检验重矿渣的稳定性,需同时进行蒸煮试验(或蒸压试验)和饱和硫酸钠溶液浸泡试验。试验时,取粒径40～50毫米的重矿渣50颗,先刷洗干净,然后烘干(105士5℃)至恒重。取其中25颗进行蒸煮或蒸压试验,其余25颗进行饱和硫酸钠溶液浸泡试验。两组重矿渣试样应分别称重并进行仔细 Inspection of the stability of heavy slag requires simultaneous cooking test (or autoclave test) and saturated sodium sulphate soak test. During the test, 50 heavy slag particles with a particle size of 40-50 mm were used. They were first brushed and then dried (105±5°C) to a constant weight. Twenty-five of them were subjected to steaming or autoclaving tests, and the remaining 25 were saturated sodium sulphate soaking tests. Two groups of heavy slag samples should be weighed and carefully
