Abstract

In this study, lightweight concrete was investigated by using perlite (Pe), pumice (Pu), and waste rubber aggregates (R). The changes in compressive strength of lightweight concrete were investigated, while ultrasonic pulse velocity and density properties were compared after high-temperature exposure (300, 500 ℃). In this context, 11 different types of mixtures were produced. Combinations were formed by keeping the w/c ratio constant. As a result of the experiments, increases in compressive strength were determined at 300 ℃ in general. The compressive strengths of concretes produced using waste rubber aggregates were lower than concretes using pumice and perlite aggregates. It was determined that concrete made using waste rubber exhibited more ductile fracture during compression loading.

Özet

Bu çalışmada perlit (Pe), pomza (Pu) ve atık kauçuk agregaları (R) kullanılarak üretilen hafif betonların performansları incelenmiştir. Hafif betonun basınç dayanımındaki değişimler incelenirken, yüksek sıcaklığa (300, 500 ℃) maruz kaldıktan sonra ultrasonik ses geçiş hızı ve yoğunluk özellikleri karşılaştırılmıştır. Bu kapsamda 11 farklı karışım üretilmiştir. Kombinasyonlar s/ç oranı sabit tutularak oluşturulmuştur. Yapılan deneyler sonucunda genel olarak 300 ℃ sonrasında basınç dayanımında artışlar tespit edilmiştir. Atık kauçuk agrega kullanılarak üretilen betonların basınç dayanımları, pomza ve perlit agrega kullanılarak üretilen betonlara göre daha düşük olmuştur. Kauçuk atığı kullanılarak yapılan betonun basınç yüklemesi sırasında daha sünek kırılma gösterdiği belirlenmiştir.
