“…At 7 days after production, particle densities in SSD condition ranged from 1.591 to 1.834 g/cm 3 , and from 1.254 to 1.771 g/cm 3 in oven-dry condition. These values are significantly lower than those reported for pure fly-ash cold-bonded pellets (ranging from 1.650 to 2.120 g/cm 3 [14]) and close to those reported for agricultural wastes used as aggregates, such as coconut shells (ranging from 1.120 to 1.890 g/cm 3 [14,34,35]). Formulations at higher sawdust contents exhibited lower densities.…”

Due to urbanization, demand for concrete has been increasing up to 10 million cubic meter per year. Therefore, there is an urgent need to reduce the requirement for ingredients such as cement, sand, and aggregate. Cement serves as a binding material in concrete, which is being used in the construction industry since ancient times [1,2]. The admixtures are added in order to reduce the demand and supply gaps for cement, and the most common admixture is coal ash (CA) obtained from thermal power stations.

“…The concrete was compacted by vibration following IS:516-1959. All cast specimens were stored in laboratory conditions for 24 h before de-moulding and placed in a curing tank until testing was undertaken (Vasanthi et al 2020). The samples were removed from the curing operation and tested for mechanical properties and water absorption.…”

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.
