Throughout the world, the disposal of used tires is a major environmental problem causing environmental hazards such as breeding ground for mosquitoes, producing uncontrolled fire and they are contaminating the soil and vegetation. Therefore, there is an urgent need to identify alternative outlets for these tyres, with the emphasis on recycling the waste tyre. Concrete is an excellent structural material and considered as essential for the modern civilization and human society. Now, the use of waste tires in concrete has become technically feasible and the concrete is being considered as light weight concrete. This study reviews the feasibility of using waste tires in the form of chips and fibers with different sizes in concrete to improve the strength as well as protecting the environment. Also it reviews the potential application in the field by exploiting its unique characteristics and properties. In this study, we outline the use of rubberized concrete in structural and non-structural members and show how it is suitable for the concrete, its uses, barriers and benefits and way to future study.

The ability to view constructions virtually before using the real resources to construct them has been of main interest in civil engineering over a long period of time. This has been achieved partially through virtual reality. Virtual Reality helps in visualizing the operations on computer generated jobsites and to study the available alternate plans. Even though the latest software in virtual reality helps us in designing and drawing the plans, the question of reality still arises. The plans that are done in computer sometimes do not match with the real practical applications. This shows that it is difficult to bring the experiences of practical world into the computer. In order to overcome the gap between the real and virtual environments, this paper highlights the use of Augmented Reality (AR) in all the areas of civil engineering instead of using Virtual Reality. This paper describes the developing augmented reality technology and its various application domains in civil engineering.

Over the last couple of decades, the interest in using advanced high performance materials in the construction industry has been shooting up and developing to reduce the overall life-cycle costs of structures. Accordingly, many researches have been carried out to invent new materials which possess the properties comparatively more advantageous than conventional steel reinforcements. Fibre Reinforced Polymer (FRP) reinforcements are considered as new, high tech and ideal materials optimistically used in many countries in the construction field especially in the construction of bridge deck slabs. So many researches have been done to assess the mechanical properties of FRP reinforcements , flexural and shear behaviours of FRP reinforced structural elements under static or monotonic loading. But only limited works have been brought out on the fatigue performance of FRP reinforced structural elements. This paper presents the flexural behaviour of one-way slabs reinforced with Glass Fibre Reinforced Polymer (GFRP) reinforcements (special type of FRP reinforcements) under monotonic loading and two different schemes of repeated loading. A total number of twenty one GFRP reinforced concrete one-way slabs were constructed, out of which seven were tested under monotonic loading, seven were tested under constant amplitude repeated loading and the remaining seven slabs were tested under variable amplitude repeated loading conditions. The behaviour of GFRP reinforced slabs were compared with that of steel reinforced slabs. It has been found that the ultimate load carrying capacities and fatigue performance of GFRP slabs were greater than that of steel slabs. Also there exists a good agreement between the theoretical and experimental results.
