“…F.S. Khalid et al 2018 used the plastic wastes as manufactured synthetic macro-fibers in RC beams, which show the better behavior in cracking stage, concrete beams containing 10% plastic fibers showed that the strength of the first crack improved by 32.3% compared to normal concrete beams [17]. Brahim Safi et al 2013 stated that Reduction in the compressive strength was between 15% and 33% for mortar containing 20-50% plastic waste, and the mortar containing up to 50% of plastic waste was acceptable for lightweight mortars with the bulk density 1.5 kg/m 3 [21].…”

For its favorable properties and easily availability, the use of concrete increasing annually. When the concrete exposed to environment it start to disintegrate due to chemical attack. The chemical attacks on concrete majorly are in the form of a reaction between aggressive agents and the cement matrix, although reactions can also happen with the aggregates. This review paper gives a suggestion to make a cost effective and durable concrete to perform well in the aggressive corrosion environment by the waste products obtained from different industry. The use of Portland cement concrete has an impact on the environmental due to the emission of CO2 in the atmosphere. On the other side handling of plastic waste was a major problem all over the world. So, as to give suggestion to these problems the study has been made as the use of rice husk ash (obtained from agricultural waste) and silica fume (obtained from alloy industry) as partial replacement of Portland cement to increase strength at early and later ages. And due to its micro structure it reduce the permeability of concrete and exhibit considerable enhancement in durability, also provides better bond between cement matrix and the aggregate. The usage of LDPE is high throughout the world compared to other plastics, the density of LDPE range from 925-940 kg/m 3 so the density of the concrete greatly reduce up to 30% as their wastes can be used as a replacement for fine aggregate.. In terms of durability the high amount of silica impregnated the concrete samples and thereby reduces porosity of concrete. The strength reduction due to plastics will nearly compensated by the RHA and SF. The use of such waste products gives cost effective and reducing co2 emission and best method for the disposal of plastic wastes.

“…The development of the construction sector imposes the finding of some solutions of using cheaper materials, locally, considering the magnitude of the sector, it requires the consumption of natural aggregates, binders, armatures, etc., which are difficult to ensure from traditional sources [1][2][3][4][5][6][7][8][9]. It must equally be ensured that the exigencies (safety, durability) must be met throughout the entire life span of the construction [1,2,[10][11][12].…”

“…In reinforcing concrete, fibers are increasingly used because they provide control of the cracking process and increase the resistance to impact, shocks and temperature variations [1,2,[10][11][12][13][14][15][16][17][18]. Fibers can be used in the preparation of concrete for different building elements, including rigid concrete structure, pedestrian and concrete pavements and borders, support walls or bulwark foundations, but they are starting to be used more and more in the production of prefabricated [1][2][3][4][5][6][7][8][9][10][11][12].…”

Woven fiber reinforced concrete is a material, which contains various quantities of polymer materials in composition, in addition to the conventional components of an ordinary concrete (mineral binder - cement, aggregates, water and additives). The present work refers to the concrete in which the reinforcement is made of polymeric materials (polyethylene terephthalate), originated from the recycling programs of PET-type packaging. The experimental program was aimed at constructing some samples of woven fiber reinforced concrete from recycled material coming from PET packaging wastes, their testing to the compression demands and the comparison of results with the characteristics of the standardized samples of concrete (class C30/37). Based on a sufficient number of determinations, certain correlations can be established between the compressive strength of the concrete at 28 days depending on the dosage of components (aggregate, binder, and reinforcement), water / cement ratio, reinforcement volume, etc., essential parameters from a compositional point of view. These correlations, customized by cement type and strength class, are very important to determine - with approximation - to what dosage of components (aggregate, binder, reinforcement) the respective level of compressive strength of concrete is obtained.

“…The importance of recycling of waste tires coupled with the interest in overcoming the aforementioned concrete defects have motivated a significant body of research pertaining to rubberized concrete. Properties, testing and design of rubber as an engineering material were investigated in 1960 (Khalid et al, 2018;Yin et al, 2015;Segre and Joekes, 2000). Saxena et al (2018) and Segre and Joekes (2000) used tire-rubber particles as concrete aggregates, elucidating rubberized concrete properties and proposed an analytical approach to predict the strength in rubberized concrete.…”

Solid waste management is one of the major environmental concerns all over the world and in Kuwait. Over 5 billion tons of non-hazardous solid waste materials are generated in Kuwait each year. Of these, more than 2 million scrap-tires (approximately 2 million tons) are generated each year. In addition to this, about 7 million scrap-tires have been stockpiled. Due to the increasingly serious environmental problems presented by waste tires, the feasibility of using elastic and flexible tire-rubber particles as aggregate in concrete is investigated in this study. Tire-rubber particles composed of tire chips, crumb rubber and a combination of tire chips and crumb rubber were used to replace mineral aggregates in concrete. These particles were used to replace 10, 15, 20 and 25% of the total mineral aggregate's volume in concrete. Concrete cubes with dimensions of 100×100×100 mm 3 and prisms with dimensions of 75×75×300 mm 3 have been prepared and tested for their compressive strength. It was observed that, increasing the tire-rubber content, reduces the compressive strength, the unit weight and density of the concrete compared to plain concrete. Moreover, modulus of elasticity decreases as waste crumb tires replacement increases. The study concludes with useful comments and suggestions.
