How to Process Silica Sand? JXSC Machine
Silica sand, also known as quartz sand, is mainly composed of silica( SiO2), which is the main raw material for making glassSilica sand has ordinary silica sand, refined silica sand and high purity silica sand The content of silicaXray fluorescence analysis (XRF) is the method of choice for the material analysis of silica sand of all kinds, because you can quantify the main component SiO2 (mostly over 98 %) next to the Fe2O3 traces as well as the unwanted oxides of feldspar and clays (Na2O, MgO, Al2O3, K2O, CaO) in one measurement stepsilica sand method of working
Silica Sand an overview | ScienceDirect Topics
To make calcium silicate bricks, silica sand is mixed with high calcium lime at a sand–lime ratio of 10 or 20 The mix is then compressed into moulds and “autoclaved” at about 170°C (340°F) for several hours Some gel, similar to the calcium silicate hydrate gel of the type that is formed by cement, is formed, and this bonds the sand particles togetherAnother properties of silica sand we need to know are the specific gravity, moisture content, fineness modulus Specific gravity can be find out by pycnometer bottle method by taking 200gm of silica sand Table 25 Physical properties of silica sand Gradation Fall in Zone I Moisture content 14% Fine modulus 256 Silt content 078% Table 26 Moresilica sand method of working
