31.05.20221. Introduction. Aggregates are widely used in the field of construction, specifically in the manufacture of concrete. The increasing demand for concrete will result in an increase in the requirements of all concrete ingredients, including aggregates, which represent 60–70% of the total volume of the concrete [].Most of the aggregates used are obtained from natural

Lightweight architecture is an unusual approach to building construction. The materials are self-designable and are a combination of different substances, such as fibers, metals, polymers, woodchips, and clay particles. Avoiding molds and frames allows the building to adapt to different environments on its own.
