ABSTRACT
Now, there is an increasing emphasis on replacing building materials because of their significant level of CO2 amount production with those that have a smaller carbon footprint, in order to reduce the construction industry's share of the global production of this compound. There is an increase in the use of recycled materials, although this is still not a significant share of the production of building materials. A promising product is the waste from wood processing, which are chips of various types. They are currently used in the production of, among other things, fibre-cement board. An important factor is the parameters of the waste to be obtained, such as its quality, composition, or information on any processes it may have undergone. This article presents the results of a preliminary study of concrete samples with pine chips: the search for the optimum proportion of concrete mixture and waste in the mix, its workability, and the mortar's bending and compressive strength. By building on the properties of the concrete mix, which reaches its maximum strength value with time, the preparation time of plates is reduced by the pressing and drying process. The effect of the percentage of chips in the mix and the effect of chip fraction on mortar strength is tested. The research is conducted to determine the possibility of reusing wood waste in fibre-cement composites for construction applications.
