Influence of Mixing Time on Workability and Strength Properties of Concrete in Different Consistency
A series of experiment based on different mixing time were carried out to investigate the effect of mixing time on slump, modified VC value and strength properties of concrete in different consistency. The flexural strength, compressive strength on the conditions of highly stiff s, stiff and plastic system was studied. The optimized mixing time was determined and its reason was analyzed. The examination result show that the highly stiff concrete have the best performance when the mixing time is at about 120s, the stiff system is at 60s, the plastic system is at 30s.
