Background
Sand and stone are the raw materials with the largest amount in concrete, and the soil content of the sand has great influence on the working performance, mechanical property and durability of the concrete. In the prior art, the soil content in river sand is usually measured by adopting a screening method. The screening method comprises the following specific steps: firstly, drying and weighing sand to be detected; breaking up the earth in the sand without grinding the sand grains; screening sand to be detected by using a screen with a preset size; the part which is left in the screen after screening is used as sand grains and is screened out is soil; the soil content of the sand is then obtained by weighing the mass of soil being screened off.
For the machine-made sand, the mud content of the machine-made sand is measured by using a methylene blue method at present, and the MB value is used for reflecting the mud content of the machine-made sand. However, the methylene blue method is a method of relatively and qualitatively judging whether the mud content of the machine-made sand is mainly stone powder or mud powder, and cannot accurately reflect the mud content of the machine-made sand, and in many cases, the problem is difficult to describe.
Although the prior art can provide sieves with various void sizes, sand grains with smaller particle diameters are inevitably weighed as soil in the process of sieving by adopting a sieving method, and the sand grains with smaller particle sizes and the soil can become flying dust and fly away in the process of sieving. Whereas the methylene blue process suffers from natural inaccuracy. Due to the problems described above, there are large errors in the conventional sieve analysis or methylene blue method for determining the soil content in sand.
