Abstract
The utility model discloses a gradient renewable concrete sound barrier board, which comprises three layers of poured concrete, wherein each layer of the poured concrete has different raw material mix proportion, a replacement rate of renewable aggregate in the three layers of poured concrete is different, the source of the renewable aggregate adopted in two adjacent layers of concrete is also different, and little steel fiber is doped in the inner layer and the outer layer of concrete. The inner layer of the poured concrete has characteristics of large porosity and light weight as well as good sound absorption effect; the outer layer of the poured concrete has small porosity, is compacter than the inner layer of the poured concrete, and has good durability, large mass and good sound insulation effect; and since the performance of the inner layer and the outer layer of the poured concrete is greater in difference, the intermediate layer of the poured concrete is used as a transitional layer. The steel fiber which is doped in the inner layer and the outer layer guarantees the mechanical strength and flexibility of the sound barrier board. Since both the sound absorption material and the sound insulation material are concrete, the interface strength problem can be avoided. The sound barrier board is completely made of renewable aggregate and is formed in a way of prefabrication in factories and assembly on site. The sound barrier board has advantages of fast construction speed, good durability, good noise lowering effect, resource conservation, environmental protection and the like.

Further, being mixed with volumn concentration in the said internal layer concreting is 0.5～1.0% steel fibre; Be mixed with volumn concentration in the said outer concreting and be 0.5～1.0% steel fibre.
Preferable, the concrete pore rate of said concreting internal layer is bigger than the outer field concrete pore rate of concreting.The quality of said concreting internal layer is than the outer field light weight of concreting.
" porosity " of the utility model is meant that the material internal voids volume accounts for the percentage of its cumulative volume.
Preferable, the particle size range of the broken regeneration aggregate of producing of said decoration garbage is 5～15mm; The particle size range of the broken regeneration aggregate of producing of waste concrete is 5～15mm.
Fines in the internal layer of the utility model, middle level and the outer field concreting can adopt the natural fine aggregate, and like natural river sand, the particle size range of said fines is 0.075～5mm.
The steel fibre of the utility model preferably adopts the ordinary steel fiber, and the length range of said steel fibre is 10～20mm, and diameter range is 0.2～0.6mm.
The gradient recycled concrete sound barrier panel of the utility model; Proportioning raw materials in the concreting of each layer is different; The replacement rate of the regeneration aggregate in three layers of concreting is different; The regeneration aggregate source that the adjacent layer concrete is adopted is also different, and also is mixed with a small amount of steel fibre in the inside and outside layer concrete.
The gradient recycled concrete sound barrier panel of the utility model, concrete divide three layers to build, the match ratio difference that each layer is used.Being positioned at the inboard concreting internal layer employing decoration garbage regeneration aggregate of sound barrier panel is coarse aggregate, and it is big that this concreting has porosity, the characteristics of light weight, and its acoustically effective is relatively good; The outer employing of the concreting waste concrete regeneration aggregate that is positioned at the sound barrier panel outside is a coarse aggregate, and this concreting porosity is little, and quality is big, and finer and close than the concreting of inboard, its defening effect is relatively good, and its durability might as well; Since inside and outside two-layer concrete performance differ bigger, therefore the intermediate layer is set as transition zone.Inside and outside two layer concretes mix a spot of steel fibre when stirring, guaranteed the mechanical strength and the toughness of sound barrier panel.Because sound absorption, sound insulating material are concrete, so there is not the boundary strength problem.
The recycled concrete sound barrier panel of the gradient of the utility model adopts regenerated coarse aggregate to process fully, adopts prefabrication, and the mode of on-site consolidation has that speed of application is fast, good endurance, excellent noise reduction effect, economizes on resources, protects advantage such as environment.
