摘要/Abstract

摘要： 为了验证云南省生产的黄磷渣作为辅助胶凝材料的可行性,本文对比研究了矿渣和黄磷渣的粉磨性能和胶凝性能,并对它们作为辅助胶凝材料的性能进行了分析比较。结果表明,矿渣和黄磷渣具有相似的化学成分和矿物相,经历相同粉磨时间后,矿渣和黄磷渣的粒径分布、比表面积和微观形貌相似。矿渣和黄磷渣比表面积的增大促进了水泥的水化,提高了矿渣和黄磷渣自身活性,且在相似比表面积下,矿渣的活性高于黄磷渣。矿渣和黄磷渣的加入对水泥胶砂的后期强度有很大贡献,水泥胶砂的后期强度随着矿渣和黄磷渣比表面积的增大逐渐增大。当矿渣和黄磷渣比表面积为340和521 m²/kg时,单掺30%(质量分数)矿渣和黄磷渣的水泥胶砂28 d抗压强度分别为46.5和47.3 MPa,均大于纯水泥胶砂。当矿渣和黄磷渣比表面积分别为775和802 m²/kg时,水泥胶砂28 d抗压强度分别为58.7和50.9 MPa。总的来说,本研究中黄磷渣是一种可利用的具有较高活性的辅助胶凝材料,但应注意黄磷渣对水泥基材料的缓凝作用。

Abstract: In order to verify the feasibility of yellow phosphorus slag produced in Yunnan Province as an supplementary cementitious material, this paper compared the grinding and cementitious properties of granulated blast furnace slag and yellow phosphorus slag, and analyzed and compared their properties as supplementary cementitious materials. The results show that granulated blast furnace slag and yellow phosphorus slag have similar chemical composition and mineral phase. After the same grinding time, the particle size distribution, specific surface area and microstructure of granulated blast furnace slag and yellow phosphorus slag are similar. The increase of specific surface area of granulated blast furnace slag and yellow phosphorus slag promotes the hydration of cement and improves the activity of granulated blast furnace slag and yellow phosphorus slag, and the activity of granulated blast furnace slag is higher than that of yellow phosphorus slag under similar specific surface area. The addition of granulated blast furnace slag and yellow phosphorus slag has a great contribution to the later strength of cement mortar. The later strength of cement mortar increases with the increase of specific surface area of granulated blast furnace slag and yellow phosphorus slag. When the specific surface area of granulated blast furnace slag and yellow phosphorus slag is 340 and 521 m²/kg, respectively, the 28 d compressive strength of cement mortar with 30% (mass fraction) granulated blast furnace slag and yellow phosphorus slag is 46.5 and 47.3 MPa, respectively, which is higher than that of pure cement mortar. When the specific surface area of granulated blast furnace slag and yellow phosphorus slag is 775 and 802 m²/kg, the 28 d compressive strength of cement mortar is 58.7 and 50.9 MPa, respectively. In general, yellow phosphorus slag is an available supplementary cementitious material with high activity in this study, but attention should be paid to the retarding effect of yellow phosphorus slag on cement-based materials.

Key words: granulated blast furnace slag, yellow phosphorus slag, particle size distribution, strength, hydration heat, supplementary cementitious material
