ABSTRACT

In order to solve the problems of low strength and brittle fracture of conventional concretes, ordinary cement was used as the main material of concrete binder, and porous glass beads processed from waste glass were used as aggregates to provide lightweight and fireproof insulation, and functional organic binding additives (including polymers) were added to improve concrete strength. Additional binding agents, such as silanes, were used to produce concrete-type lightweight materials with a specific gravity lower than water. The resulting materials thus manufactured have solved the problems of low work-ability and brittle fracture of conventional (ceramic) concretes, and exhibited excellent mechanical and thermal properties, with good fireproofing properties and low thermal conductivity at high temperatures. In addition, it can be molded into a certain space like conventional concrete, processed into bricks or thin boards in molds, or applied like paints, so it is believed that it can be applied to various structural materials.
