Abstract

Superior performances of Self-Compacting Concrete (SCC) in fresh state to achieve a more uniform distribution encourage the addition of fibers in concrete which is a motivation for structural application of fiberreinforced concrete. Fiber addition reduces the workability of SELF-COMPACTING FIBER REINFORCED CONCRETE (SCFRC). To provide required workability of the SCFRC, more paste is needed in the mixture. Therefore, the COARSE AGGREGATE content shall be adjusted to maintain its workability. The purpose of this study is to drive a model for estimating the aggregate contents for SCFRC. This model is based on constant COVERING MORTAR THICKNESS theory. In this paper, all parameters which are participated in COARSE AGGREGATE content are discussed and presented in a relation. Then another relation is developed for predicting the void volume in the fibrous concrete. These relations are combined and a mathematical relation is deduced for predicting the coarse volume content in the function of the fiber factors. Proposed model is validated by conducting a rheological test. The result shows that the proposed model is simple, applicable and can be used as starting point in practical project.Finally in order to complete the proposed model, another relation has been derived that can show the interaction of parameters involved in SCFRC RHEOLOGY behavior.
