Building sand

Our factory is a large mining enterprise integrating mining, production, processing and sales. It has processing, mineral processing, packaging, warehousing and other workshops, and has modern laboratory testing equipment. My factory is located in Taihang Mountain, taking full advantage of the local advantage and rich mineral resources, and introducing a complete set of advanced production equipment, set up a first-class level of management system, and gallop to the experts in the chemical mineral processing industry to carry out scientific management and strictly control the quality of the products.
"Quality first, integrity cooperation, user first" is our factory's business objective. We sincerely welcome friends from home and abroad to cooperate and work together to create the future together.
The building sand produced by our company is specialized in building thermal insulation sand paddle, casting, sewage treatment, artificial sand beach and other industries.
The products are dried, sieved, separated, dried and dried.
Main specifications: 6-8 mesh, 8-10 mesh, 10-20 mesh, 20-40 mesh, 40-70 mesh, 70-120 mesh.
Aggregate with a particle size below 4.75 mm is called fine aggregate, commonly known as sand. The sand is divided into two types: natural sand and artificial sand. The building sand is a rock particle with a particle size less than 4.75 mm, which is formed by natural weathering, flow and separation and accumulation, but does not include the particles of soft rock and weathered rock. Construction sand includes river sand, Lake sand, mountain sand and desalinated sea sand. Building sand is the general name of the machine-made sand and mixed sand treated by soil removal.
Requirements for quality of fine aggregate (artificial sand and natural sand) in specification for hydraulic concrete construction 2001:
1, the fine aggregate should be hard, clean and good gradation; the fineness modulus of artificial sand and within the range of 2.4 ~ 2.8, the fineness modulus of natural sand should be within the range of 2.2 ~ 3. The use of mountain sand and coarse sand should be tested accordingly.
2. In the process of mining, fine aggregate should be tested regularly or according to the quantity of a certain amount of mining. In a period of potential harm, corresponding measures should be taken and proved by special tests.
3. The moisture content of fine aggregate should be kept stable. The moisture content of saturated sand surface of artificial sand should not exceed 6%. Accelerated dewatering measures should be taken when necessary.
