Özet
Teknolojinin gelişimi ile çevre kirliliği ve radyolojik etkiler artmıştır. Bu çalışmada, ham perlite agregası kullanılarak üretilen yüksek dayanımlı hafif betonda su-çimento oranının radyasyona etkisi deneysel olarak belirlenmiştir. Ayrıca, beton numunelerin perlit agregalı kütle zayıflama katsayıları belirlenmiştir. Ölçümler, yüksek saflıkta bir germanyum detektörü kullanılarak gerçekleştirilmiştir. Farklı gama ışın enerjileri kullanılarak beton örneklerinin kütle soğurma katsayılarının artan foton enerjileri ile azaldığı gözlenmiştir. Perlit agregası ile elde edilen betonun radyasyondan korunmak için kullanılabilir olduğu ortaya çıkmıştır.
Abstract
The development of technology increases the environmental pollution and radiological effects. In the present work, the radiation effects were determined experimentally, in the high strength lightweight concrete according to water /cement ratio . Also, the mass attenuation coefficients of the high strength lightweight concrete samples which producing with perlite aggregate were determined. The measurements were performed using a high-purity germanium detector. Ten different gamma rays energies were used. It is observed that the mass attenuation coefficients of the concrete samples are decreasing with the increasing photon energies. The concrete obtained with perlite aggregate can be used for protect from the radiation.water /cement ratio .
