Recycled products, including recycled aggregates, recycled permeable bricks, unfired bricks, and recycled inorganic binders, offer significant economic and environmental advantages. However, these products, made from recycled aggregates, exhibit significant water absorption rates and absorption rates, making them key indicators for performance improvement and application research.

[0050] Example 2

[0051] This embodiment is further limited on the basis of embodiment 1. This embodiment provides a method for detecting the water absorption rate of construction solid waste recycling products, using detection equipment, including air tightness testing and water absorption rate testing.

[0052] The air tightness test comprises the following steps:

[0053] A. Close water stop valves A5, B6, and C7, and fill the water supply bottle 1 and sample container 9 with test water 18;

[0054] B. Open the exhaust water stop valve 14, install the cover plate 16 on the sample container 9, open the water stop valve A5 and the water stop valve B6 in sequence, and inject the test water 18 in the water bottle 1 into the glass tube 12 along the water bottle connecting pipe 4. When the water head height approaches the upper limit of the scale mark on the glass tube 12, close the water stop valve A5 and observe whether the liquid level in the glass tube 12 is stable;

[0055] C. Open the water stop valve C7 and inject the test water 18 in the water supply bottle 1 into the sample container 9 through the water inlet pipe 8. Observe the removal of bubbles in the sample container 9 through the transparent plate 15 until the air is completely removed by the exhaust water stop valve 14.

[0056] D. Close the water stop valve B6 and open the water stop valve A5. After the liquid level in the glass tube 12 stabilizes after 4-5 seconds, observe the leakage of the detection equipment. If there is no leakage, perform the water absorption rate test;

[0057] The water absorption rate detection comprises the following steps:

[0058] E. Close the water stop valve A5, water stop valve B6 and water stop valve C7, and fill the water supply bottle 1 and sample container 9 with test water 18.

[0059] Open the exhaust water stop valve 14, install the cover plate 16 on the sample container 9, open the water stop valve A5 and the water stop valve B6 in sequence, and inject the test water 18 in the water bottle 1 into the glass tube 12 along the water bottle connecting pipe 4. When the water head height approaches the upper limit of the scale mark on the glass tube 12, close the water stop valve A5 and the water stop valve B6, and wait for the liquid level in the glass tube 12 to stabilize;

[0060] F. Read the liquid level H in the glass tube 12. Remove the cover 16, place the recycled product 19 in the sample container 9, install the cover 16, open the water stop valve B6 and the water stop valve C7, exhaust the air in the sample container 9, close the water stop valve B6, open the water stop valve A5, and read the liquid level H1 in the glass tube 12 after 5 seconds. Then, read the liquid level H2, H3, etc. in the glass tube 12 at the specified time intervals until the test is completed. Calculate the results according to the following formula:

[0061] V w =(H i +1-H i ) / t i

[0062] Vw—water absorption rate in the i-th time interval;

[0064] t i is the i-th period.

[0065] In this embodiment, step B can be used to detect whether the glass tube 12 is leaking. After the liquid level in the glass tube 12 is stable, it can be determined that the glass tube 12 is not leaking.

[0066] In this embodiment, the air in the sample container 9 can be completely exhausted through step C. At the same time, by observing that the water level in the water supply bottle 1 is stable, it can be determined that the sample container 9 has no leakage.

[0067] In this embodiment, step D can be used to observe whether there is leakage between the glass tube 12 and the sample container 9. If the liquid level in the glass tube 12 is stable, it means that there is no leakage in the entire device and the water absorption rate test can be performed.

[0068] Assuming the equipment is leak-free and airtight, the water absorption rate is tested. By observing the drop in the liquid level in glass tube 12 over a period of time, the amount of water absorbed by the recycled product 19 during that period can be determined. Dividing this by the time taken can yield the water absorption rate. This technical solution enables rapid, accurate, and convenient water absorption rate testing of recycled construction solid waste products of varying types and sizes.
