Evaluation of Shear and Tensile Bridging Characteristics of PVA Fibers Based on Bridging Lawentitious material because fibers bridging the crack transfer tensile forces after first cracking. It is considered that the stress field at the shear crack surface in the structural element under the shear force is a biaxial stress field in which tensile and shear stresses exist concurrently. In fi

Mechanical Properties of Ductile Cementitious Composites Incorporating Microencapsulated Phase Changns have been proposed, mainly utilizing fibres. One of the most promising classes of materials is strain hardening cementitious composite (SHCC). It utilizes PVA fibres, and it relatively costly compared to regular concrete, so it is commonly used only in surface layers. This paper presents a multi-

A Comparative Study on Deflection-Hardening Behavior of Ductile Alkali-Activated Compositeovide high potential for waste reutilization. Alkali activated materials (AAMs) generally exhibit better durability and comparable or superior mechanical performance in comparison to traditional cementitious materials. However, like cementitious binders, AAMs are inherently brittle (quasi brittle).

Influence of Coarse Aggregate on the Mechanical Behavior of Strain Hardening Cementitious Compositesmaterial and structural level. In the experiments, maximum size and volume fraction of coarse aggregate were varied as parameters. Direct uniaxial tensile tests and bending tests were carried out in order to evaluate the mechanical performance such as tensile strength and elongation capacity of SHCC

Development of Cementitious Composites with Tensile Strain Capacity up to 10%er fibers, the normal SHCC have the tensile strength ranging from 3?MPa to 7?MPa and the tensile capacity about 3%–6%. Nevertheless, such level of ductility is not sufficient to make the material free from steel reinforcement in case of constructing structure likely to be subjected to extreme condit
