| 摘要 |
A vessel (1) is placed into the concrete, immediately after concreting the construction element, in which there is a capillary (5) filled with a volatile liquid (4), for example, isopropanol, then the speed of the vaporization of the volatile liquid (4) in the capillary (5) is monitored according to the maturity of the concrete which is proportional to the strength of the concrete. The equipment for applying this method consists of a vessel (1) in which there is a capillary (5) filled with a volatile liquid (4), for example, isopropanol, equipped with a scale (8) mounted on the removable cap (7) of the vessel (1).<IMAGE>
