Yüksek mukavemetli beton (HSC) ve köpük beton için izin verilen katkıların in vitro değerlendirilmesi
Abstract
Malzeme bilimindeki
önemli ilerlemeler sayesinde araştırmacılar, yüksek mukavemetli beton (HSC) ve
köpük beton gibi yeni beton teknolojilerinin uygulanmasına orantılı olarak
farklı beton tipleri üretip geliştirmeyi başardılar. Bu yazıda köpük beton ve
uygulamaları üzerine deneysel çalışmaların sonuçları sunulmaktadır. Ayrıca
çimento içeriği, su / çimento oranı ve katkı maddeleri gibi çeşitli
parametrelerin etkisi karışım tasarımında incelenmiştir. HSC'de beton kurucu
maddeler arasındaki etkileşim, betonun mekanik özelliklerinde ve basınç
dayanımında önemli rol oynamaktadır. Bu nedenle, bu faktörlerin uygun bir
şekilde anlaşılması, istenen davranış ve dayanıklılığı olan bir betonun
yapılması için uygun tür ve miktarda malzemeyi seçmemize yardımcı olur. Çalışmada
kullanılan yöntemler ve teorik prosedürler ACI kodlarına dayanmaktadır. Bu
çalışma, HSC'nin mukavemetine Micro Silica ve plastikleştiricilerin
kullanmasının etkisini araştırmayı amaçlamaktadır. Elde edilen sonuçlara göre,
beton karışımı tasarımı için kullanılan optimum oran ve bu malzemelerin beton
mülkiyet üzerindeki olumlu etkileri doğrulanmıştır.
