Effect of individual components on characteristics of cement composites with recyclate

摘要

This article deals with the exploitation of construction and demolition waste of mineral origin for the production of new concrete. The exploitation of recycled and recyclable materials for new construction is an important aspect of sustainable construction which should become a priority in the design and choice of building materials. With depleting natural resources new possibilities must be sought for the substitution of natural aggregates, where, thanks to its properties, brick or concrete recyclate represents a suitable alternative solution. By adding polymer fibres to concrete mixes fibre concrete is produced - a tough composite offering by its properties a new application potential in structures. The article presents findings from a study and analysis of the results of an experimental programme focused on the production of concrete and fibre concrete in which natural aggregates have been substituted with brick or concrete recyclate. The research results are analyzed to monitor the effect of individual components on the properties of tested composites.
