ID No: 136 Abstract: Cracks are inevitable for concrete infrastructures during their service life. The presence of cracks reduces the mechanical properties and bring potential safety hazard to infrastructure. In this study, the influence of self-healing on the ECC’s (Engineered cementitious composite) tensile properties was investigated. ECC is a new kind of HPFRCC, featuring high strain capaci...

Prolonging the life of reinforced concrete structure is most promising solution to reduce carbon emissions from concrete. To achieve that, should be protected crack formation, which acts as an easy pathway for deleterious agents. Self-healing technologies are intended provide long-term resilience against cracking due various deterioration processes. Technologies that performed well in small, la...

This paper investigates the autogenous self-healing capability of conventional concrete (C30/37) mixtures with water encapsulated in sepiolite. Sepiolite was added two conditions: previously saturated and dry, at a dosage 5% by cement weight. is substitution for sand fraction. For these mixes reference mix without sepiolite, disks size f100x50 mm were produced pre-cracked 28 days age splitting ...

Autonomous crack healing of cementitious composite, a construction material that is susceptible to cracking, is of great significance to improve the serviceability and to prolong the longevity of concrete structures. In this study, the St-DVB microcapsules enclosing epoxy resins as the adhesive agent were embedded in cement paste to achieve self-healing capability. The self-healing efficiency w...

The corrosion of reinforced steel, and subsequent reinforced concrete degradation, is a major concern for infrastructure durability. New materials with specific, tailor-made properties or the establishment of optimum construction regimes are among the many approaches to improving civil structure performance. Ideally, novel materials would carry self-repairing or self-healing capacities, trigger...

The increasing awareness of climate change and global warming has pushed industries to be more conscious their environmental impact, especially in the construction industry with main contributor being concrete. Concrete is a material that very high demand for structural applications. However, it’s major concern challenges microcracking. New technology seen development self-healing material, usi...

In the present study, rarely explored spore former (Bacillus safensis & Bacillus pumilus) and non-spore (Arthrobacter luteolus, Chryseomicrobium imtechense Corynebacterium efficiens) alkaliphilic calcifying microbes were evaluated for their prolonged survival in cementitious environment. Extensive experimental program was designed to examine mechanical, self-healing, microstructural modificatio...
