【摘要】：以鉬尾礦、礦渣、熟料和石膏為原料制備膠凝材料,研究了鉬尾礦在膠凝材料中的摻量、減水劑摻量、養(yǎng)護工藝對膠砂試塊性能的影響,并通過XRD和SEM-EDS對水化產(chǎn)物進行了深入研究。結(jié)果表明,當(dāng)鉬尾礦在膠凝材料中摻量為20%、減水劑摻量為0.4%、采用60℃濕熱養(yǎng)護所制備的鉬尾礦膠砂試塊力學(xué)性能最好,28 d抗壓強度可以達到73.2 MPa。利用鉬尾礦制備的膠凝材料的水化產(chǎn)物以鈣礬石和C-S-H凝膠為主,二者的相互交織促進了膠砂試塊強度的增長。
[Abstract]:The cementitious material was prepared from molybdenum tailings, slag, clinker and gypsum. The effects of molybdenum tailings on the properties of cement sand were studied.The hydration products were studied by XRD and SEM-EDS.The results show that when the amount of molybdenum tailings in the cementing material is 20 and the amount of water reducer is 0.4, the mechanical properties of molybdenum tailings mortar prepared by hydrothermal curing at 60 鈩，
