Influence of the addition of pine chips waste on the properties of the concrete mix

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 - bending test and stretching test are used. The research is conducted to determine the possibility of reusing wood waste in fibre-cement composites for construction applications. Depending on the chip fraction, they gained positive characteristics, the beam with a finer fraction achieved greater strength, similar to a concrete beam. Unground chips, on the other hand, maintained the bond, which did not occur in the finer fraction.
