## 1 Introduction  
A composite is defined as a material made up of at least two components with different properties such that it has superior and/or new properties over those components taken separately. However, the given definition is not generally accepted and precise, but is intended to generalize the most common descriptive definitions. On its basis, it can be assumed that a cement composite is a composite of whom one of the basic components is cement. The most popular composites in which cement acts as a binder are: grout, mortar, and concrete [1]. By the term grout, we mean the material that results from the combination of water and cement. The leaven itself is rarely used in construction. Cement mortar is used much more often, e.g., for bricklaying, plastering, or making floor underlays. Standard cement mortar is a mixture of the appropriate proportions of cement, water, and sand. The composition of the mortar can be supplemented with additives and admixtures added to give the appropriate properties to the mixture or hardened mortar. Concrete is another material. It is the most widespread cement composite in the world. In addition to water, sand, and cement, concrete contains coarse aggregate. In concrete, as in the case of mortar, we use admixtures and additives, which, in standard concretes, allow us, for example, to obtain better working parameters of the mixture with the use of less water, or to improve the physical parameters of the hardened composite [2]. An additive to concrete can be called a fine-grained component added to the concrete mix, whose task is to improve its properties or obtain the special parameters of hardened concrete. The amount of additive is generally from 5% to 15% of the weight of the cement. The content of the additive should be taken into account in subsequent iterations of the calculations of the designed mixtures. There are two main types of additives. The first type is nearly inert additives, which are in turn divided into fillers and pigments. Pigments are used to tint the concrete to the desired color. The role of fillers is to fill the pores of the concrete mixture [3]. An additive typical for this group is limestone powder. Additives with latent hydraulic or pozzolanic properties are the second type of concrete additives. Their use leads to an improvement in the properties of concrete or the acquisition of special properties. Representatives of this group are silica fume or fly ash. The most popular methods of adding fillers to a cement composite are in the form of (i) cement replacement, (ii) aggregate replacement, and (iii) grout replacement. These methods are successfully applied to waste materials in the form of quartz dust, marble powder, powdered glass, or fly ash, added to concrete and mortar as fillers or additives that modify the properties of the mixture or the hardened cement composite [4]. The mere production of cement as a basic component of concretes and mortars also has an undesirable impact on the environment. During the production of 1 ton of this material, about 900 kg of carbon dioxide are emitted; therefore, the partial replacement of cement with another component may contribute to reducing CO\({}_{2}\) emissions to the atmosphere [5]. Granite powder is a waste material that results from the crushing or cutting of granite rocks for industrial purposes. In recent years, an increase in the amount of granite powder waste has been observed as a result of the development of the granite industry. The powder fraction of this material alone is currently not applicable, which exacerbates the problem of the proper management of this product. The improper storage of dry material in the form of heaps, which can easily spread in the environment, causes water pollution, changes in the pH of land intended for agricultural purposes, and air pollution in the vicinity of landfills.
