Description
技术领域 technical field
本发明属于水泥材料技术领域，特别涉及一种改性磷铝酸钙矿物。 The invention belongs to the technical field of cement materials, in particular to a modified calcium aluminophosphate mineral.
背景技术 Background technique
硅酸盐水泥是现今世界上在建筑领域用量最大、最广泛的胶凝材料。该水泥熟料主要是由C3S、C2S、C3A和C4AF四种矿物组成。该水泥水化产物主要是C-S-H凝胶、氢氧化钙和钙矾石（AFt）等。然而硅酸盐水泥越来越难以满足重点工程或特殊工程的性能和施工要求，其主要缺点是早期强度偏低、水化过程中体积收缩过大等。因此，满足特殊工程需求的特种胶凝材料的研究、开发和应用就具有十分重要的意义。 Portland cement is the most widely used cementitious material in the construction field in the world today. The cement clinker is mainly composed of four minerals: C 3 S, C 2 S, C 3 A and C 4 AF. The cement hydration products are mainly CSH gel, calcium hydroxide and ettringite (AFt). However, it is increasingly difficult for Portland cement to meet the performance and construction requirements of key projects or special projects. Its main disadvantages are low early strength and excessive volume shrinkage during hydration. Therefore, the research, development and application of special cementitious materials that meet special engineering needs are of great significance.
磷铝酸盐水泥是具有我国自主知识产权的新型特种水泥，是一种具有高性能、低碱性及生物相容性好的胶凝材料。该水泥熟料的主要矿相为：磷铝酸钙CaO·(1-x-y)Al2O3·xSiO2·yP2O5、磷酸钙CP1-x(Ax)、铝酸钙CA1-y(Py)和玻璃体。根据专利CN1498870A，该水泥特征之一在于水泥熟料中形成了一种三元磷铝酸钙相，其晶体结构属于等轴（立方）晶系，其X射线衍射一个主要的衍射花样范围为：d=0.3723-0.3754nm，0.2629-0.2650nm和0.2147-0.2160nm，其主要化学成分含量为：CaO·(1-x-y)Al2O3·xSiO2·yP2O5，x=0.146-0.206，y=0.048-0.081。作为磷铝酸盐水泥的主要特征矿物，磷铝酸钙的早期强度并不突出，对整个体系的强度贡献主要体现在中后期。 Aluminophosphate cement is a new type of special cement with my country's independent intellectual property rights. It is a cementitious material with high performance, low alkalinity and good biocompatibility. The main mineral phases of the cement clinker are: calcium aluminophosphate CaO·(1-xy)Al 2 O 3 ·xSiO 2 ·yP 2 O 5 , calcium phosphate CP 1-x (A x ), calcium aluminate CA 1 -y (P y ) and the vitreous body. According to the patent CN1498870A, one of the characteristics of this cement is that a ternary calcium aluminophosphate phase is formed in the cement clinker, and its crystal structure belongs to the equiaxed (cubic) crystal system. The main diffraction pattern range of X-ray diffraction is: d=0.3723-0.3754nm, 0.2629-0.2650nm and 0.2147-0.2160nm, its main chemical composition content is: CaO·(1-xy)Al 2 O 3 ·xSiO 2 ·yP 2 O 5 , x=0.146-0.206, y=0.048-0.081. As the main characteristic mineral of aluminophosphate cement, the early strength of calcium aluminophosphate is not outstanding, and the contribution to the strength of the whole system is mainly reflected in the middle and late stages.
由于Ba2+(Sr2+)半径比Ca2+大，因此Ba-O（Sr-O）键的键强要弱于Ca-O键。当Ba2+(Sr2+)进入矿相晶格取代Ca2+位置，会导致晶格畸变程度变大，稳定性下降，从而有望提高被取代晶体的水化活性。人们发现采用Ba2+(Sr2+)取代硅酸盐矿物中的Ca2+，取代后C3S、C2S矿物水化活性均得到提高；通过Ba2+(Sr2+)部分取代硫铝酸钙（C4A3S）中的Ca2+可以得到系列的硫铝酸钡钙矿物，其分子式为(3-x)CaO·xBa(Sr)O·3Al2O3·CaSO4，即C4-xBxA3S，它具有比C4A3S更为突出的早强特性。受上述研究启发，本发明提供的方法是将Ba2+(Sr2+)引入磷铝酸钙矿物中并取代矿物中的Ca2+，从而使得磷铝酸钙的晶体结构发生变形，激发磷铝酸钙矿物的早期水化活性，同时辅以CaSO4和Fe2O3降低煅烧温度。 Since the radius of Ba 2+ (Sr 2+ ) is larger than that of Ca 2+ , the bond strength of Ba-O (Sr-O) bond is weaker than that of Ca-O bond. When Ba 2+ (Sr 2+ ) enters the mineral phase lattice to replace the Ca 2+ position, the degree of lattice distortion will increase and the stability will decrease, which is expected to improve the hydration activity of the substituted crystal. It was found that by replacing Ca 2+ in silicate minerals with Ba 2+ (Sr 2+ ), the hydration activities of C 3 S and C 2 S minerals were improved ; Ca 2+ in calcium sulfoaluminate (C 4 A 3 S) can obtain a series of barium calcium sulfoaluminate minerals, whose molecular formula is (3-x)CaO·xBa(Sr)O·3Al 2 O 3 ·CaSO 4 , that is, C 4-x B x A 3 S, which has more prominent early strength characteristics than C 4 A 3 S. Inspired by the above studies, the method provided by the present invention is to introduce Ba 2+ (Sr 2+ ) into the calcium aluminophosphate mineral and replace Ca 2+ in the mineral, so that the crystal structure of the calcium aluminophosphate is deformed and the phosphorous Early hydration activity of calcium aluminate minerals, while supplemented with CaSO 4 and Fe 2 O 3 to reduce calcination temperature.
