Abstract

Polycarboxylic acid type superplasticizers with pozzolanic and inert mineral additives or viscosity modifying chemical admixtures are being used in order to obtain flowability and stability in self compacting concrete (SCC) technology. These admixtures can enhance the fresh state properties of SCC and also improve the strength and durability properties. In this study, surface abrasion resistances of SCCs, produced by using different viscosity modifying mineral admixtures with different aggregate gradings, have been compared with conventionally compacted concretes of the same strength class.

Özet

Kendiliğinden yerleşen beton (KYB) teknolojisinde akışkanlık ve stabilitenin bir arada sağlanabilmesi için yeni nesil polikarboksilat bazlı süperakışkanlaştırıcılar ile birlikte puzolanik ve inert mineral katkılar veya viskozite arttırıcı kimyasal katkılar kullanılabilir. KYB teknolojisinde sıkça kullanılan bu katkılar, KYB'nin işlenebilirliğini önemli ölçüde etkilediği gibi, dayanım ve dayanıklılığında da farklar yaratmaktadır: Yapılan bu çalışmada, aynı çimento dozajında farklı viskozite arttırıcı mineral katkılar ve farklı agrega granülometrileri ile kendiliğinden yerleşen betonlar üretilmiştir. Bu betonların dayanım sınıfına eşdeğer, geleneksel sıkıştırma işlemi görmüş betonların yüzeysel aşınma performansları makalede açıklanan bir yöntem ile karşılaştırmalı olarak incelenmiştir.
