“…Burning, burying, or piling up waste tires in landfills is not only wasteful but also harmful to the environment [1,2]. Given the dense connection among concrete aggregates, wastes such as rubber, plastic, broken ceramic, broken glass, and recycled aggregate can be added to concrete [3][4][5][6]. Among concrete materials, rubberized concrete exhibits good tenacity and energy absorption properties.…”

Adding rubber to concrete aims to solve the environmental pollution problem caused by waste rubber and to improve the energy absorption and impact resistance of concrete. In this paper, recycled rubber particles were used to replace fine aggregates in Portland cement concrete to combine the elasticity of rubber with the compression resistance of concrete. Fine aggregates in the concrete mixes were partially replaced with 0%, 20%, 40%, and 60% rubber by volume, and the cement in the concrete mixes was replaced with 0%, 5%, and 10% of silica fume by mass. The properties of the concrete specimens were examined through compressive strength, splitting tensile strength, flexural loading, and rebound tests. Results show that the compressive strength of concrete and the splitting tensile strength decreased to 11.81 and 1.31 MPa after adding silica fume to enhance the strength 37.8% and 23.7%, respectively, and the dosage of rubber was 60%. With the addition of rubber, the impact energy of rubberized concrete was 2.39 times higher than that of ordinary concrete, while its energy absorption capacity was 9.46% higher. The addition of silica fume increased its impact energy by 3.06 times, but the energy absorption capacity did not change significantly. In summary, the RC60SF10 can be used on non-load-bearing structures with high impact resistance requirements. A scanning electron microscope was used to examine and analyze the microstructural properties of rubberized concrete.

“…On the contrary, there are several drawbacks that accompany the use of plastic in the concrete industry. The compressive strength of all concrete mixtures with plastic decreases as the plastic ratio increases [27,167,168,170,172,177,178]. When cement was replaced by irradiated plastic, only 1.25% replacement by volume led to around 30% reduction in compressive strength.…”

“…Consequently, it reduced CO 2 emissions and decreased the porosity of the concrete samples. As an aggregate substitute, plastic was found to have favorable effects, including the reduction of the cost of concrete [168,169], improvement of the resistance to impact loadings [170], and changing the modes of failure of concrete from brittle to ductile [27,[170][171][172]. One of the most common shapes in the reviewed researches is the shredded shape of waste plastic [173].…”

“…Moreover, plastic reduces the abrasion resistance of concrete due to its plasticity nature [27]. Additionally, when applied to thermal cycles, concrete samples with plastic are inferior to that of controlling concrete samples [170,172]. Nonetheless, special treatments for waste plastic have been implemented in order to decrease the impact of the abovementioned drawbacks in concrete.…”

Green Concrete: By-Products Utilization and Advanced Approaches

The popularity of concrete has been accompanied with dreadful consumptions that have led to huge carbon footprint in our environment. The exhaustion of natural resources is not yet the problem, but also the energy that is needed for the fabrication of the natural materials, in which this process releases significant amount of carbon dioxide (CO2) emissions into the air. Ordinary Portland Cement (OPC) and natural aggregates, which are the key constituents of concrete, are suggested to be recycled or substituted in order to address the sustainability concern. Here, by-products have been targeted to reduce the carbon footprint, including, but not limited to, fly ash, rice husk ash, silica fume, recycled coarse aggregates, ground granular blast-furnace slag, waste glass, and plastic. Moreover, advanced approaches with an emphasis on sustainability are highlighted, which include the enhancement of the hydration process in cement (calcium-silicate hydrate) and the development of new materials that can be used in concrete (e.g. carbon nanotube). This review paper provides a comprehensive discussion upon the utilization of the reviewed materials, as well as the challenges and the knowledge gaps in producing green and sustainable 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. Thorneycroft et al (2018) studied rubberized Portland cement concrete and offered some practical uses of rubberized concrete, including reduction factors.…”

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.
