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...

This study was conducted to investigate the use of post-consumer corrugated board in controlled low-strength material (CLSM) applications. Corrugated fiberboard (termed corrugate), which constitutes a significant fraction of the municipal solid waste stream in the United States (approximately one third by weight), was used as a partial replacement for fine aggregate in CLSM at aggregate replace...

The production of tailor made high strength and high performance concrete are made by incorporating silica fume into the normal concrete and it is a routine one in the present days. The mix proportioning is intricate and the design parameters are increased due to the incorporation of silica fume in conventional concrete. The aim of this paper is to look into the different mechanical properties ...

Silica fume has been largely used in concrete in recent decades due to its effect on improvement of strength and &#10durability of concrete. On the other hand, attention has been recently paid to the use of limestone powder as a substitute for part of cement in concrete, basically because of its low price and its positive effect on the durability of concrete. The aim of the current study is the...

The unprecedented growth in construction activities have led to speedy consumption of global natural resources like river sand, blue metal, water, and some raw materials like limestone (for producing cement). This study explores the possibility of using Steel-Mesh Reinforced Cementitious Composites (SMRCC) as an alternative to conventional concrete, aiming at sustainability. In order to underst...

1- introductionthe presence of synthetic dyes in water and wastewater causes toxicity to aquatic life and bacteria and changes the brightness, color and clarity of the water. common treatment methods for these compounds are not capable of complete mineralization. therefore, new methods are needed to maximize the efficiency. among them, advanced oxygen processes (aops), especially photocatalytic...

The construction, repair and rehabilitation of concrete pavements relies on the production and flow of large quantities of concrete and its constituents. Within the US, nearly 43 megatons of cement are used annually for the construction, repair and rehabilitation of concrete pavements, accounting for over 39 megatons of CO2 emissions. To reduce environmental impact and improve the sustainabilit...

Water ingress into cracked concrete structures is a serious problem, as it can cause leakage and reinforcement corrosion and thus reduce functionality and safety of the structures. In this study, the application of water-swelling rubber particles for providing the cracked concrete a self-sealing function was developed. The feasibility of applying water-swelling rubber particles and the influenc...

Evaluation of the effect embodied carbon reduction using an optimized design section for a ground beam, use supplementary cementitious materials, and replacement normal aggregate with light weight on mechanical properties low-carbon concrete was carried out. A creep coefficient 0.019 estimated 365-day period change in from 1 to 0.6 m2 proposed trapezoidal which showed negligible difference when...
