Abstract To study the effect of marine shell powder (SP) on mechanical properties cement solidified coastal clay (CSC), unconfined compressive strength test, freeze-thaw cycle test and Scanning Electron Microscope were conducted stabilized soil. The results show that SP could improve CSC to some extent. When content was 15%, highest. Moreover, under condition cycle, can enhance compactness ceme...

The adverse consequences of producing ordinary Portland cement (OPC) on the environment have introduced production as fourth largest source anthropogenic carbon emissions after petroleum, coal, and natural gas. Managing reducing environmental concerns regarding impacts environment, namely depletion non-renewable fuel resources, consumption raw materials, releasing huge amounts CO2 into atmosphe...

Phragmatopoma Californica builds a tubular dwelling by gluing bits of sand and seashell together underwater with a proteinaceous adhesive. In the lab, the animals will build with 0.5 mm glass beads. Two spots of glue with a consistent volume of about 100 pL each are deposited on the glass beads before placement on the end of the tube. The animals wriggled the particles for 20-30 s before lettin...

The concept of utilizing various types wastes, such as agricultural dumps and marine by-products, a partial replacement cement has gained great interest to develop eco-friendly economical mortars for sustainable construction. This study aims evaluate the feasibility using palm oil fuel ash (POFA), an agro-industrial waste by-product from mills seashell powder (SSP) derived seashells, material i...

As a typical biomineral, hydroxyapatite (HAp) is widely applied in bone implants and other related fields. However, the inherent nature of HAp can potentially be altered through restricting its fabrication conditions. Here, HAp fabricated by a hydrothermal treatment of pieces of natural seashell is demonstrated to have the capability of fluorescence quenching. To the best of the author's knowle...

Nacre has recently attracted the attention of the research community. This biocomposite has exceptional strength and toughness with respect the materials it is made of. The design of nano and micro composite inspired from nacre requires a deep understanding of nacre microstructure and mechanical properties. In this work, the elastic properties of aragonite tablets in nacre were determined using...
