Hydraulic concrete variable-temperature curing method and device

Abstract

The invention relates to the technical field of hydraulic concrete, and particularly relates to a hydraulic concrete variable-temperature curing method and device. The hydraulic concrete variable-temperature curing method is used for curing hydraulic concrete in a curing box in a variable-temperature environment, and a temperature sensor, a humidity sensor and a water spray device are installed in the curing box. The hydraulic concrete variable-temperature curing method comprises the steps of receiving real-time temperature, which is sent by the temperature sensor, in the curing box, adjusting the temperature in the curing box on the basis of the real-time temperature according to set temperature corresponding to each preset moment, receiving real-time humidity, which is sent by the humidity sensor, in the curing box at the same time, and controlling the water spray device to adjust the humidity in the curing box according to the real-time humidity, so that the temperature and the humidity in the curing box are adjusted so as to simulate an actual environment, the hydraulic concrete is cured in the variable-temperature environment, and the performance index of the hydraulic concrete is close to the practical application environment.

Description

technical field [0001] The invention relates to the technical field of hydraulic concrete, in particular to a method and device for hydraulic concrete curing at variable temperatures. Background technique [0002] The existing hydraulic concrete test regulations have clear regulations (SL352-2006): "The temperature of the standard curing room should be controlled at 20°C ± 5°C, and the relative humidity should be above 95%. When there is no standard curing room, the specimens can be placed in the Curing in saturated lime water at 20℃±3℃”. It can be seen that the existing hydraulic concrete specimen curing devices and methods are based on constant temperature and humidity curing at a temperature of 20°C, and the performance of concrete specimens grown in such an environment is used as an index for evaluating concrete performance. Engineering construction provides reference. The engineering practice shows that the performance of concrete grown under such conditions cannot re...

Problems solved by technology

The engineering practice shows that the performance of concrete grown under such conditions cannot reflect the actual engineering concrete situation. The environment in which the actual engineering concrete is located is a constantly changing environment of temperature and humidity. Different temperature changes, even short-term cold waves and other sudden temperature drops, the performance of concrete grown under such environmental conditions will have a large gap with the performance of concrete grown under constant temperature and humidity conditions
