“…The eggshells contain a limestone or calcium carbonate usually called calcite (CaCO3) [25,26]. Eggshell ash (ESA) is another bio-waste material that can be utilized to reduce the cement in concrete production [27]. Eggshells, the byproduct of eggs utilization, can establish an irritation in our current circumstance through unpredictable removal [29].…”

The application of chemical stabilizer in soil stabilization can effectively reduce the negative environmental impact in the construction industry. However, the stabilization of soft clay remains a challenge due to the costly and non-eco-friendly materials such as cement and lime. This research demonstrates the combination of SF and ESA in stabilizing the kaolin soils, based on the basic engineering properties and undrained shear strength (USS). Its effect was studied via the inclusion as cement replacement material in kaolin soil at 2, 4 and 6% (by weight of dry soft kaolin clay soil) of SF and ESA substitutions of 3, 6 and 9% (by weight of dry soft kaolin clay and SF content). The result shows a considerably lower specific gravity (4.9% reduction), reduced plasticity index (PI)(48.4% reduction), decreased maximum dry density (MDD) (5.5% reduction), increased optimum moisture content (OMC)(8.7% increment), and higher USS (68.8%). In conclusion, the combinations of SF and ESA as soil stabilization agents successfully enhance the soil strength of the kaolin opening a route to the low cost and eco-friendly materials in soil stabilization.

“…Partial replacement of granite with coconut shell from 0 to 100% in increment of 25% was considered for the mix. Rice husk ash and Silica fume were considered for creating binary and ternary mix of self-combining concrete with total powder content of 450 kg/m 3 and 550 kg/ m 3 . The 75% CSA in 28 days reflected on the compressive strength, more than 21.72 MPa as observed it satisfies the necessities of lightweight concrete [65].…”

“…The use of waste materials as workable alternative to the traditional material in concrete has increased popularity in current years, which is due to the overexploitation of the natural material sources [1][2][3]. Waste utilization in concrete has two advantages, discarding of waste in green manner and improving strength and durability properties of concrete [4,5].…”

Sustainable building technology is a new approach adopted in built environment, which is focused on significantly reducing impact of the construction industry on the environment. Moreover, the world is largely driving development of sustainable and smart products to mitigate global pollution issues. In this study, assessment of the impacts of using alternative constituents such as crumb rubber, coconut shell, recycled aggregate, GGBS, human hair, banana fiber, industrial sludge, saw dust, rice husk, wood waste, textile, copper slag, textile, glass powder, plastic etc., on concrete strength development using case studies has been performed. The paper explores the research work carried out towards sustainable approach in replacement of basic composition of concrete. It focuses on various waste materials used as a substitute options in concrete and characteristic strength development along with potential challenges. Leading researches relating to sustainable materials were also explored. The results show that the alternative aggregates, mostly with minimally usage of about 20% increased the compressive strength properties of concrete. Usage of fibres to about increased the flexural property of concrete and the replacement of waste sludge didn't show appreciable increased of compressive strength.

“…Authors Zhao, Gao, and Yang (2020) explained that the production of a quantity of cement generates almost the same quantity of CO2 gas that causes ecological damage, indicating that the manufacture of concrete has a considerable influence the environment and health (Haza, Shulhan, & Kadis, 2020). Likewise, Hamada et al (2020) investigated that cement consumption in 2010 was 3.27 billion metric tons and is expected to rise to 4.83 billion metric tons in 2030, possibly causing climate change. The conservation and protection of the environment had become a problem of global context, for which since the world summit of the earth in 1997 in Kyoto Japan the need to reduce CO2 emissions on a large scale was created (objective before 2010 was to reduce by approximately 21%) to avoid a global catastrophe, large industries and countries around the world agreed to formulate a regulation that dreams of emissions of protection and preservation of the environment (Suhendro, 2014) O' Reilly et al (2010) indicate that the optimal management of concrete technologies must be considered concerning the built works' useful life.…”

The manufacture and use of concrete are significant environmental pollutants due to its high CO2 emissions. Contrary to the current postulates of sustainable development and global pacts for the reduction of greenhouse gases, which is why during the last 20 Years have been developing new techniques and use of alternative materials, as raw material for the manufacture of concrete, with satisfactory results in terms of durability and resistance. The search was advanced in the Scopus database, using the search equation “green concretes”, filtering by title. Using bibliometric and network visualization tools, such as RStudio and VOSviewer, the information corresponding to 201 documents was processed and evaluated. The most significant findings indicate that China and India are leading the research on new technologies to use recyclable raw materials in the manufacture of green concrete, causing the global environmental impact in the construction sector to decrease. Additionally, it was found...
