The concrete is prepared by using the glazed hollow bead selected as the main fine aggregate, cement, gravel,water and so on. Some tests of the physical and mechanical properties and masonry mechanical properties on the load-bearing bricks made using the optimal mixing proportion got by the orthogonal experiment are carried out. The results show that all the physical and mechanical properties can conform to the technical requirements of the solid concrete brick, meanwhile, the birick has the features such as lightweight and thermal insulation, which is a great significance for improving building energy saving. The results of masonry mechanical properties test indicate that the calculation value of masonry axial compressive strength is closed to the calculated value of concrete block in specification. In order to get the better fitting, the suggestive value of α is given. The calculation value of shear strength is slightly smaller than the average of measuring value, and it conforms to the requirements of the specification.
