Detailed Product Description: | Block Interior is not dense, rough surface, low block strength. The reasons are: improper ingredients, aerated concrete wallboard manufacturers, cement below normal; glue ratio is too large, insufficient binder; aggregate particle size distribution properly, too coarse aggregate; water-cement ratio is too large; Proportional Ratio metering allowed; short mixing time or stirring uneven; vibration time is short; less vibration; conservation does not meet the requirements. The solution is: Mix appropriate adjustments to increase the amount of cement, aggregate particle size distribution adjustment, aerated concrete wall, reducing the amount of the fines; reduced water-cement ratio, aerated concrete wall, extension of mixing time, reinforced molding mechanical vibration strength. The reason wallboard design is very sensitive to uneven settlement of foundation, the design of the foundation uneven settlement if underestimated, easy to produce cracks and bottom sill stepped wall vertical cracks in the wall. In addition, most of the roof at the eaves no insulation measures, leading to the top horizontal wall cracks generated ladder. Roof insulation material to be chosen at random, regardless of the role of reducing the temperature difference will lead to cracks. In the concrete columns and concrete small hollow phase junctions, lack of appropriate measures to control cracks. |
