Review on Impact of Construction Waste Landfill on Environment and its Reutilization

Abstract

In several countries, the use of recycled coarse aggregate in construction materials is recommended; however, the use of organic matter is restricted because it can produce significant changes in compressive strength. In terms of reaching a conclusive viewpoint regarding the research topic, secondary data collection analysis has been selected. It is essential to utilize the recycled and by-products wastages to prepare alternative materials as this can be useful in generating a significant amount of fine concrete aggregate. As a result, it reduces the extreme exploration of essential natural resources and meets the requirements of natural concrete aggregates by using the alternative and recycled fine concrete aggregate. Moreover, the alternative materials come with similar properties and physical behaviour as they sustain the durability and compound stability of the concrete aggregate through the use of recycled cement. The disposal of industrial wastes can cause extreme environmental harm that can be reduced via recycled cement. However, it has been noted that the presence of harmful materials can result in issues regarding durability. Thus, it is essential to arrange materials for recycled cement that can be effective for construction activities. In order to maintain environmental sustainability and reduce environmental hazards, it is important to utilize the wastages for generating alternative concrete aggregates such as crushed rocks. Thus, this paper reviews the environmental effects of concrete waste pollutants and its sustainable reutilization to promote a cleaner environment and offer benefits to the construction industries with a positive effect.

Sustainable Approach of Utilization of Limestone and Treated Construction Wastes as Aggregates in the Production of High Temperature Resistant Green Concrete

“…Such a higher volume of materials depends on its source from natural raw materials which on surplus utilization leads to scarcity. Such serious concerns about the scarcity of raw materials in construction and the surplus utilization of natural sources have to be addressed with alternative sustainable materials to ensure environmental integrity (Sivamani et al 2022). Limestone aggregates (LA) and recycled aggregates (RA) will be viable options under such circumstances to ensure sustainability in the construction.…”

Enhancing Concrete Recycling in Iran: A Comprehensive Review of Strategies

“…Landfilling concrete waste not only depletes valuable landfill space but also raises environmental concerns due to the potential leaching of pollutants. (Sivamani and Kamaleshwar, 2022) Iran, with its rapidly expanding construction sector, faces a growing problem of construction and demolition (C&D) waste. As estimated by industry experts, Iran generates nearly 120 million tons of C&D waste annually, with concrete constituting a major portion, while landfilling remains the dominant method for C&D waste disposal in Iran.…”

Sustainable Treatment Approach to Dumped Construction Waste with Acids and CO2 for its Effective Re-utilization in Concrete

“…It is observed that treatments to RCA enhanced the quality of RCA. The most inferior characteristics of RCA was its increased porosity subsequent from the mortar smeared on its surface(Sivamani & Kamaleshwar 2022b, Sivamani et al 2021a). The acid impregnation and carbonation to RCA reduced its WA and enhanced the quality of RCA.…”
