The aim of this research is to obtain an environment friendly construction product as a brick unit based on wooden waste incorporated in concrete used for structural elements in case of low-rise building. This paper presents the structural behaviour of masonry walls made from hollow blocks with recycled wood chips. The influence of the percentage of wood chips variation, as well as of the length of the structural wall, on the load-bearing capacity of the masonry made with blocks that include wooden waste was analysed. The study highlights that the variation, from 4 to 6 m, of the wall length significantly influences the load-bearing capacity of the analysed masonry, while the variation of the percentage of wooden waste as wood chips relative to the volume of aggregates, 25% and 50%, causes small changes in achieving the bending or shear capacity of the masonry made with ecological blocks.

Nowadays, one of the most important problems is the waste produced by all industries, civil engineering, commerce or consumption of products. In the present study, the authors aimed to obtain a new building material based on wood chips waste produced from different industries. The design material properties are influenced by the wood chips' percentage in relation to the aggregate volume, embedded in cement. Therefore, it was proposed two mix recipes, materials A and B which contain 50 and 25 percentage of wood chips related to the aggregate volume. Tests were performed for bending (flexural tensile) strengths establishing. These mechanical performances are important properties for the design process of masonry products or structures and for proving their applicability. [ABSTRACT FROM AUTHOR]

Wood as building material has been used since ancient times due to its performance and generous applicability in implementation of various structural elements and building systems. The need to reduce losses in the process of implementing operational structures in construction, from excessive consumption of material has led to the development of new structural systems for wood construction and roofing structures. Frequently, modern structures of pitched roofs have in their composition systems made of prefabricated structural components and wood products. This paper examines several embodiments of wooden roofing structures, taking into account the structural system, materials and dimensions of lumber assortments and material consumption for various types of pitched roofs.
