[0013] Preferably, a method for detecting the carbon dioxide adsorption and solidification capacity of carbon-fixing concrete comprises the following steps:

[0014] Step 1: When it is necessary to test a certain ratio of concrete, first put the ingredients of this ratio of concrete (coarse and fine aggregates, cement, mine tailings, admixtures and tap water) into the waterproof geotextile bag, and use the splicing mechanism to fix the waterproof geotextile bag under the guide rod; open the hydraulic rod, and the hydraulic rod is extended to drive the fixing seat and the waterproof geotextile bag to move downward, so that the waterproof geotextile bag enters the interior of the cylinder, and the hook at the bottom of the waterproof geotextile bag hooks the hanging ring, and the hydraulic rod continues to extend, the waterproof geotextile bag contacts the inclined rod, and the waterproof geotextile bag is not in a relaxed state;

[0015] Step 2: Turn on the variable frequency motor, and the operation of the variable frequency motor drives the fixing seat and the waterproof geotextile bag to rotate. When the guide rod and the waterproof geotextile bag rotate, since the hook hooks the hanging ring, the guide rod drives the top of the waterproof geotextile bag to start twisting, and the waterproof geotextile bag is in a relaxed state at this time, and the guide rod is rotationally connected to the fixing seat, and the guide rod rotates at the bottom end of the fixing seat, so that the guide rod rotates and continuously twists the waterproof geotextile bag, so that the air inside the waterproof geotextile bag is quickly pressed out through the air inlet pipe to remove the gas inside the waterproof geotextile bag; a certain amount of carbon dioxide is injected into the waterproof geotextile bag through the air inlet pipe, and the valve is closed; water is injected into the interior of the storage mechanism, and the volume V of the waterproof geotextile bag at this time is obtained by the immersion method;

After a period of time, the volume V of the waterproof geotextile bag at this time is obtained by the immersion method, and the duration T since the start of carbon dioxide filling is recorded, and the volume difference between V and V is calculated. The smaller the volume difference between V and V, the shorter the duration T, and the better the effect of concrete adsorption and solidification of carbon dioxide.

Since the hook hooks the hanging ring, the top of the waterproof geotextile bag starts to twist at this time, so that the air inside the waterproof geotextile bag is quickly pressed out, and the gas inside the waterproof geotextile bag is removed; then a certain amount of carbon dioxide is injected into the waterproof geotextile bag, and water is added into the storage mechanism. The volume V1 of the waterproof geotextile bag at this time is obtained by the immersion method, and the The hook is separated from the hanging ring, and the driving mechanism is opened, so that the driving mechanism drives the waterproof geotextile bag to move up and down continuously, so that the waterproof geotextile bag contacts the inclined rod, and the guide rod is rotatably connected to the fixed seat. When the guide rod rotates, under the action of centrifugal force, the waterproof geotextile bag rotates slowly and approaches the inner wall of the storage mechanism, so that the concrete and carbon dioxide are fully in contact inside the waterproof geotextile bag. After a period of time, the volume V2 of the waterproof geotextile bag at this time is obtained by the immersion method, and the duration T since the start of carbon dioxide filling is recorded, and the volume difference between V2 and V1 is calculated. The smaller the volume difference between V2 and V1, the shorter the duration T, and the better the effect of concrete adsorption and solidification of carbon dioxide.

When the guide rod (52) and the waterproof geotextile bag (54) rotate, the hook (55) hooks the hanging ring (57), and the guide rod (52) drives the top of the waterproof geotextile bag (54) to start twisting. At this time, the waterproof geotextile bag (54) is in a relaxed state, and the guide rod (52) is rotatably connected to the fixed seat (51). The guide rod (52) is in a state of rotation. The bottom end of the fixing seat (51) is rotated, so that the guide rod (52) is rotated to continuously twist the waterproof geotextile bag (54), so that the air inside the waterproof geotextile bag (54) is quickly pressed out through the air inlet pipe (53), and the gas inside the waterproof geotextile bag (54) is removed; a certain amount of carbon dioxide is injected into the waterproof geotextile bag (54) through the air inlet pipe (53), and the valve (58) is closed; water is injected into the interior of the storage mechanism (2), and the volume V1 of the waterproof geotextile bag at this time is obtained by the immersion method; Step 3: Separate the hook (55) from the hanging ring (57), turn on the variable frequency motor (42) and the hydraulic rod (41), thereby driving the waterproof geotextile bag (54) to continuously move up and down and rotate inside the cylinder (21), so that the waterproof geotextile bag (54) contacts the inclined rod (56), the inclined rod (56) squeezes the concrete and carbon dioxide, and the guide rod (52) is rotatably connected to the fixing seat (51). When the guide rod (52) rotates, under the action of centrifugal force, the guide rod (52) and the waterproof geotextile bag (54) rotate slowly and approach the inner wall of the cylinder (21), and the cylinder (21) ) squeeze the waterproof geotextile bag (54), so that the concrete and the carbon dioxide are fully in contact inside the waterproof geotextile bag (54). After a period of time, the volume V2 of the waterproof geotextile bag (54) at this time is obtained by the immersion method, and the duration T since the carbon dioxide filling begins is recorded, and the volume difference between V2 and V1 is calculated. The smaller the volume difference between V2 and V1, the shorter the duration T, and the better the effect of concrete adsorption and solidification of carbon dioxide. Through the above test, the ability of a proposed concrete mix ratio to adsorb and solidify carbon dioxide can be quickly measured, and the adsorption and solidification ability can be evaluated, so as to achieve the purpose of quickly selecting the appropriate preferred value of carbon fixation concrete raw materials.
