo, mermer karo ve seramik karo gibi inşaat malzemelerinin geri dönüşümünden elde edilen beş farklı türde geri dönüştürülmüş kum malzemesi doğal kuma alternatif olarak değerlendirilmiştir. Uçucu kül bazlı geopolimer harçların üretiminde, doğal kum, bu geri dönüştürülmüş kumlarla hacimce 10, 20, 30, 40 ve %50’lik oranlarda ikame edildi. Böylece biri kontrol karışımı olmak üzere toplam 26 farklı geopolimer karışımı tasarlanmış ve üretilmiştir. Üretilen geopolimer harçların birim ağırlık, su emme, yarmada çekme ve özellikle termal iletkenlik özellikleri test edildi. Deney sonuçları geri dönüşüm kumlarının geopolimer harçların özelliklerini ciddi mertebelerde etkilemediğini göstermiş olup bu geri dönüştürülmüş kumların kontrollü bir şekilde geopolimer harçların üretiminde kullanılabileceği sonucuna varılmıştır.
