Detailed calcium silicon ratio and concrete

calcium silicon than the larger, more vulnerable to sulfate attack concrete and alkali-aggregate reaction. Besides ettringite recrystallization will decompose, resulting in poor stability. One of these is generally mixed with volcanic ash admixture purpose is to improve the material and silica fume silica, calcium granules than concrete, so that the mechanical properties and durability of concrete to achieve better. Theoretically hydrated calcium silicate silicon ratio is between 1.7 to 2.3 at. Over this range, the concrete will be a problem.
