Industrial enterprises are being built on a large scale in the desert regions of Uzbekistan. Concrete remains the main material in construction to this day. However, there is an acute shortage of sand of normal size. In this regard, an urgent task is to find effective and affordable technological methods for improving the properties of cement paste, concrete mix, and concrete on dune sand and cement savings. Taking into account our previous studies, the main attention was paid to establishing quantitative dependencies, changing the properties of cement paste and concrete from the introduction of sand dune fillers modified with additives of acidic (SDFMAA) and basic (marl) nature into their composition and the influence of methods for preparing a mixture of conventional and separate.
