Abstract
Randomly taken samples of Trass Cement (TC-32.5, according to TS-26) produced by a cement factory nearby Kayseri, and fine and coarse groups of crushed stone aggregates and natural sand were taken at sufficient quantities. Specific gravity and gradation tests on aggregates in accordance with the Turkish Standards: TS-706, TS-707, TS-3526 and TS-3530 were performed. Concrete mixes were designed according to TS-802. Test batches were prepared and tests on fresh and hardened concrete mixtures were done in compliance with TS-3068, TS-2871 and TS-3114. With a constant mix water of 177 kg/m3 , which yielded a slump of 10 ~ 12 cm, for aggregates in saturated-surface-dry condition, three different batches with dosages of 250, 300 and 350 kg/m3 were prepared and tested. In conclusion, it was determined that concrete classes of BS-20 and BS-25 could be produced with reasonable cement dosages, provided that they are properly mixed and cured.
Özet
Kayseri'de traslı çimento üreten bir fabrikadan TÇ-32.5, ve Kayseri'de kullanılan ince kırmataş, iri kırmataş ve doğal kumdan yeterli miktarlarda numuneler rastgele olarak alınmıştır. Agregalar üzerinde TS-706, TS-707, TS-3526 ve TS-3530'a göre deneyler yapılmıştır. TS-802'ye göre reçeteleri hesaplanan betonların deneyleri TS-3068, TS-2871 ve TS-3114'a göre yapılmıştır. 10 ~ 12 cm taze beton çökmesi veren kıvamda 1 m3 beton için agregaların "doygun kuru-yüzey" hallerinde 177 kg karışım suyu ile 250, 300 ve 350 dozlu deney betonları karılmış, 6'şar adet 15x30 cm'lik silindir numunelerin beton presinde kırılması sonucu mukavemetler ölçülmüş ve BS-20 ve BS-25 sınıfı betonların makul çimento dozajları ile elde edilebileceği bulunmuştur.
