Abstract

In this study, grinded Bayburt Stone has pozzolanic property with 45 µm and 125 µm fineness was replaced with PC 42.5R (CEM-I) type cement at ratio of 0%, 10%, 20%, and 30% by weight. The aim of this study was made up in two phase, one of them was to investigate the effects of Bayburt Stone waste contain zeolite with different fineness on physical and mechanical properties of composite cements and the other one was to investigate behavior of same superplasticizer belong to two different company. Standard consistency, setting time and volume expansion tests are performed on the cement pastes and compression strength and flow tests are performed on the cement mortars. Mortar specimens are kept in standard curing for 28 days, than compressive strength test are performed at the ages of 2, 7 and 28 days. As a result, changes in specific surface area depending on the particle size distribution of mineral additives makes significant different on the physical, mechanical and rheological properties of cement mortars. In this study, it was determined that same type of superplasticizers which had different companies could be used in blended cement replaced with Bayburt stone.

Özet

Bu çalışmada, puzolanik özelliğe sahip 45 µm ve 125 µm incelikte öğütülmüş Bayburt taşı PÇ 42.5R (CEM I) çimentoda sırasıyla ağırlıkça %0, 10, 20 ve %30 ikame edilmiştir. Çalışmanın amacı iki aşamada oluşturuldu: birincisi farklı inceliklere sahip zeolit içeren Bayburt taşı atıklarının CEM I tip çimentoya ikame edildikten sonra elde edilen çimentonun basınç dayanımı ve fiziksel özelliklerine etkilerini değerlendirmek, diğeri üretilen çimentoların farklı firmalara ait aynı tip süperakışkanlaştırıcılarla davranışını incelemektir. Hazırlanan hamur numuneler üzerinde standart kıvam, priz süreleri ve hacim sabitliği gibi standart çimento deneyleri, harç numuneler üzerinde yayılma ve basınç dayanımı deneyleri gerçekleştirilmiştir. Harç numuneler 28 gün standart küre bırakılmış ve ardından 2, 7 ve 28 gün yaşlarında basınç dayanımı deneyi yapılmıştır. Sonuç olarak özgül yüzeye bağlı olarak değişen incelik fiziksel, mekanik ve reolojik özellikleri önemli derecede etkilemiştir. Bu çalışmada farklı firmalara ait polinaftalin sülfonat tipi süperakışkanlaştırıcıların beyaz Bayburt taşı ikameli çimentolarda kullanılabileceği belirlenmiştir.
