Abstract: The mechanical properties of three kinds of mixture ratio, thermal insulation glazed
hollow bead concrete performance and experimental study on impermeability, appropriate to
relax the conditions on thermal insulation performance requirements, preparation of thermal
insulation glazed hollow beadand anti permeability of high performance concrete, the concrete
strength grade of C40, heat conduction coefficient is W/ (M · K), anti permeability
levelgreater than P14, unilateral cement dosage is 410kg, compared with theordinary concrete test,
both significantly reduced the amount of cement.
Key words: Thermal insulation glazed hollow bead concrete; durability; impermeability;
high-performance
