Cementing material and preparation method thereof
The invention provides a cementing material and a preparation method thereof. The cementing material provided by the invention comprises the following raw materials: a base material and an additive, the mass of the additive is 1%-5% of the mass of the base material; the base material comprises the following components in percentage by mass: 40%-70% of pretreated drilling oil sludge, 10%-40% of fly ash, 10%-20% of steel slag and 5%-10% of desulfurized gypsum; wherein the pretreated drilling oil sludge is obtained by the following steps: mixing a NaOH aqueous solution with drilling oil sludge, standing and aging to obtain the pretreated drilling oil sludge. The cementing material provided by the invention adopts the pretreated drilling oil sludge as a main raw material, so that the cementing material can be prepared, good mechanical properties can be obtained, and the problems of idle stacking and land occupation of the drilling oil sludge are solved.
本发明提供了一种胶凝材料及其制备方法。本发明提供的胶凝材料的原料包括：基料和添加剂；所述添加剂的质量为所述基料质量的1％～5％；所述基料包括以下质量比的组分：40％～70％的预处理钻井油泥，10％～40％的粉煤灰，10％～20％的钢渣，5％～10％的脱硫石膏；其中，所述预处理钻井油泥通过以下方式获得：将NaOH水溶液与钻井油泥混合后，静置陈化，得到预处理钻井油泥。本发明提供的胶凝材料采用预处理钻井油泥作为主要原料，不仅能够制备出胶凝材料，而且能够获得良好的力学性能，还解决了钻井油泥闲置堆放、占用土地的问题。
