Özet:

 The composite material obtained by blending cement, aggregate, water and, when necessary, an additive, placing a mixture with carefully adjusted proportions into molds of the desired shape and size without gaps and hardening under appropriate maintenance conditions, is called concrete or traditional concrete. In the 1960s, concretes with compressive strengths of 41 MPa and 52 MPa were used on the market in the USA. In the recent past, concretes with compressive strengths varying between 80 MPa and 100 MPa have been commercially applied in structures made with in-situ concrete and prestressed concrete structural elements. Strength developments of traditional and high-strength concretes under different curing conditions will be examined. For this purpose, central pressure tests were carried out on cube samples produced. For concrete production; For each aggregate class, cement, saturation water, mixed water and high strength concretes; It was prepared by weighing silica fume and superplasticizer. The prepared samples were stored in standard or cold water for 3 days, 7 days, 28 days and 90 days. In this study, the strength development of traditional and high-strength concretes under different curing conditions was examined experimentally. In accordance with the experimental work plan determined for this investigation, concrete cube samples were produced and these samples were subjected to the central pressure test. The concretes produced are in C55, C20 and C12 classes. As a result, although similar behaviors were observed in high-strength and conventional concretes cured in different environments, it was determined that the difference in curing temperature was more effective on the strength development than the inadequacy of curing in water. It should be noted here that it would be beneficial to conduct similar studies on different types of concrete.

 Çimento, agrega, su ve gerektiğinde bir katkı maddesini harmanlayarak elde edilmiş ve oranları dikkatli ayarlanmış bir karışımı, istenen Figure ve boyutta kalıplar içine boşluksuz olarak yerleştirmek ve uygun bakım koşulları altında sertleştirmek yolu ile elde edilen kompozit malzeme beton veya geleneksel beton olarak adlandırılmıştır. 1960larda ABDde basınç dayanımı 41 MPa ve 52 MPa olan betonlar piyasada kullanılıyordu. Yakın geçmişte ise basınç dayanımı 80 MPa ve 100 MPa arasında değişen betonlar, yerinde dökülmüş betonla yapılan yapılarda ve öngerilmeli beton yapı elemanlarında ticari olarak uygulanmıştır. Geleneksel ve yüksek dayanımlı betonların farklı kür koşulları altında dayanım gelişimleri incelenecektir. Bu amaçla üretilen küp numuneler üzerinde merkezi basınç deneyleri gerçekleştirilmiştir. Beton üretimi için; her bir agrega sınıfı, çimento, doyma suyu, karma suyu ve yüksek dayanımlı betonlar için; silis dumanı ve süper akışkanlaştırıcı tartılarak hazırlanmıştır. Hazırlanan numuneler ise 3 gün, 7 gün, 28 gün ve 90 gün boyunca yine standart ya da soğuk ortamdaki su içinde saklanmıştır. Bu çalışmada geleneksel ve yüksek dayanımlı betonların farklı kür koşulları altında dayanım gelişimleri deneysel olarak incelenmiştir. Bu inceleme için belirlenen deneysel çalışma planına uygun olarak, beton küp numune üretilmiş ve bu numuneler merkezi basınç deneyine tabi tutulmuşlardır. Üretilen betonlar C55, C20 ve C12 sınıflarındadırlar. Sonuç olarak farklı ortamlarda küre tabi tutulmuş yüksek dayanımlı ve geleneksel betonlarda birbirine benzer davranışlar görülmüş olmakla birlikte, su içinde kür yetersizliklerinden daha çok kür sıcaklığı farkının dayanım gelişimleri üzerinde etkili olduğu belirlenmiştir. Burada, benzer çalışmaların daha farklı beton türleri üzerinde de yapılmasının faydalı olacağını belirtmek gerekmektedir.
