Abstract

The paper presents a study to determine the applicability of blended cements with low Portland clinker content in construction mortars, including special mortars. The main additives used in the study, in the form of ground granulated blast furnace slag and silica fly ash, were characterised by a similar grain composition of less than 40 μm. They were introduced into mortars as a replacement for Portland cement in amounts of 50 and 70 % and their mixtures in amounts not exceeding 70 %. Tests were carried out to determine the influence of the proportion, as well as the SiO2 and CaO content of the individual main components, on the strength parameters of the designed cements. The results show that these cements can be used in self-compacting concrete technology and in sealing mixtures for geoengineering applications, which are designed to perform soil reinforcement and sealing. The proposed technology for the production of CEM V and CEM VI cements, in addition to the favourable changes in their properties, results in a significant reduction in the energy required to produce these cements.

研究了低硅酸盐熟料与不同掺量的二氧化硅粉煤灰和高炉矿渣的水泥性能

本文研究了低硅酸盐熟料掺合水泥在建筑砂浆(包括特种砂浆)中的适用性。研究中使用的主要添加剂为磨碎的粒状高炉矿渣和二氧化硅粉煤灰，其颗粒组成相似，均小于40 μm。它们被引入砂浆中，作为波特兰水泥的替代品，其含量为50%和70%，其混合物的含量不超过70%。进行了试验，以确定比例以及各个主要组分的SiO2和CaO含量对设计水泥强度参数的影响。结果表明，这些水泥可用于自密实混凝土技术和地球工程应用的密封混合物，用于土体加固和密封。拟议的生产CEM V和CEM VI水泥的技术，除了其性能的有利变化外，还显著降低了生产这些水泥所需的能源。
