This research aims to investigate the most efficient and potential steel fiber among all four i.e. hooked, crimped, twisted straight, that contributes in boosting performance quality of concrete after extensive examinations. Several mixes were examined, incorporated with fly ash (FA) metakaoline (MK) various proportions FA15%+MK4.5%, FA20%+MK9%, FA25%+MK13.5%, FA30%+MK18% each composition is re...

This paper discusses the concept of self-consolidating concrete mix with Alccofine-1203, superplasticizer, viscosity modification agent, crimped steel fiber on RC beam column joint. Totally, eight reinforced-concrete (RC) joints M25 grade were considered in this study. Out joints, two served as Alccofine, joint specimens Alccofine 5%, Alccofine-10%, and Alccofine-15%. All tested under compressi...

The slurry infiltrated fiber concrete (SIFCON) is nowadays considered a special type of high content concrete; it strength and performance material. This paper investigates the effect spread steel into mortar on some properties SIFCON. According to distribution, two sets were used in this investigation. first set consisted randomly distributing fibers inside slurry. second was by placing an ord...

OBJECTIVES It is not clear what type of pre-crimped crown is more successful in achieving greater marginal adaptation following re-crimping. This study aimed to assess the changes in the circumference of 3M ESPE and MIB pre-crimped stainless steel crowns (SSCs) for the primary maxillary and mandibular first and second molars following re-crimping. MATERIALS AND METHODS This was an in-vitro, e...

In this paper, modeling of high speed projectiles with different nose shapes, penetrating into steel fiber reinforced concrete is investigated. This is a novel study because it considers the length to diameter ratio of steel fiber as well as projectile length to diameter ratio and volume fraction of fiber used in concrete matrix on the impact resistance of steel fiber reinforced concrete fibers...

In the present study, a new method for retrofitting reinforced concrete beam is introduced in which steel-concrete composite jackets containing steel fiber is used. For this purpose, 75% of the peripheral surface of reinforced concrete beams was initially reinforced using steel plates and bolts, and steel fiber reinforced concrete was used between the steel plates and the peripheral surfaces of...
