本文从充分发挥水泥熟料矿物在水化过程中潜在活性的观点出发,论证了提高水泥中<20μm的熟料颗粒含量,并加入适量沸石和石灰石作复合微集料生产的一种节能水泥——微集料水泥的依据。制造该水泥宜采用分别粉磨而后混合的生产工艺。 试产水泥的熟料粉比表面积为4450cm~2/g,<20μm的颗粒含量为 65.6％。沸石、石灰石掺量分别为20％、10％。水泥性能与425号普通水泥类似。经使用反映良好。据估算,与普通水泥相比,生产这种水泥可节能约10％,增产约20％。
In this paper, from the point of view of giving full play to the potential activity of cement clinker minerals in the hydration process, an energy-saving cement that increases the content of clinker particles <20 μm in cement and incorporates appropriate amounts of zeolite and limestone for composite micro-aggregates is demonstrated. - The basis of micro-aggregate cement. It is advisable to use separate grinding and post-mixing production processes for the production of the cement. The specific surface area of clinker powder for trial cement production is 4450 cm 2 /g, and the content of particles less than 20 μm is 65.6%. Zeolite and limestone content were 20% and 10%, respectively. The cement performance is similar to that of No. 425 ordinary cement. Used well reflected. It is estimated that compared with ordinary cement, the production of this kind of cement can save energy by about 10% and increase production by about 20%.
