Concrete production is widely recognized for its substantial environmental footprint throughout its life cycle, primarily attributed to the extensive utilization of natural aggregate. ... which advocate for zero waste production through the comprehensive reutilization of secondary raw materials via recovery and recycling methodologies. This ...

Concrete, the second-most-consumed man-made substance on Earth after water, is widely used in the construction industry at a global production rate over 3.8 tonnes per capita per year (Gursel et al., 2014).The essential constituent of concrete, cement, is highly energy-and-emissions intensive due to its production that accounts for approximately 5 percent of the …

The natural materials utilized in concrete are non-renewable so the depletion of natural materials is the need for using some waste products in the concrete as a substitute material ...

As a man-made geomaterial, concrete serves as a potential CO 2 sink through mineral carbonation. The enormous resource flow involved in concrete production offers a plausible opportunity to leverage large-volume CO 2 sequestration (GCI, 2016).The past decade has witnessed a global surge of interest in integrating CO 2 as an ingredient into various …

For resource reutilization, scrap tyres have long been investigated as an additive to concrete to form 'Rubcrete' for various applications and have shown promising results. However, the addition of rubber particles leads to the degradation of physical properties, particularly, the compressive strength of the concrete.

The concrete blocks were prepared with an aggregate to cement ratio of 12, 10 and 6. The pretreated TES was adopted to replace the fine aggregate at a mass ratio ranging from 0% to 30%. ... (Gencel et al., 2013) and CRT funnel glass (Ling and Poon, 2014). Recently, reutilization of sewage sludge ash (SSA) was reported to manufacture blocks with ...

Engineers are still unsure as to what extent waste can be repurposed to produce optimal strength for the production of concrete. Reutilization of waste materials has been employed in this paper by adopting 3.5%, 7%, and 10% of six wastes (plastic bags, rubber tires, cement sack strands, can waste, PET bottles, and waste from glass) as ...
