Pressing-in device for recycled aggregate regulation and control reagent

The invention discloses a pressing-in device for a recycled aggregate regulation and control reagent. The pressing-in device comprises a vacuum tank (2), a beaker (6) and a vacuum pump (4), wherein the vacuum tank (2) is arranged in an ultrasonic vibration instrument (1) and is provided with a sealing cover (3), and the beaker (6)communicates with the interior of the vacuum tank (2) through a glass tube (8). According to the pressing-in device for the recycled aggregate regulation and control reagent, the regulation and control reagent can be pressed into recycled aggregate pores, meanwhile, an environment required by a hydrolysis reaction of tetraethoxysilane and conditions required for immersing the reagent into the internal pores are provided, and the influence of reaction parameters onthe reinforcement effect of recycled aggregate is conveniently studied; and therefore, the performance of the recycled aggregate is improved. 本发明公开一种再生骨料调控试剂压入装置，包括置于超声波震动仪(1)内的带密封盖(3)的真空罐(2)、通过玻璃管(8)与所述真空罐(2)内部相通的烧杯(6)和通过真空
