Concrete experiment maintenance equipment and control system thereof

Abstract

The invention provides concrete experiment maintenance equipment and a control system thereof. The concrete experiment maintenance equipment comprises a maintenance box, a computer, an automatic measurement and control system and a wireless temperature measurement device, wherein a cavity body and an equipment control case are arranged in the maintenance box, a concrete sample, a first temperature sensing device and a heating membrane are arranged in the cavity body, and the heating membrane is arranged on the side wall of the cavity body. The first temperature sensing device and the heating membrane are respectively and electrically connected with the equipment control case. A second temperature sensing device is arranged in site operation construction member concrete, and the wireless temperature measurement device is electrically connected with the second temperature sensing device. The computer sends a command according to real-time temperature measured in the site operation construction member concrete and through the automatic measurement and control system, and enables the heating membrane to synchronously adjust maintenance temperature in the maintenance box so as to achieve the aim that the concrete sample in the maintenance box and the site operation construction member concrete are maintained under the condition of same temperature, and thus reduce the gap in temperature process strength development of concrete sample strength and the site operation construction member concrete.

Description

technical field [0001] The invention belongs to experimental equipment, in particular to a concrete experimental maintenance equipment and a control system thereof. Background technique [0002] The current method of testing and evaluating concrete strength is to place the test pieces formed under laboratory conditions in a standard curing room or next to the components for curing until the specified age. However, there are obvious differences between the test pieces prepared in the laboratory and the actual conditions of the components in the project. The difference in temperature conditions is an important aspect of these differences, and the temperature difference has a very important impact on the strength development of concrete. Studies have shown that the hydration rate of Portland cement is doubled at 30°C compared to 20°C. [0003] In recent years, with the continuous increase of the cross-sectional size of the components, the increase of the cement strength grade ...

Problems solved by technology

This causes a large difference between the standard curing temperature in the laboratory and the temperature in the actual component, and thus leads to a larger gap between the strength of the specimen measured in the laboratory and the concrete strength in the actual structure.
