The compressive strength at 28 days was also determined. Results show that the slump flow of all FSC mixtures lie between 450 and 840 mm, thus satisfying flowability according the recommendations of AFGC, except for the mixture made with 150 kg/m3 of marble powder (with a slump fl

This study describes two workability tests, compressive strength and tensile strength tests of high strength flowable concrete containing plastic fiber prepared from polyethylene terephthalate (PET) waste bottles.

Results show that there is a Vebe time increase with PET fiber addition to concrete being increased with increasing fiber volume and fiber length. V-funnel time was found to reduce when up to 0.75% fiber volume is added to concrete, followed by an increase for larger fiber volumes. When fiber length is incr

Abstract:
Abstract Self-consolidating concrete (SCC) is one of the trending low-yield stress material innovations of the new age building industry due to its ability to flow through heavily reinforced structural members without segregation and without losing its moderate viscosity. In this research paper, a V-funnel simulation has been developed for the flow time to establish its validity with allowable design conditions according to the European standard. The Bernoulli’s equation and the continuity flow state conditions were adopted for the V-funnel of 515 mm upper width, 75 mm thick, and vertical dime

Abstract:
Self-compacting concrete (SCC) is a type of concrete, which flows under the sole influence of gravity up to leveling, air out and consolidates itself without any external compaction energy. It was a response to the lack of qualified skilled workers at the construction sites and a solution for the accomplishment of durable concrete structures. Self-compactability of a concrete mix is widely affected by the characteristics of ingredients and their proportions. Thus, it becomes necessary to develop a successful procedure for mix proportioning of SCC. The heuristic nature of the early mix proporti

Abstract:
Fresh properties of mortars are important factors in altering the performance of self compacting concrete (SCC). Measurement of the rheological properties of the fine mortar part of concrete is generally used in the mix design of SCC. It can be stated that SCC rheology can be optimized if the fine mortar part of concrete is designed properly. However, measurement of the rheological properties is often impractical due to the need for complex equipment. Therefore, more practical methods of assessing mortar workability are often preferred.

Engineered Cementitious Composites (ECC) are designed by optimizing the matrix, fiber and interface properties according to micro-mechanical steady state cracking theory. Matrix-fiber compatibility in terms of rheology is a pre-requisite for homogeneous fiber distribution. Viscosity enhancing admixtures (VEAs) are frequently preferred in ECC design for an optimized matrix phase viscosity to provide effective fiber distribution.
