Synopsis: Cementitious materials are generally classified as semi-conductors that are capable of carrying electricity when an external electrical signal is applied. The electrical properties of cementitious materials have been widely explored for monitoring their internal hydration processes. However, comparatively less work has been done in using the inherent electrical properties of cementiti...

An analytical model that allows prediction or reproduction of the overall stress-strain relationship of a high performance cementitious composite in tension is presented. Through consideration of stochastic character of the composite microstructure, the model captures the sequence of crack formation and the load fluctuations that are characteristic for the process of multiple cracking. The prop...

An engineered cementitious composite (ECC) suitable for wet-mixture shotcreting (sprayable ECC) in the fresh state, while maintaining tensile strain-hardening behavior in the hardened state, has been developed by employing a parallel control of micro-mechanics-and rheology-based design. In the development concept of sprayable ECC, micromechanics is adopted to properly select the matrix, fiber, ...

An extrusion process especially designed for extrusion of pipes made from fiber reinforced cementitious materials has been developed at Department of Structural Engineering and Materials at the Technical University of Denmark. Engineered Cementitious Composite (ECC) materials have been developed in recent years at Department of Civil and Envirionmental Engineering, University of Michigan. These...

In recent years, a new class of cementitious composite has been proposed for the design and construction of durable civil structures. Termed engineered cementitious composites (ECC), ECC utilizes a low volume fraction of short fibers (polymer, steel, carbon) within a cementitious matrix resulting in a composite that strain hardens when loaded in tension. By refining the mechanical properties of...

In this paper, the development of a new variation of Engineered Cementitious Composite (ECC) that aims to combine tensile ductility with self-sensing ability is described. ECC is a new type of high-performance fiber reinforced cementitious composite that exhibits strain-hardening under applied tensile load while resisting fracture localization. The self-sensing ability is achieved by incorporat...

This article describes design concept and material characteristics of a new ductile fiber reinforced cementitious composite referred to as ECC (Engineered Cementitious Composite). This particular ECC contains Polyvinyl Alcohol fiber and exhibits remarkably ductile tensile property with over 1% of tensile strain capacity. The high tensile strain performance of the ECC was found successfully util...

This paper introduces the concept of Integrated Structures and Materials Design (ISMD). ISMD combines materials engineering and structural engineering for the purpose of more effectively achieving targeted structural performance, by adopting material composite properties as the shared link. An application example, design of a bridge deck link-slab, is used to illustrate the essential elements o...

The purpose of the present research is to assess impact foundry sand (FS) and cement kiln dust (CKD) on autogenous shrinkage, drying total shrinkage engineered cementitious composites (ECCs) over 100 d. Additionally, pore sizes their distribution in developed ECC system were assessed through BJH adsorption technique. findings showed that structure was refined continuously time. This indicates C...

Engineered cementitious composite (ECC) is a new generation of fiber-reinforced concrete with high ductility and exceptional crack control capabilities. However, ECC can suffer substantial reduction in when exposed to elevated temperatures resulting loss crack-bridging ability. In this study, the effect adding basalt fiber (BF), which an inorganic high-temperature resistance for production ECC,...
