Concrete Wikipedia

Concrete is a composite material composed of fine and coarse aggregate bonded together with a fluid cement (cement paste) that hardens (cures) over time. In the past limebased cement binders were often used, such as lime putty, but sometimes with other hydraulic cements, such as a calcium aluminate cement or with Portland cement to form Portland cement concrete (for its visual resemblance to

PROPERTIES OF AGGREGATES FOR CONCRETE

Approximately 75% of the volume of concrete is occupied by aggregates, so quality of aggregates plays an important role in determining properties of concrete. Aggregates are chemically inert, solid bodies held together by the cement. Aggregates come in various shapes, sizes, and materials ranging from fine particles of sand to large, coarse rocks. Natural aggregates are formed by process of

Interestingly, iron sulfide in the body of the concrete usually doesn't decompose. Decomposition occurs near the surface where the mineral is exposed to air and water.

Petrography performed on the aggregate (ASTM C 295) can tell you how much of the aggregate

Iron Sulfides and Concrete

Pyrite and Pyrrhotite in Concrete Aggregate Iron sulfides are common in a variety of rock types and therefore may be present in aggregates used in concrete. Pyrite is the most stable iron sulfide mineral, but can still oxidize near the surface of concrete and stucco, leading to unsightly staining and pop-outs. In good-quality dense concrete, aggregate containing small amounts of pyrite can be
