In the present era of technically feasible and environmentally compatible low-cost material substitution with the basic ingredients of conventional concrete mix, the infusion of eggshell powder in its raw as well as incinerated forms was tried with the cement mantle. Experimentations carried out to endorse the compressive strength, split tensile strength, flexural strength, workability and durability aspects revealed that it had the edge over the properties standardized for the conventional concrete mix at a specific mix strength of 20 MPa. The experimental results for variations in the treatments of eggshell powder and incinerated eggshell powder corresponding to the responses on the evaluation parameters were compared with the conventional concrete mix by means of regression analysis and modelling. The regression model at more than 95% correlation level of the experimental data fortified the relative supremacy of eggshell powder and incinerated eggshell powder-infused concrete mixes over the conventional concrete mix in terms of workability, strength, and durability. Based on the statistical regression point of inflexion and the point of tolerance, it was clearly established that 20% optimal proportional addition of eggshell powder or 30% addition of incinerated eggshell powder could result in a superlative performance compared to the conventional concrete mix. This final outcome of the optimal combinations of eggshell powder and incinerated eggshell powder incorporated concrete (EPIC) was also test verified by SEM and EDAX analyses.

One of the main sources of dangerous chemicals that are dumped untreated into land and water bodies and have a negative influence on the ecosystem are industrial effluents. Seaweeds are currently used for treating industrial effluent effectively. The technology is at a maturing stage. This paper reviews the characterization and cultivation of seaweeds for wastewater treatment. In this present study, different extracts of four seaweeds such as Gracilaria edulis, Sargassum wightii, Turbinaria ornata, and Kappaphycus alvarezii, from the Mandapam coastal regions were analyzed. The seaweeds are used to treat the leather industry effluents collected from EKM leather processing company, Erode, Tamil Nadu, India. Among all, extracts of Gracilaria edulis survived at different concentrations of TDS: 15,000, 25000, and 35000 mg/l. Out of these different ranges, TDS of about 25000 mg/l seaweed named Gracilaria edulis reduced more amounts of chemicals present in the effluent like TDS (93.90%), phosphates (72.71%), nitrate (75.08%), nitrite (76.92%), and turbidity (99.01%) content. Additionally, we produce the quality and strength of agar gel from the cultivation of Gracilaria edulis by the Nikansui method. Finally, we got the extraction procedure to obtain a higher yield of about 10.26% and a maximum gel strength of 92.06 g·cm−2 while maintaining the melting point at 78°C.

Abstract. In order to investigate the recycling possibilities of coarse oyster shell aggregate, the chemical compound of oyster shell and reactivity of oyster shell with cement paste was examined. Specifically, the mechanical characteristics of fresh concrete and hardened concrete were quantified in terms of oyster shell substitution rates. Test results indicate that there is no interaction between oyster shell and cement paste and that concrete's workability decreases as the substitution rate for oyster shell increases. The decrease was about 20% at a substitution rate of 30%.

Abstract: Innate fibres, these days have become the topic of argument in the research field between different scientists to inculcate it in the formation of lightweight concrete mixture. This is due to a variety of rewards connected with natural fibres like recyclable, economical, availability in large quantity and its bio-degradability. Plenty of projects have been carried out in the production of natural fibre reinforced lightweight concrete. In this project, we would like to take the naturally existing fibre named sisal fibre and banana fibre as partial replacement material. The adding of natural fibre to the lightweight concrete will enhance the diverse strength parameters like flexural strength, compressive strength, and increase the ductile behaviour. In the current work, it is intended to explore the mechanical properties of lightweight concrete with substitution of sisal fibre and banana fibre for cement in different percentages. The compressive strength, flexural strength, deflection of the beam is calculated with the reflection of M30 concrete specimens. Totally 45 number of 500 x 100 x 100mm flexural member, 45 numbers of cubes and 45 numbers of cylinders are cast and tested. It is suggested that up to 1.5% substitution of sisal fibres and banana fibre with cement provide at M30 grade of concrete giveing the most beneficial increases of strength values. The assessment outcome indicated that the sisal fibres and banana fibre were efficient in improving the performance of lightweight concrete
