The process of production of paving stones requires the use of a rather small amount of water, which is a distinctive feature of a technology called vibration pressing. This is noteworthy, such a feature gives the paving gaped by vibration pressing a fairly strong structure. The entire production process consists of a large number of stages, and each of the of it does not proceed, without any hoods, which explains the unique characteristics and distinctive features of the product at the output. Firstly, a molding substance consisting of cement, aggregates, various additives and water is being prepared.
They usually take sand, crushed stone as aggregates, and they should be a homogeneous type, as well as have high strength for compressive force. Responsible for moisture -resistant indicators of the characteristics are increased by adding plasticizers to the substance. Coloring pigments allow you to achieve the required color. Taking into account the fact that factors such as atmospheric precipitation, sunlight and alkali, have an effect on paving stones all year, then the most stringent requirements are imposed on all components of the mixture.
