Abstract

The invention discloses an automatic concrete setting time measuring device capable of simulating a field environment and a using method thereof. The device comprises a box body, a sample cylinder, apenetration resistance measurement module, an air blowing module, a sunlight simulation module, a temperature and humidity sensor, a heater, a refrigerating machine, a dehumidifier, a humidifier and asmall microcomputer, wherein the small microcomputer is connected with the temperature and humidity sensor to monitor and record the temperature and humidity in the box body in real time; the small microcomputer controls the operation of the air blowing module, the sunlight simulation module, the heater, the refrigerator, the dehumidifier and the humidifier; and the small microcomputer is connected with a penetration resistance measurement module to obtain measurement data fed back by the penetration resistance measurement module and analyze and process the measurement data to obtain a penetration resistance value and a penetration resistance-time curve, so that the setting time of the concrete is obtained. The device can simulate the construction site environment in the box body, the initial and final setting time of concrete in the construction site can be accurately judged in a laboratory, and the labor intensity of personnel is low.

Description

technical field [0001] The invention relates to the technical field of automatic measurement of concrete setting time for simulating field environment, in particular to an automatic measurement device for concrete setting time of simulating field environment and a method for using the same. Background technique [0002] As the main index reflecting the setting performance of concrete, setting time has important reference value for the preparation, transportation and application of concrete mixture. According to GB / T 50080-2016 "Test Methods for Performance of Ordinary Concrete Mixtures", the setting time of concrete is determined by the penetration resistance method, and the penetration resistance-time curve fitting of the mortar sieved out of the concrete mixture is measured and drawn. income. This standard defines the corresponding time when the penetration resistance is 3.5MPa and 28.0MPa respectively as the initial setting time and final setting time of concrete. [00...
