Quality control in Construction – it all starts with concrete

The construction quality control system. Looking in more detail at the way the concrete quality control system works, it can be understood that the discrepancy of concretes makes it possible to minimise the consumption of cement, and ultimately allows the production of concrete to run more economically (Troxell, Davis Kelly, 1965).
