Description

technical field [0001] The invention relates to a recycled heat-preservation concrete made of steel fiber polystyrene particles and a preparation method thereof, belonging to the technical field of building materials. Background technique [0002] Building exterior wall is the main part of building energy consumption, and its energy-saving technology has become the focus of research in all countries that attach importance to environmental protection and energy conservation. Since the load-bearing and thermal insulation functions of the building are completed by two kinds of system materials, and the construction cannot be carried out at the same time, it brings problems such as increased cost and complicated construction. According to the system engineering theory, the energy saving of building materials cannot only be considered in a certain link in the production or use process. If there is no system engineering point of view, the design and production of building materia...
