Abstract

The aim of this study is to examine the effects of Na-CMC on cement as an alternative chemical admixture in the production of cement with metakaolin by using standard cement experiments. The blended cement mortar which was produced by the use of these Na-CMC was affected changes in the physical (specific gravity, fineness, specific surface area, compressive strength) and the chemical (water demand, setting time, soundness) characteristics. The results of the experiments showed that the Na-CMC, can be used in the atio of up to 20% as a blend setting retarder in cements.

Na-CMC POLİELEKTROLİT İLAVESİNİN PUZOLANLI ÇİMENTO ÖZELLİKLERİNE ETKİSİ

Abstract

Bu çalışmada; çimento üretiminde alternatif kimyasal katkı kaynağı olabilecek Na- CMC’nin çimento özelliklerine etkisi standart çimento deneyleri ile incelenmiştir. Na-CMC katkılı çimento harçlarının, fiziksel (özgül ağırlık, incelik, özgül yüzey, dayanım) ve kimyasal (su ihtiyacı, priz süresi, hacim genleşmesi) özellikleri kimyasal katkıdan etkilenmiştir. Deney sonuçlarından, % 20 puzolanik katkı oranına kadar Na-CMC çimentolarda priz geciktirici katkı olarak kullanılabileceği tespit edilmiştir.
