The new innovative technology has been developed by Sensocrete Inc. of Quebec, Canada. It is successfully applied in Canada. It uses electromagnetic sensors to control ready mix concrete quality, namely slump (± 10 mm), segregation, volume (0.1 – 0.2 m3) and temperature.

Conventionally, concrete mix is overdesigned to make up for loss of strength during transit. Water is added to RMC to make up for loss of slump during transit. Both the actions are done arbitrarily resulting in more cement quantity and higher cost and loss of strength due to excess water.  

The Sensocrete Concrete Optimizer carries out continuous measurement, recording and  analysis of slump data during transit, which enables addition of water and chemical admixtures within mix design parameters. Thus arbitrariness eliminated and concrete is delivered with the required slump.

The continuous measurement, recording and  analysis of slump data during transit informs Quality Assurance personnel about non-uniformity due to segregation. In the transit mixer, segregation suggests improper mixing of concrete or the maintenance of mixer drum. It also indicates time when concrete gets completely mixed and to be poured.

The application of Sensocrete Concrete Optimizer enables exact quantity of concrete delivered at the site, due to accurate measurement of  volume (0.1 – 0.2 m3). The continuous measurement of temperature keeps track of setting process. The set retarder can be added by Quality Assurance personnel, when increase in temperature is observed.  

The delivery of concrete with required volume and slump saves back charges for incorrect slump, decreases mistakes that lead to liability claims, provides information on trouble shooting and improves entire delivery process.  Using this process, concrete producers could reduce cost, cutting the “margin of safety” in water and cement and still maintain  water/cement ratio for required strength.
