More Information
Summary:The invention relates to low hydration heat toughness well cementation cement. Belongs to the technical field of well cementation materials of well cementation engineering. The structural stability is good, the problems of high strength and low hydration heat of the well cementation cement stone can be fundamentally solved, and the long-term durability of the well cementation cement sheath is further realized. The preparation method comprises the following steps: mixing low-heat Portland cement clinker serving as a base material, silica fume serving as a mixed material and whiskers serving as a modifier with gypsum, and jointly grinding until the specific surface area is 350-450m < 2 >/kg, so as to prepare the low-hydration heat toughness well cementing cement. The low-heat Portland cement comprises the following main raw materials in parts by weight: 75-90 parts of low-heat Portland cement clinker, 0-16 parts of silica fume, 2.5-3.5 parts of low-heat admixture, 1-3 parts of whisker and 4.5 parts of gypsum.
