This research elucidates the idea of eco-friendly concrete and highlights benefits attainable from its effective practice towards sustainable construction materials. The design mix employed a water/cement ratio 0.5, 1:2:4, varying percentages 2.5 mm seashells, 4.75 river sand as fine aggregates, granite 20 coarse aggregates. Laboratory tests showed that true slump was achieved for all mixes dec...

Asbestos has been banned in many countries as a result of its negative effects on the environment and human health. As result, human-friendly friction material is required to replace asbestos brake pads. Hence, powder metallurgy technique was undertaken develop from locally sourced asbestos-free materials. Seashell used base elements with other additives. The filler considered had particulate s...

Pervious concrete is a green alternative to conventional pavements with minimal fine aggregate and a high void content. Pervious concrete allows water to infiltrate through the pavement, thereby reducing the runoff and the requirement for stormwater management systems. Seashell By-Products (SBP) are produced in an important quantity in France and are considered as waste. This work investigated ...

Objective: This in-vitro study evaluated the remineralizing effect of nano-pearl and nano-seashell incorporated into fluoride-based pits-and-fissures sealants by assessing enamel surface microhardness elemental analysis. Materials Methods: 75 extracted third molars were randomly allocated to one following 5 groups fluoride containing sealant: 10% nano-pearl; 15% nano-seashell; or plain sealant....

We present Relaxation Island, one of several Mood Devices we have developed with our partners as part of the EMMA (Engaging Media for Mental Health Applications) project. Mood Devices are interactive digital media and environments designed to alter the inter-actor’s psychological state. Relaxation Island was designed to support established relaxation techniques, as part of interventions to assi...

Increasing of human population in the world has result rapid construction sector that demands high amount concrete. One raw materials concrete is cement and mass production it highly energy intensive brings harm to environment. To reduce usage cement, many researchers had proposed incorporation natural material as a binder which results significant outcome increasing their mechanical properties...

Porous asphalt pavement is mainly used for parking lots which able to let water drain through the surface into a stone recharge bed and infiltrate soils under pavement. This study investigate performance of seashell in porous determine image analysis. The this cockle shell. strength was determined Aggregate Impact Value Test (AIV) Crushing (ACV). grade bitumen 60/70. volumetric properties Marsh...

The seashell-shaped wind turbine (spiral SWT), a brand-new form of the horizontal axis turbine, is intended for metropolitan use. SWTs have additional advantage being installed anywhere without considering their surroundings, as they do not need to be located facing direction. present work introduces various designs rotor seashell achieve greatest performance. Two types spiral profiles (logarit...
