Structural performance of concrete blocks with wood aggregates for the construction of medium and high-rise buildings

Concrete blocks are widely used elements in buildings, due to their low cost, good performance and ease of mounting on the walls. However, the low ductility and resistance to flexion, could harm the seismic-resistant behavior of buildings, especially in medium and high-rise buildings. However, the addition of recycled and abundant additives in Nature such as wood could improve the structural and seismic characteristics. This work analyzes and compares the performance and structural performance of ordinary concrete blocks, incorporating different types of wood additives (sawdust and wood shaving) in medium and high-height frames (4, 8, 12 and 16 stories). The modeling of the frames will use experimental results carried out in a laboratory at the University of Talca (Chile).
