In the article, the authors presented the results of research on the assessment of the effect of selected mineral additives on the strength properties of the standard mortar. The modification of the composition of the standard mortar made on the basis of CEM I 42.5R cement and quartz sand consisted of using seven selected mineral additives in the form of compacted microsilica, Mikrosill microsilica, limestone flour, glass flour, glass granulate, basalt flour, and fly ash in the amounts of 10 and 20% in relation to cement as its substitute. Reducing the share of cement in the standard mortar by 10% has a beneficial effect on improving the compressive strength by over 40% with the addition of microsilica, and in the case of bending strength, even by 10%.
在该文章中，作者展示了关于评估所选矿物添加剂对标准砂浆强度性能影响的研究结果。基于CEM I 42.5R水泥和石英砂制成的标准砂浆成分改性，包括使用七种所选矿物添加剂，分别为压实微硅粉、Mikrosill微硅粉、石灰石粉、玻璃粉、玻璃颗粒、玄武岩粉和粉煤灰，其用量为水泥用量的10%和20%，作为水泥替代品。在添加微硅粉的情况下，将标准砂浆中水泥的份额减少10%对提高抗压强度有超过40%的有益效果，而对于抗弯强度，甚至提高了10%。
