Why is active silica the harmful component of aggregate?
Aggregate water project is sand (gravel), egg stone, referred to as gravel, stone, stone and other materials. A particle larger than 5mm is called coarse aggregate, that is to say, a stone that is less than 5mm in diameter and is called a fine aggregate, also known as sand. Sand and gravel are the main building materials for concrete and pile stones in water conservancy projects.
Reactive silica is a harmful component, mainly because the source material in the aggregate contains too much alkaline material, while reactive silica can react with the alkaline material, resulting in the destruction of aggregate components.
Silica widely exists in nature and forms rocks with other minerals. Naturally occurring silica, also called silica, is a hard, refractory solid.Quartz is also the main component of silica, transparent quartz crystal, that is, we often say crystal.
