Abstract：The effect of immersion duration,immersion temperature and immersion reagent type on the soundness of typical source rock used for manufactured aggregate was studied by temperature rise control.Furthermore,a rapid evaluation method for assessing the soundness of source rocks for manufactured aggregates was proposed based on temperature rise control and reagent type.The results show that the mass loss of source rock soundness increases significantly with the increase of the immersion duration,the immersion temperature,and the MgSO4 solution as the immersion reagent due to the increase of solution crystal volume or the diffusion depth.Compared to the test results obtained by standard method,when the immersion duration is 13.5 h,the immersion temperature ranges from 60℃to 80℃,or the immersion reagent is magnesium sulfate solution,the mass loss ratio of source rock soundness increases by 1.1 to 1.4 times.
