The sand is divided according to the method of extraction. The division into fractions is natural for this raw material. It can be large, medium or fine-grained.
Fine sand and its characteristics
The size of the fine-grained material does not exceed 2mm. It consists of rounded debris and angular minerals. The density estimate is determined by the porosity factor, which for fine-grained sand is 0.75, and its deformation modulus ranges from 30 to 50 MPa.
Scope of application
Developers want to buy fine sand in St. Petersburg for most construction work. It is a unique and good building material that is necessary at the stage of laying the foundation or masonry work. Sand is an irreplaceable raw material in the repairing process of the hotel. It is a good choice for preparing finishing plasters on interior or exterior wall surfaces. Fine sand is used in the production of refractory materials. For renovation work with marble or white stone decoration, use a white sand-based plaster mortar. This mortar is a good way to bond the stone to the substrate. The restoration work also uses a similar mix. It is widely used in landscaping, for example, filling paths in parks or summer cottages. The water-resistance of the fine-grained sand allows it to be used in drainage systems.
The advantage of this sand is that it is economical. It is cheaper to buy fine sand in St. Petersburg than coarse or medium-grained.
