Process Technology Silica Sand into Microsilica and Nanosilica for Construction Material

Abstract

Nanotechnology has experienced rapid growth, it can be seen the emergence of products and high interest researchers associated with nanotechnology. The implication process natural resources management is no longer limited to generating value addition, but were able to perform value creation. One potential source is the natural silica sand. Silica sand reserves in Indonesia, among others are, South Kalimantan, West Java, East Java and Papua. Utilization of silica sand has been used as a filler only on the construction materials at a price of 20 - 50 IDR/kg, while microsilica: 12,000 – 15,000 IDR/kg and nanosilica: 100,000-150,000 IDR/kg. This study develops the potential of silica sand in Indonesia through testing, XRF, XRD, SEM and PSA. Then further process by nanosilica’s equipment in Indonesia, resulting microsilica and nanosilica Indonesia. The end result made ​​comparisons with microsilica and commercial nanosilica. The results showed that the Planetary Ball Mill (PBM), High Energy Milling (HEM) can be used to generate microsilica. Polishing Liquid Milling Technology (PLMT) can be used to make nanosilica of Indonesia's natural resources, which is equivalent to nanosilica have traded commercial.
