“…The During the transport of raw materials to the concrete plant, embodied energy and CO 2 emissions were considered. The embodied energy of a road vehicle should be 2.4 MJ/t/km, and its CO 2 emissions should be 0.15 kg/t/km, according to the Bath Inventory of Carbon and Energy (ICE) (Sathiparan et al 2022). In this study, cement and aggregates were transported over 10 km.…”

The concept of sustainability in agricultural residue management has gained increasing traction around the world in recent years. After harvesting, large volumes of waste are generated that are often dumped into the environment, causing pollution. In addition to preventing environmental degradation, these wastes can also be used in the concrete industry to reduce mineral resource depletion. With this approach, sustainable development is possible. According to the results of this investigation, the effect of pigeon pea stalk ash (PPSA) as a partial replacement of cement in concrete, a series of experimental tests were performed. It has been found that the compressive strength increases for the mixes from 4 to 8% of cement replacement. In contrast, the strength decreases when the percentage replacement of pigeon pea stalk ash with cement exceeds 8%. Based on the experimental results, concrete infused with 8% pigeon pea stalk ash increased its compressive strength by 6.96%. The compressive strength decreased with a further increase in PPSA content. Although the split tensile strength value of PPSA8 concrete was same value compared to the control concrete, even an 8% PPSA concrete has higher strength than other replacement levels. Concrete with 8% PPSA content was observed to have a higher flexural strength than control concrete. PPSA concrete was prepared with pigeon pea stalk waste up to 8% substitution of cement. PPSA concrete has reduced permeability and higher resistance to acid attack. All the strength and durability test results revealed that PPSA concrete type was superior to the control concrete in terms of mechanical qualities and durability characteristics. The present work discusses concrete's improved economic and environmental aspects with incorporated pigeon pea stalk ash. Hence, this study points toward the highest potential use of more concerned about agricultural wastes like pigeon pea stalk ash in green concrete.

“…Results show that treated cocopeat improved the compressive strength and bonding characteristic of concrete. The strength and durability properties of cement mortar including cocopeat as a substitute for river sand were evaluated by Sathiparan et al (2022). The findings demonstrated that adding up to 4% of cocopeat content to cement-sand mortar enhances its physical and mechanical characteristics without negatively affecting crucial durability factors.…”

The production of agricultural, industrial, and demolition trash increases along with global population growth and industrial expansion. They endanger the environment when they are not properly recycled, repurposed, or disposed of. Cocopeat is one such agricultural waste. The use of cocopeat in binder cement is urged to support sustainable construction methods. Because it is seen as trash and discarded in landfills. Cocopeat is an environmentally friendly by-product which can be got during the coconut fibre extraction process. The current study investigates the strength properties of masonry built with binding mortar that incorporates cocopeat as opposed to traditional cement-sand mortar. The mortar prepared with four different integrations of cocopeat as sand replacement of 0, 4, 6 and 8% by weight was used for masonry. Fresh properties of cocopeat binding mortar and their effect on the mechanical characteristics of masonry were investigated. The test results revealed that the mechanical characteristics of masonry were enhanced with increased cocopeat content in the mortar.
