How long it takes to construct a building depends in large part on when the concrete of each floor is strong enough to take on loads. Purdue University engineers have developed sensors that could safely speed up a construction timeline by determining concrete strength directly onsite in real time.
Typically, concrete mix designs require testing before implementation in a construction project. Once those mixes have been vetted for use, the mix design cannot be altered without additional offsite testing.
