Polypropylene Fiber Reinforced Concrete is an embryonic construction material which can be described as a concrete having high mechanical strength, Stiffness and durability. By utilization of Polypropylene fibers in concrete not only optimum utilization of materials is achieved but also the cost reduction is achieved. This paper presents a comprehensive review on various aspects Polypropylene F...

Concrete durability, especially in water-logged environments might not be possible with conventional constituents of concrete. A combination mineral and chemical admixtures different proportions is used to study water absorption, sorptivity, permeability behavior The test were carried out using nine (9) trial mixes Calcined Clay (CC), Sawdust Ash (SDA), Crystalline Based Admixture (CBA), Superp...

Many concrete structures have been constructed in Japan. Some concrete structures show severe deterioration and need repair or strengthening to keep their serviceability. Development of strategic maintenance is the highest priority under the background of aging of huge amount of stock of concrete structures and restrained budget. Public Works Research Institute has been undertaking comprehensiv...

In most cases, structural engineers assume a concrete floor to be a rigid diaphragm. Although this simplification is in most cases acceptable, it should be noted that such an assumption may be distrusted due to certain problems. Concrete structures with staggered shear walls are among those whose analysis should be conducted with special concern for the behavior of their floor diaphragms. Howev...

The problems of degradation concrete and reinforced constructions buildings long operation are formulated on the basis performed field researches its urgency is noted in work. authors analyzed a number works this problem. In particular, results technical diagnostics many structures, both newly built long-term operation, described. necessity periodic noted. Based these studies, main factors that...

In recent years, there is increasing interest in the phenomenon of mechanical property recovery in concrete construction using self-healing concrete. The study was motivated by the need to find a solution for the problem of cracking approaching the concept of self-healing concrete. The study was carried out on a bacteria based self-healing concrete using Bacillus Subtilis bacteria. The present ...

The sustainable development goal (SDG) 14 of the 2030 Agenda for Sustainable Development aims at protection, conservation, and management coastal ecosystems resources, including by strengthening their resilience, to avoid significant adverse impacts. Coastal/marine structures are exposed aggressive environmental conditions, such as chloride laden environment. Deterioration reinforced concrete l...
