Formwork plays a key role in ensuring the shape and surface structure of concrete structures. During the hardening process in the formwork, concrete reaches the required strength and final geometry. Formwork systems must be designed to allow proper maturation and maintain their shape. The oldest formwork method is based on the use of wooden boards and beams, with the formwork usually being manufactured on site for each individual structural element. This approach has become economically unjustified and time-inefficient in modern construction practice, which is why systemic formwork was developed. These combine formwork panels and support elements, which allows for faster assembly, multiple use and significantly higher productivity. As part of the task, we prepared a manual for the use of Peri system formwork in the construction of walls, columns and slabs. In addition, we developed an independent software application – a plug-in for calculating fresh concrete pressures on the formwork, which depends on several parameters (e.g. concreting speed, temperature, concrete consistency, etc.). The manual systematically presents methods for determining the maximum fresh concrete pressures on the formwork structure according to selected parameters. The use of the designed plug-in allows for significantly faster and more accurate determination of horizontal pressure of fresh concrete. Practical methods for assessing these pressures are shown on specific examples of structural elements. With this manual, we have combined in one place the key information necessary for the design and use of systemic formwork in construction practice.
