Concrete degradation – Wikipedia

Concrete degradation may have various causes.Concrete can be damaged by fire, aggregate expansion, sea water effects, bacterial corrosion, calcium leaching, physical damage and chemical damage (from carbonatation, chlorides, sulfates and non-distilled water).This process adversely affects concrete exposed to these damaging stimuli.

The role of calcium carbonate in cement hydration

However carbonate AFm phases are thermodynamically more stable than hydroxy or sulfate phases and it is not surprising that hydroxide and sulfate anions are released from AFm even at the low carbonate activities conditioned by the presence of added calcite (or other calcium carbonate form).

Effects of ultrafine fly ash on the properties of high

The replacement ratio of low-calcium fly ash incorporated in high-strength concrete with water-to-binder ratio of 0.24 can be up to 45 %, meanwhile reaching the equivalent compressive strength of plain concrete, as was the case in Ref. . But 80 % of the fly ash remained unreacted at the age of 90 days and served as micro-aggregate.
