Embodiment 1

[0031] Example 1 , Clay brick recycled aggregate preparation

[0032] Sorting waste clay bricks from brick-concrete structure construction waste and reinforced concrete structure construction waste by mechanical or manual methods can be divided into:

[0033] Construction waste at the construction site: Clay bricks, concrete, waste wood blocks, waste plastics, waste ceramics, etc. in the construction waste are sorted and piled up on the construction site.

[0034] Factory construction waste: The collected construction waste is sorted and stacked according to brick-concrete construction waste and reinforced concrete construction waste, and clay bricks are sorted from brick-concrete construction waste and reinforced concrete construction waste.

[0035] The clay brick recycled aggregate is broken into two kinds of clay brick aggregate with particle size below 3mm and 3-10mm by crushing equipment such as jaw crusher, impact crusher, cone crusher, impact crusher or hammer crushe...

Embodiment 2

[0036] Example 2 , Prepare clay brick recycled aggregate concrete partition wall slab components

[0037] According to the formula shown in Table 1, measure the components of the partition wall slats in proportion, add water according to the water-cement ratio of 0.3-0.45, and stir in the mixer to mix the components evenly for later use.

[0038] Table 1

[0039]

Embodiment 3

[0040] Example 3 , Production of clay brick recycled aggregate concrete partition wall slats

[0041] Follow the steps below to prepare clay brick recycled aggregate concrete partition wall slats:

[0042] A, the components of the partition wall batten shown in Table 1 of Example 2 are measured in proportion, add water according to the water-cement ratio 0.3-0.45, mix and stir;

[0043] B. Send the uniformly stirred components into a screw extruder for extrusion molding;

[0044] C. Cut the formed sheet into required specifications;

[0045] D, from the board;

[0046] E. Packing and binding;

[0047] F. Natural conservation or steam conservation.

[0048] The size of the clay brick recycled aggregate concrete partition wall slab made according to the above method has three specifications: length × width × thickness = 2500-3000mm × 600mm × 60mm; 2500-3000mm × 600mm × 90mm; 2500-3000mm × 600mm × 120mm .

[0049] The molded clay brick recycled aggregate concrete partitio...

Abstract

The invention discloses a clay brick regenerative aggregate concrete partition lath. The partition lath is manufactured by the following components by volume percentage: 60 to 70 percent of clay brick regenerative aggregate, 20 to 25 percent of cement, 0 to 5 percent of building sand, 0 to 15 percent of coal ash, 0 to 5 percent of expanded perlite, 0 to 5 percent of new or waste polyphenyl granules, 0 to 2 percent of fibers, 1 to 3 percent of cement modified polymer emulsion, and 2 percent of additive. The invention also discloses a method for manufacturing the clay brick regenerative aggregate concrete partition lath. The clay brick regenerative aggregate concrete partition lath has proper density, excellent performances on strength, shrinkage value, sound insulation and the like, is favorable for controlling crack on wall surfaces, has manpower tolerable range on installation construction of the lath, and realizes high added value utilization of building waste.

Description

technical field [0001] The invention relates to a building wall panel, in particular to a clay brick recycled aggregate concrete partition wall strip. Background technique [0002] The main components of my country's construction waste are waste clay bricks, waste concrete, waste ceramics, waste glass, waste plastics, and waste wood blocks. The transformation of construction waste into wall materials with mineralization characteristics is one of the development directions of construction waste resources. The scientific method of transforming construction waste into wall materials is to classify and utilize construction waste according to the building function requirements of different wall materials and the characteristics of different construction waste materials, so as to produce high-value-added wall products with outstanding performance. [0003] Most of the existing domestic production technologies for construction waste used in wall materials are extensive constructio...
