Abstract
: This publication presents the results of a study of the effect of partial replacement of cement with waste and natural materials: ground blast furnace slag, fly ash and lime meal on the strength properties of mortars compared to a reference mortar without these additives. In subsequent tests, these materials were gradually replaced with up to 10% CEM I cement. Their effects on consistency and compressive and flexural tensile strengths after 28 days of maturation were investigated. The tests were carried out on blocks measuring 40 mm × 40 mm × 160 mm according to the standard. In the range of tests analysed, the results obtained make it feasible to consider the possibility of partially replacing cement with silica fly ash and ground granulated blast furnace slag in cement mortars.
本出版物介绍了一项研究结果，研究了用废弃和天然材料(磨碎的高炉矿渣、粉煤灰和石灰粉)部分替代水泥对砂浆强度性能的影响，并与不含这些添加剂的参考砂浆进行了比较。在随后的测试中，这些材料逐渐被高达10%的CEM I水泥取代。研究了其对28 d成熟后稠度和抗压、抗折强度的影响。试验采用标准尺寸为40 mm × 40 mm × 160 mm的砌块进行。在所分析的试验范围内，所获得的结果表明，可以考虑在水泥砂浆中用硅粉煤灰和磨碎的高炉矿渣部分替代水泥的可能性。
