Concrete wet-hot curing system

Abstract

The invention belongs to the technical field of rapid concrete curing, and particularly relates to a concrete wet-hot curing system. The concrete wet-hot curing system comprises a reaction kettle, a steam inlet, an exhaust port, a vacuum pumping device, a water outlet, microwave heaters and inner rails, wherein the reaction kettle is horizontally arranged, the steam inlet, the exhaust port and the water outlet are formed in the reaction kettle, the vacuum pumping device is arranged on the reaction kettle, and the inner rails are arranged in the reaction kettle, and allow a loading trolley to enter and go out. An end cover is hinged to one end of the reaction kettle, a supporting base is arranged at the bottom of the end cover, and outer rails which align at the inner rails are further arranged on the supporting base. Connecting rails are arranged inside the end cover and connected with the end cover in a sliding mode, and the rotating plane of the connecting rails coincides with the inner rails. Springs which push the outer rails to slide towards the end cover and are connected with the connecting rails are arranged on the outer rails. By the adoption of the technical scheme, the concrete wet-hot curing system is faster to cure, saves energy and is adjustable in pressure and temperature.

Description

technical field [0001] The invention belongs to the technical field of rapid concrete maintenance, and in particular relates to a damp heat maintenance system for concrete. Background technique [0002] As the largest material in the construction field, concrete is widely used. In the field of ready-made concrete, the evaluation of concrete quality is mainly based on the characterization of the compressive strength of 28d specimens. Due to the long evaluation period of the results, when the quality of raw materials fluctuates or the environment changes When it is large, it often occurs that a certain batch or inspection batch of concrete is not strong enough for 28 days, and it has been poured on a large scale when it is found. loss and reputational crisis. In order to quickly predict the 28-day compressive strength of concrete, on the premise of not artificially "dividing" the components of concrete and maintaining the integrity of the concrete test block, according to the...
