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...

The utilisation of biochar, the carbon negative product pyrolysis, reduces footprint cementitious composites as it possesses potential to replace consumption Portland cement. In a systematic investigation, biochar was used partial cement replacement for up 20 wt% in both pastes and mortars. A comprehensive experimental framework conducted evaluate impact on performance (i) paste terms hydration...

Engineered Cementitious Composites (ECCs) are novel cement-based ultraductile materials which is crack resistant and undergoes strain hardening when loaded in tension. In particular, the material is piezoresistive with changes in electrical resistance correlated with mechanical strain. The unique electrical properties of ECC render them a smart material capable of measuring strain and the evolu...

Engineered cementitious composites (ECC) is distinct for the tensile strain-hardening behaviourand ductility contrasting to quasi-brittle nature of ordinary concrete. The blended materials ECC only consist cement, sand, water, fibre, and admixture. depleting limited resources sand in many countries have led research on alternative replace partially or fully concrete mixture. Therefore, this stu...

Cement-based materials are widely used in the construction of civil infrastructure systems. However, normal wear-and-tear and extreme loading can result in the damage and deterioration of such important civil structures. In this study, a novel approach to the detection of cracks in fiber reinforced cementitious composites (FRCC) is proposed. The approach is based upon the electrical properties ...

With the advent of strain-hardening cementitious composites (SHCC), an opportunity for alternative jacketing solutions is presented, where internal confinement exerted by fibers in material may effectively encase structural component, thereby enhancing strength and deformation capacity critical regions. This concept explored present paper through testing four pre-damaged prismatic flexural rein...
