摘要

本文介绍了粒状高炉矿渣、天然超沸石、石灰石粉对多组分水泥性能影响的研究结果。研究发现，考虑到粒径分布[PSD]按体积和比表面积的影响，以及需水量、出血性、火山灰活性、水化热等物理因素对膏体和混凝土集性能影响指标的测定，不同成因矿物添加剂的协同组合:可加工性、标准强度、早期强度、全球变暖潜势，可获得技术优化的多组分硅酸盐水泥。结果表明:高早强CEMⅱ/B-M 42.5 R-LH多组分硅酸盐水泥的生产保证了各组分的分离磨矿，同时考虑了比表面积PSD，优化了矿渣、超沸石和石灰石粉的颗粒组成;

Performance of multicomponent Portland cements containing granulated blast furnace slag, zeolite, and limestone

The paper presents the results of research on the influence of granulated blast furnace slag, natural pozzolana [superzeolite], and limestone powder on the performance of multi-component cements. It was found that the synergistic combination of mineral additives of different genesis, taking into account the influence of the particle size distribution [PSD] by volume and surface area, as well as the determination of indicators of the influence of physical factors such as water demand, bleeding, pozzolanic activity, the heat of hydration on the set of properties of paste and concrete: workability, standard, and early strength, global warming potential, allows to obtain technologically optimized multi-component Portland cements. The results showed that the production of multi-component Portland cement with high early strength CEM II/B-M 42.5 R-LH ensures separate grinding of individual constituents, optimization of grain composition of slag, superzeolite, and limestone powder taking into account the PSD by surface area.
