Ultra-High Performance Concrete (UHPC) is a cementitious, concrete material that has a minimum specified compressive strength of 17,000 pounds per square inch (120 MPa) with specified durability, tensile ductility and toughness requirements; fibers are generally included in the mixture to achieve specified requirements.

This work is aimed to study the performance of steel fiber reinforced self compacting concrete as plain self compacting concrete is studied in depth but the fiber reinforced self compacting concrete is not studied to that extent. Key words: Self compacting concrete, fibers, compressive strength, flexure strength. I Introduction

Technology in concrete has been developing in many ways to enhance the quality and properties of concrete. One of the technological advances in improving the quality of concrete is by using self compacting concrete (SCC). This research was carried out to establish the properties and flexural behaviour of SCC using rice husk

INTRODUCTION Over the last two decades Self-Compacting Concrete (SCC) described as the „„most revolutionary step‟‟ in concrete

While to reduce a noise in a construction project, a self compacting concrete was a good choices in the project. This paper presents an experimental study of flexural behavior and strength of self compacting fiber reinforced concrete (RC) beams using polypropylene fiber. The micro monofilament polypropylene fibers with the proportion 0.9 kg/m 3

admixtures on the workability, compressive strength, and flexural strength of self-compacting concrete was investigated. The mix proportion is obtained as per the rules given by European Federation of producers and contractors of special products for structure. As a result, overall improvements within the flow ability, filling ability

suitability for making self compacting concrete. After the preliminary tests the compressive strength of the mix design (Nan-su-et.al method) of self compacting concrete (M 40 grade) was verified. After testing the compressive strength the fresh concrete were performed for SCC and the mix was found to be satisfying.

ABSTRACT. In the present study, split tensile strength of self compacting concrete with different amount of ZrO 2 nanoparticles has been investigated. ZrO 2 nanoparticles with the average particle size of 15 nm were added partially to cement paste (Portland cement together with polycarboxylate superplasticizer) and split tensile strength of the specimens has been measured.

Introduction In recent developments of concrete technology many special concrete were developed ensuring high strength and high performance characteristics. In that scenario, self compacting concrete (SCC) was

The fibers were aligned along the direction of flow and the alignment properties was justified by flexural strength and UPV. A regression equation was finally developed between flexural strength and UPV for future development, which predicts the behavior of micro steel fiber reinforced self-compacting concrete (MSFRSCC).

Self-compacting concrete is able to overcome the problems through its execution. Moreover, properties of SCC can be further improved via incorporation with other materials. Thus, this study was conducted to investigate the strengths and water absorption of SCC containing metakaolin (MK) and nylon fiber (NF) besides determining the effects of MK and NF in SCC.

Self-compacting concrete (SCC) contains fine mineral fillers such as limestone powder. The idea of this study was to partially replace limestone with waste sulfur since it is hydrophobic, insoluble in water and therefore chemically inert and to compare the properties of produced concrete samples. Fresh concrete proper­ties included: slump-flow, t500, V-funnel time, L-box ratio, segregation

Self compacting Concrete mixtures produced, tested and compared in terms of compressive ,split tensile strength and flexural strength with the conventional concrete for 7,14,28 days. It is found that, 25% of GGBS can be replaced and strength obtained is comparable to the conventional concrete.

Load-deflection curves obtained in flexural tests of self-compacting concrete reinforced with the amount of RSF equal to: (a) 1.0%; (b) 1.5% Regarding the results, the steel fibers from end-of-life tires pronouncedly improved the post-peak mechanical properties of the self-compacting concrete.

Flexural strength is an indirect measure of the tensile strength of concrete. It is a measure of the maximum stress on the tension face of an unreinforced concrete beam or slab at the point of failure in bending. It is measured by loading 150 x 150-mm (or (100 x 100-mm) concrete beams with a span length at least three times the depth.

Flexural strength is one measure of the tensile strength of concrete. It is a measure of an un-reinforced concrete beam or slab to resist failure in bending. It is measured by loading 6 x 6-inch (150 x 150 mm) concrete beams with a span length of at least three times the depth. The flexural strength is expressed as Modulus of Rupture (MR) in

The present work is focussed on the optimization of mix proportions to satisfy the self-compatibility requirements as per EFNARC [march 2006] guidelines and to assess the mechanical properties of concrete made out from these industrial by-products adding partially with GGBS in cement called self compacting concrete (SCC) and concrete made with (GGBS+Fly ash) named as Self Compacting Geo
