PERI is coming up with its digital sensor range to cut concrete testing times for contractors on site, starting from this week. PERI said the hand-held device can take a series of water to cement ratio measurements in just two minutes.
The time frames for measurements of cement mixtures can be compared so quickly, said the company, compared to traditional methods. While approximate testing with traditional methods for a single test takes up to eight hours, the new testing methods are far better and accurate.
SONO WZ sensor is one of the first in the construction industry by formwork specialists. This equipment is used to measure the water to cement ratio in fresh concrete mixes. It also provides enhanced quality assurance before placement.
The sensor by PERI has undergone a successful trial with civil engineering subcontractor Joseph Gallagher Ltd on Tideway’s Chelsea Embankment site. It is looking to launch another three sensors over the next year, each one offering different benefits to the construction process.
