In this study, Dramix RC-80/60-BN steel fiber was added into lightweight concrete of 400 cement dosage in the amounts of 10, 20, 30, 40, 50 and 60. The specimens were tested 28 days later to find the measured apparent specific gravity, concrete strength, modulus of elasticity and toughness value experimentally. Our study concluded that the addition of steel fiber has not changed the concrete strength and modulus of elasticity while it has increased the toughness of lightweight concrete of fixed cement dosage.

Keywords: Lightweight concrete, Steel fiber reinforced concrete, Toughness, Modulus of elasticity.

Bu çalýþmada, 400 dozajlý hafif betona Dramix RC-80/60-BN tipi çelik lifler 10, 20, 30, 40, 50 ve 60 kg/m3 dozajlarýnda katýlmýþtýr. Numuneler 28 gün sonunda kýrýlarak birim hacim aðýrlýklarý, 28 günlük basýnç dayanýmlarý, elastisite modülleri ve tokluk deðerleri deneysel olarak bulunmuþtur. Çalýþma sonucunda; çelik lif katkýsýnýn sabit çimento dozajlý hafif betonun basýnç dayanýmý ile elastisite modüllerini deðiþtirmezken, tokluk deðerini artýrdýðý sonucuna ulaþýlmýþtýr.

Anahtar Kelimeler: Hafif Beton, Çelik lif donatýlý beton, tokluk, elastisite modülü.
