“…The construction industries are increasing every year, there is a problem of shortage of material. So, the researcher's interest in search of alternate building materials [5,6]. Recently the construction material production has been using natural aggregates, now a days research works are proposed to use natural aggregate as by product in concrete [1].…”

“…For these environmental issues, cement industries somewhere practising several by product materials such as industrial waste, blast furnace slag, agricultural waste, mining waste etc. Increased volume fractions of supplementary materials such as fly ash, slag and volcanic dust produce more environmentally sustainable concrete and a mixture with high workability, extreme strength and durability [9,10]. These by product act as a mineral admixture that reduce the environmental impact of cement production [8,11].…”

This research mainly concentrates on eco-friendly construction material. Production of cement and concrete industries release huge amount of carbon dioxide (CO2) and greenhouse gases which affect the environment and also there is a demand in construction material by man-made or nature. The construction sector finds an economic and eco-friendly cement replacement material to achieve the demand for green concrete that improve the energy conservation and better energy saving material. In marine Bio-refinery waste produce huge quantity of calcium carbonate, whose disposal is cause of major concern. Pre-eminent solution for this problem is utilizing the marine shell waste in cement and concrete. It revises the manufacturing process to reduce the raw material usage in production and adoptable material for global warming. Therefore, the researchers focus on marine waste sea shells as the replacement material in construction industry to save the energy and also give sustainable green material. As per the previous studies by the researchers to determine the chemical composition, specific gravity, water absorption, particle size distribution of seashells and also compressive, flexural and tensile strength of concrete. It shows the seashell is filler material that slightly increases the strength when compared to the conventional materials and therefore the sea shells are suitable for the construction field to manufacture the cement and concrete with eco-friendly manner.

“…Rahul Rollakanti reported that crushed seashell was replaced by cement at 10%, 20%, and 30%, respectively. The results showed that compressive strength was approximately the same at 10% and gradually dropped as the percentage of seashells was raised [38]. According to Lertwattanaruk et al [39], using seashell at weights of 5%, 10%, 15%, and 20% as partially replace cement decreases the amount of water used and increases the time that took for the mortar to firm up.…”

The concept of utilizing various types of wastes, such as agricultural dumps and marine by-products, as a partial replacement of cement has gained a great interest to develop eco-friendly and economical mortars for sustainable construction. This study aims to evaluate the feasibility of using palm oil fuel ash (POFA), an agro-industrial waste by-product from palm oil mills and seashell powder (SSP) derived from seashells, a marine waste material partial replacement of cement in mortars. The water to binder (w/b) ratio of 0.49 and the sand to binder (s/b) ratio of 2.54 with 0% to 30% of ordinary portland cement (OPC) by weight was replaced with POFA and SSP, and the resulting mortar samples were tested for mechanical properties and durability in this study. The compressive strength, flexural strength, water absorption, and flow table tests were performed in this study for different percentages of POFA and SSP after 7, 28, and 130 days. The results showed that the 30% POFA incorporated mortars achieved the highest compressive strength (35.12N/mm2), flexural strength (4.06N/mm2), high density with less water absorption (4.79%) after 130 days of curing and the high strength mortar with less water flow (22.2cm) during casting. Also, it found that the 25% POFA and 5% SSP incorporated mortars attained acceptable results as supplementary cementing material. This study suggests that the POFA and SSP incorporated mortars could be used in concrete for sustainable development of construction through the efficient valorization of waste materials.
