Understanding the concept of setting time of cement is important while handling concrete like transporting, placing, and compaction. Setting of cement is relevant to concepts like hydration process andhardening. In normal circumstances, when you are usingconcrete, you want it in a workable or flow-...
The invention discloses a method for prolonging the setting time of cement. Phosphogypsum powder accounting for 8-12% of the total weight of clinker is added during grinding of cement in order to control the weight percentage of SO3. The method allows the content of SO3 in cement to be ...
