Abstract
A sensing device includes a concave side adapted to conform to a curvature of an outer side of a standard concrete test cylinder, a temperature sensor, and a humidity sensor. In one embodiment, the sensing device includes a capillary needle disposed on the concave side. The capillary needle comprises a humidity sensor. The sensing device is attached to the side of a concrete test cylinder, temperature and humidity measurements are obtained by the sensing device, and a prediction of maturity and strength of the concrete is generated based on the temperature and humidity measurements.
Claims8
A system comprising:
- a cylinder adapted to hold a mixture, the cylinder having a side wall having a convex outer surface and a hole in the side wall;
- a ring that defines 360 degrees and encircles an outer side of the cylinder;
- and
- a sensing device disposed on the outer side of the cylinder and attached to the ring, the sensing device comprising a concave surface having a first shape that corresponds to a second shape of the convex outer surface of the cylinder, the sensing device further comprising:
