Very poor analysis of orthogonal experiment is a visual analysis methods. The vitreous micro-bead insulation mortar dry density and 28 D of 10-90very poor results of the analysis are shown in Table 3.

Misses the analysis is extremely to the orthogonal experiment one direct-viewing analysis method.Melts the micro bead heat preservation mortar dry weight density and the 28d compressive strength side to Bolivia misses the analysis result to see Table 3 separately.

Very poor analysis is a Visual analysis of orthogonal experimental method. Glass bead insulating mortar dry density and compressive strength of 28D a spread of the results of the analysis as shown in table 3, respectively.
