Concrete Sensors is putting its technology
into the mix, literally. The company offers
two types of sensors - CS100
and CS200 - depending on
the depth of the pour that are
embedded in the concrete.
The sensors are zip-tied to rebar
and as the mixture sets, the sensors
measure the internal temperature and
humidity, which are two factors critical to
the curing and drying process that concrete
must go through before a building can
be completed. The sensors transmit data
using Bluetooth and can be read from 10

walk around with a smartphone or tablet to
check the concrete's progress.
"You should be collecting data on all
the concrete you're pouring, but existing
methods of testing like making cylinders or
drilling holes to take humidity readings are
time-consuming and inconsistent," Dowdall
says. "Because of this, construction firms
often schedule more time, or allocate more
costs, than actually needed."
Concrete Sensors starts taking data the
day the concrete is poured, which improves
scheduling and can save a lot of money.
"We like to say that we can help general
contractors save a day per pour of concrete,"
Dowdall says. "Most commercial projects
cost $10,000 to $20,000 per day to operate
the job and that can add up."

Mirpuri says contractors are always trying
to increase productivity, hence looking
for tools that will make their jobs easier.
"We strive to provide real-time data to our
customers that's actionable and reliable," he
adds. "Concrete Sensors shows its value by
understanding and sharing that goal."

lab that allows for the most accurate testing
