The big difference first the opc and fly ash were dry mixed in a clean dry pan between concrete, mortar or grout is their plasticity or for about 3 minutes until they were blended uniformly and fluidity in the initial stage. The grout sets as the water evaporates out of the mixture. Designing concrete mixtures there are three phases in the development of a concrete mixture:
Concrete Mix Design
Initial setting time = 10 hours (more than 3 hours & less than 12 hours as per mort&h 5th rev. Volume of cement = (weight of cement / specific gravity of cement) x (1/100) = (383.2/3.15) x (1/1000) = 0.122 m3. Concrete producers must “retrain their eyes” for this very fluid mixture as it turns corners and fills forms. Grouting can be used for fixing cracks in concrete which can turn into major problems in the future.
