Bendable concrete also known as Engineered Cementitious Composites abbreviated as ECC is class of ultra-ductile fiber reinforced cementitious composites, characterized by high ductility and tight crack width control. This material is capable to exhibit considerably enhanced flexibility. An ECC has a strain capacity of more than 3% and thus acts more like a ductile metal rather than like a.
Engineered Cementitious Composite (ECC) is a material which is commonly known as bendable concrete. This material exhibits some ductile behavior that resists cracking; its ductile nature could make it of important use in protection and repair of structures.
This paper focuses on the application of ECC as a method of rehabilitation for rigid pavements. Rigid pavements have the shortcoming of. weak bendable concrete shows effective results on flexural values by partial replacing cement with fiber- recron fiber and flyash is partially replaced with cement by different percentages 10% 20% and 30%. The mix shows different strength for percentages of fly ash and dose of recron fiber in each mix. Keywords: Bendable Concrete, Engineered Cementitious Composites (ECC), Recron fiber.
I. Composites) or Bendable concrete, Poly Vinyl Alcohol, fibre, Super plasticizer. I. INTRODUCTION POLY VINYL ALCOHOL FIBER (PVA) While selecting fibres for ECC, it was found that polyvinyl alcohol (PVA) fibre was of low cost and high performance.
The hydrophilic nature of PVA fibre imposed great challenge in the composite design, as the fibres are susceptible to rupture instead of being pulled. bendable concrete has a strain capability within the range of 3 to 7 percent when compared to % for ordinary Portland cement (OPC). It also acts more like a ductile metal than a normal OPC concrete which acts like a brittle glass.
That's why it leads to wide applications. In this research there have been 1 standard concrete batch mix of total 36 samples and 3 partially concrete batch mix.

ECC acts more like a ductile metal than a brittle glass which. A flexible or bendable concrete is an engineered cementitious composite (ECC) that exhibits the property of ductile material unlike the brittle nature of conventional concrete. The material composition of conventional concrete is altered in order to impart flexible nature in concrete. The flexible or bendable concrete was developed by Prof. Victor Li at the University [ ]. Composition of ECC • Bendable concrete is composed of all the ingredients of a traditional concrete minus coarse aggregates and is reinforced with polymer fibres.
• It contains cement,sand, water, fibres, and admixtures. • Polyvinyl Alcohol-fibres covered with a very thin (nanometer thick), slick coating which prevents the fibre from eypq.xn----7sbbbvr4armackn9b.xn--p1ai ECC deforms much more than a normal.
This new bendable concrete makes streaming less labor-intensive through simple materials. It can be made into slim concrete asphalt plates. Scientists said these plates could reduce the time taken to develop roads. Working Of This New Bendable Concrete: Generally, traditional concrete uses gravel, sand, cement, and water. But this combination makes the mixture durable but not.

Different types of reinforcement fibres used in Bendable Concrete Slick coating (anti-friction coating): Additionally the slick coating (anti-frictional coating) is provided so that the fibers particles can slide over one another and does not have the friction which may result into the cracks in concrete. This tendency of slipping of fibers over one another helps the concrete to minimize the.

Bendable Concrete Victor C. LI1 1 University of Michigan, USA Concrete is arguably the most important construction material.
Since its early days, concrete has always been known as a material strong in compression, but tends to be brittle in tension. While the use of steel reinforcement has made concrete highly effective in large-scale constructed facilities, improvement in resiliency.

applications and scope in various fields of Civil Engineering. SCOPE AND BACKGROUND Concrete is the most important construction materials used worldwide. Historically, structural designers have primarily relied on concrete to carry compressive loads. However, in real field conditions, concrete is also subjected to tensile stresses due to loading and environmental effects including. Bendable concrete also known as “Engineered Cementations Composites” (ECC) is a class of ultra-ductile fiber reinforced cementitious composites, characterized by high ductility and tight crack width control.
In this concrete, we eliminate the coarse aggregate. Instead of that, we use fibers such as silica fiber, steel fibers, Asbestos fiber, polyvinyl alcohol fibers etc. to provide. particularly suited for applications in wet environments where reinforcement corrosion tends to impede durability of traditional concrete constructions. Keywords: Concrete crack-healing, permeability, bacteria, calcium carbonate formation 1 Introduction Crack formation in concrete is a phenomenon that can hardly be complete avoided due to for example shrinkage reactions of setting concrete and.
Bendable concrete also enables structural elements to absorb a lot of energy. For example, manufacturers have developed ECC dampers to retrofit the 28 kilometer Seisho Bypass viaduct along Japan’s eastern seaboard and to help make new tall buildings more resilient during earthquakes, including several in Tokyo and Osaka.
Bendable concrete is one step closer to hitting the market. Bendable concrete or E ngineered Cementitious Composites (ECC) were originally developed. bendable concrete puzzle. Used Around the World ECC is used in building and infrastructure projects in several countries. First Application in U.S. MDOT uses ECC on bridge in Ypsilanti, becomes first in U.S. to use it on transpor- tation infrastructure. New Challenges, New Opportunities Unexpected cracking makes clear the need for holistic approach to design.
Inherently Sustainable Use of. Engineered Cementitious Composite (ECC), also called Strain Hardening Cement-based Composites (SHCC) or more popularly as bendable concrete, is an easily molded mortar-based composite reinforced with specially selected short random fibers, usually polymer fibers. Unlike regular concrete, ECC has a strain capacity in the range of 3–7%, compared to % for ordinary portland cement.

Although some researchers have studied the application of PVDF for energy harvesting from regular RC infrastructures or renewable sources such as wind and water droplets, little research has been done to investigate its application in energy harvesting through bendable construction materials.
This research proposes to utilize a piezoelectric energy harvesting structural system using Cited by: 9. Lightweight Concrete. It may be defined as the concrete of substantially lower unit weight than that made from gravel or crushed stone. Light Weight Concrete Wall Panels. Ordinary concrete is quite heavy and its density is kg/m3. It is not suitable for use in floor filling as filler in general. If used, it adds considerably to the dead weight of the structure.
By using suitable. The ingredients in any particular mix depends on the nature of the application. Regular concrete can typically withstand a pressure from about 10 MPa ( psi) to 40 MPa ( psi), with lighter duty uses such as blinding concrete having a much lower MPa rating than structural concrete. Many types of pre-mixed concrete are available which include powdered cement mixed with an aggregate. A bendable concrete is reinforced with micromechanically designed polymer fibres.
The aim of this study is to investigate the hardened property (i.e. Flexural Test) of ECC by addition of Steel, PVA & Hybrid fibers in different proportion. The result of Flexural strength of various ECC mix with different percentage of fibers are compare with Conventional Concrete design according to Indian.
