Example Embodiment
[0020] Example 1:
[0021] The raw material ratio of this example is:
[0022] Construction waste concrete: 35 copies
[0023] Building waste brick powder: 50 copies
[0024] Cement: 15 parts
[0025] The production method is:
[0026] 1. Construction waste is used after classification and screening;
[0027] 2. Mix construction waste concrete, construction waste brick powder and cement in a mixer for 10 minutes. Add water to make the wet base moisture content 16%. After mixing, use 20MPa pressure on the molding equipment to form a molding. Naturally maintain at least 28 day.
[0028] In this example, the construction waste concrete brick meets the requirements of the agricultural industry standard of the People's Republic of China "Concrete Ordinary Bricks and Decorative Bricks" (NY / T671-2003), and the average compressive strength is above 15.7MPa and the average flexural strength is above 3.9MPa.
Example Embodiment
[0029] Example 2:
[0030] The raw material ratio of this example is:
[0031] Construction waste concrete: 20 copies
[0032] Building waste brick powder: 70 copies
[0033] Cement: 10 parts
[0034] The preparation method is:
[0035] After being classified and sieved, the construction waste is mixed with cement in a mixer for 10 minutes, and an appropriate amount of water is added to make the moisture content of the wet base 12%, forming under a pressure of 15MPa, and natural curing for 28 days. Its performance meets the requirements of the agricultural industry standard of the People's Republic of China "Concrete Ordinary Bricks and Decorative Bricks" (NY / T671-2003). The average compressive strength is above 18.9MPa, and the average flexural strength is above 4.6MPa.
