Many byproducts and waste materials with pozzolanic properties can substitute natural raw materials in cement production. Some of these waste materials like fly ash and blast furnace slag are commonly harnessed by cement industry. Others are of seldom use due to limitations of the very centralized cement production systems currently in use. In the authors opinion, it is necessary to change this system to enable efficient utilization of various waste materials that are available locally (e.g., white and red ceramics). In this study, a new partially centralized system of cement production is proposed. The adoption of a new system would significantly reduce the volume of long-distance transportation and enable utilization of numerous locally available waste materials that are currently dismissed. The last stage of production of the ready-to-use cement would take place in situ. The cement would be produced on demand and be immediately used for concrete production on-site. The research program was conducted considering the importance of the quality of cements obtained in the new way, substituting up to 12% of its mass by white ceramics. The research program was proof of concept of the proposed cement production system. It was shown that the quality of "in situ cement" does not differ from standard cements.
许多具有火山灰特性的副产品和废料可以替代水泥生产中的天然原材料。其中一些废料，如粉煤灰和高炉矿渣，已被水泥行业普遍利用。而其他一些废料由于目前使用的水泥生产系统高度集中的局限性，很少得到利用。在作者看来，有必要改变这种系统，以便能够有效利用当地可得的各种废料（如白色和红色陶瓷）。在本研究中，提出了一种新的部分集中式水泥生产系统。采用新系统将显著减少长途运输量，并能够利用目前被丢弃的大量当地可得废料。成品水泥生产的最后阶段将在现场进行。水泥将按需生产，并立即用于现场混凝土生产。考虑到以新方法获得的水泥质量的重要性开展了研究项目，用白色陶瓷替代其质量的12%。该研究项目证明了所提议的水泥生产系统的概念。结果表明，“现场水泥”的质量与标准水泥并无差异。
