: Introduction. The management of physical and chemical processes of structure formation of high performance cement composites can be provided at several scale levels through the use of modifiers of various nature and mechanism of action, in particular, micro- and nanoscale mineral additives of natural and technogenic origin. It is known that clays and carbonate rocks are promising raw materials to obtain mineral modifiers for cement systems. The purpose of this study was to establish the influence regularities of the prescription and technological parameters (material and granulometric compositions, temperature calcination) to obtain mineral additives based on calcined clays and carbonate rocks on their activity in cement systems. Methods and materials. Polymineral clays and carbonate rocks (dolomite and chalk) from several deposits of the Republic of Mordovia were used as raw materials for obtaining mineral additives. The specific surface area of modifiers was determined on the PSX-12 dispersion analysis device using the Kozeny-Carman method. The study of the granulometric composition of sedimentary rock powders was carried out by laser diffraction method. The research of physical-chemical processes occurring during the heat treatment of polymineral clays and carbonate rocks was carried out using the synchronous thermal analysis method. Optimization of calcination temperature of clay-carbonate mixtures was carried out based on the research results on the effect of their additives on the cement binder activity with the determination of the modifier activity index in accordance with the methodology of the Russian State Standard GOST R 56178-2014. Results and discussion. The optimum calcination temperature, located for polymineral clays in the area of 500–800 о C, was established according to the study results of dehydration processes of clay minerals using the synchronous thermal analysis. This temperature range corresponds to the initial restructuring processes in the crystal structure of minerals of the kaolinite and illite groups, associated with their dehydroxylation, which contributes to the transition of these phases to the active form. The study results of influence of additives of calcined clay-carbonate mixtures on the cement binder activity proved the thermal analysis data. It was found that calcination of clays and clay-carbonate mixtures at 700°C contributes to obtaining of the most effective mineral modifiers. Conclusions. On the totality of studies, regularities were revealed in the system “modifier composition – calcination temperature of sedimentary rocks – mixed binder activity”, which allow optimizing the prescription and technological parameters for obtaining mineral additives to achieve the required level of strength characteristics of cement composites.
:介绍。通过使用各种性质和作用机制的改性剂，特别是天然和技术来源的微纳米级矿物添加剂，可以在几个尺度上提供高性能水泥复合材料结构形成的物理和化学过程的管理。众所周知，粘土和碳酸盐岩是获得水泥体系矿物改性剂的有前途的原料。本研究的目的是建立基于煅烧粘土和碳酸盐岩的矿物添加剂的配方和工艺参数(材料和粒度组成、煅烧温度)对其在水泥体系中的活性的影响规律。方法和材料。多矿物粘土和碳酸盐岩(白云石和白垩)从摩尔多瓦共和国的几个矿床被用作原料，以获得矿物添加剂。在PSX-12色散分析装置上用Kozeny-Carman法测定了改性剂的比表面积。采用激光衍射法对沉积岩粉末的粒度组成进行了研究。采用同步热分析方法对多矿物粘土和碳酸盐岩热处理过程中的物理化学过程进行了研究。根据粘土-碳酸盐混合料外加剂对水泥粘结剂活性影响的研究结果，根据俄罗斯国家标准GOST R 56178-2014的方法测定改性剂活性指数，对粘土-碳酸盐混合料的煅烧温度进行优化。结果和讨论。根据黏土矿物脱水过程的同步热分析结果，确定了多矿物粘土的最佳煅烧温度在500 ~ 800℃范围内。这个温度范围对应于高岭石和伊利石基团矿物晶体结构的初始重组过程，与它们的去羟基化有关，这有助于这些相向活性形式的转变。煅烧粘土-碳酸盐混合料中添加剂对水泥粘结剂活性影响的研究结果证实了热分析数据的正确性。结果表明，在700℃下煅烧粘土和粘土-碳酸盐混合物有助于获得最有效的矿物改性剂。结论。综合研究，揭示了“改性剂组成-沉积岩煅烧温度-混合粘结剂活性”体系的规律，从而优化了矿物添加剂的配方和工艺参数，使水泥复合材料的强度特性达到所要求的水平。
