Alkali
Cause of alkali-silica reaction. ASR is the most common form of alkali-aggregate reaction (AAR) in concrete; the other, much less common, form is alkali-carbonate reaction (ACR). ASR and ACR are therefore both subsets of AAR. ASR is caused by a reaction between the hydroxyl ions in the alkaline cement pore solution in the concrete and reactive

Abrasive Blasting
Respirable dust from silica sand and other abrasive materials pose a risk to the lungs. Where abrasive blasting is used to remove lead-based paint on the steel infrastructure of bridges, it can generate particles of lead that pose a risk to the nervous system. In addition to potential health hazards, abrasive blasting can pose safety risks as well.

Silica Sand in UAE
Silica (SiO2) is the name given to a group of minerals composed solely of silicon and oxygen. Found most commonly in the crystalline state, it also occurs in an amorphous form resulting from weathering or plankton fossilization. For industrial and manufacturing applications, deposits of silica-yielding products of at least 99% SiO2 are preferred.
