Man-made waste is the dominant component of knitting compositions

Improving the quality and durability of construction materials while simultaneously reducing the costs of their production and use remains a pressing issue in construction material science. Analyzing the industrial experience of using construction composites leads to the conclusion that new technologies are based on the dominant position of the active binder component, which is responsible for accelerating the hydration processes, targeted formation of the phase composition, and modification of the structure of the cement paste. Combining clinker and mineral components, incorporating chemical modifiers, and properly designing the formulation and preparation technology of the binder composition and concrete mix makes it possible to achieve the desired design strength, reduce cement consumption, and lower product cost. This paper presents the results of studying a complex pozzolanic additive, whose material composition enables the formation of a denser stone structure due to an additional active source of unhydrated calcium silicates and sodium/calcium aluminosilicates. The resulting filled binder exhibits properties significantly superior to control samples. Using local inert materials and achieving a 25% reduction in clinker, concrete mixes of classes B20–22.5 were developed. These are widely used in the casting of foundations, floor slabs, stair flights, paving elements, and other concrete and reinforced concrete products.
