“…Since the last two decades, many hardfill dams and road embankments have been constructed around world concerning many extensive advantages in comparison with conventional embankments [2][3][4][5][6][7]. While the technology of hardfill dams was established in recent decades, many researchers focused on developing and optimizing new aspects of hardfill dam design [8][9][10][11][12][13][14][15].…”

The hardfill embankments are composed of cemented sand-gravel (CSG) mixtures. In some cases, however, sand and gravel used in the mixture contain fine-grained fraction. This paper aimed to study the mechanical behavior and microstructure of CSG mixtures in which the base soil contains fine-grained particles with different plasticity specifications. Various contents of kaolinite and bentonite were added to a sand-cement mixture with different cement contents and uniaxial strength and deformation modulus in the mixtures were measured at two curing ages. According to the results, in low cement mixtures, the mixture containing 10% of the additive exhibited the maximum strength and deformation modulus, regardless of the additive type. In a family of bentonite-containing mixtures with higher cement, the strength of mixtures decreased with increasing the bentonite content. However, the mixture with higher cement and 10% of kaolinite presented the best performance from in terms of strength and stiffness. Analyzing the mineralogy and SEM images of mixtures showed that the structure of base soil attained the best packing and a strong matrix was devolved inside the mixture with 10% of fine additive. Furthermore, the kaolinite particles in the mixture containing 10% kaolinite contributed to the hydration process of cement.

The article presents studies of the stress-strain state of a gravity dam of a homogeneous symmetrical profile made of cement-sandand gravel (CSG) on a rocky base. When performing computational studies, the method of full factorial experiment (PFE) was used. Based on this method, we take three variations factors the dam height, slope ratio, and the modulus of deformation of the dam. Calculations were carried out using the CRACK software package. The results allow us to optimize the dam profile (CSG) in a real project and evaluate the reliability of dam structures of this type.
