Concrete has become a major construction material all around the world with over ten billion tons consumed annually. One of the major issues to be kept monitored during manufacture of concrete is its initial setting time; that is to say, the time needed for the initiation of fresh concrete's...

In 2012, Kaspi made a striking move by discontinuing its credit card business within 48 hours of receiving negative Net Promoter Score (NPS) feedback. This decision was particularly noteworthy as the credit card division represented one-third of the company's revenues at the time. A particularly...

3D concrete printing requires the precise control of fresh concrete properties such as flowability, extrudability, and resistance to segregation during printing process. The initial setting time of the concrete also needs to be controlled as it needs to adhere to the next layer and then harden ...
Setting time well corresponded to the period of maximum Ca(OH) 2 saturation ratio in liquid phase which coincided also with the period of vivid hydration of alite. Soft burning of clinker so as to remain a little amount (0.5% level) of free lime was effective for shortening the setting ...
