Binder effect on seashell structure Free

Self-protection or known as defensive covering can be alluded to something that can secure body, building, or vehicles from harm or assault. As the evolution going on, the material utilized as a part of plate armour continue changing, from steel, Kevlar, ceramic and the materials that can give better impact and benefit to the user. A study has been led to distinguish either seashell can be one of the fundamental source to produce protective material due to the properties of seashell that consist of calcium chloride. Seashell is crushed and chipped using variable speed rotor mill and is compressed into specimen shape followed the ASTM C1211-13. Three different samples is tested made from seashells that mix with three different binder i.e. water, kaolin and polyethylene glycol (PEG) each. The specimens then were sintered at elevated controlled temperature 400°C before run for three point bending test to determine their mechanical properties results. Result shows that specimen with water gives highest value for Young’s modulus and ultimate strength compared to sample with binder of kaolin and PEG. This proved that seashell powder remain intact even at higher temperature.
