    What Is Silica Sand & How Is It Different From Regular

    Silica sand, also known as quartz sand, white sand, or industrial sand, is made up of two main elements: silica and oxygen. Specifically, silica sand is made up of silicon dioxide (SiO2). The most common form of SiO2 is quartz a chemically inert and relatively hard mineral. SiO2 grades at a 7 out of 10 on Mohs hardness scale, making it ideal for use as filtration media and abrasive

    Alkali–silica reaction Wikipedia

    The alkali–silica reaction (ASR), more commonly known as "concrete cancer", is a deleterious swelling reaction that occurs over time in concrete between the highly alkaline cement paste and the reactive amorphous (i.e., non-crystalline) silica found in many common aggregates, given sufficient moisture.. This deleterious chemical reaction causes the expansion of the altered aggregate by the
