Description

Technical Field

[0001] The utility model relates to the technical field of fine aggregate methylene blue test, in particular to a fine aggregate methylene blue test device with automatic liquid addition. Background Art

[0002] At present, the methylene blue test method for fine aggregate is to reduce the sample to about 400g, dry it in an oven at (105±5)℃ to constant weight, and after cooling to room temperature, screen out particles larger than 2.36mm for use; weigh 200g of the sample to an accuracy of 0.1g, recorded as m. Pour the sample into a beaker containing (500±5)ml of distilled water, stir it with an impeller stirrer at a speed of (600±60)r / min for 5min to make it a suspension, and then continue to stir at a speed of (400±40)r / min until the end of the test.

[0003] In the second step, add 5 ml of methylene blue solution to the suspension, stir at a speed of (400 ± 40) r / min for at least 1 min, and then use a glass rod to dip a drop of suspension. Drop the suspension onto the filter paper, and the filter paper should be placed on an empty beaker or other support so that the surface of the filter paper does not contact any solid or liquid. If no color halo appears around the precipitate, add another 5 ml of methylene blue solution, continue stirring for 1 min, and then use a glass rod to dip a drop of suspension onto the filter paper. If no color halo still appears around the precipitate, repeat the above steps until a stable light blue halo of about 1 mm appears around the precipitate. At this time, continue stirring without adding methylene blue solution, and perform a staining test every 1 min. If the color halo disappears within 4 min, add another 5 ml of methylene blue solution. If the color halo disappears in the 5th minute, add another 2 mL of methylene blue solution. In both cases, stirring and staining tests should be continued until the color halo can last for 5 min.

[0004] However, the current test equipment can only stir the solution at a fixed time, and there is no way to automatically complete the contamination test. Therefore, the utility model proposes a fine aggregate methylene blue test equipment with automatic liquid addition to address the above shortcomings. Utility Model Content
