Results of Research into the Physical and Mechanical Properties of Biopolymer Gravel Composite Block Filters for Hydrogeological Wells

The article presents the results of a study of the physical and mechanical properties of a biopolymer gravel composite made on the basis of polylactide (PLA) and natural gravel. The developed composite is intended for filtration elements of hydrogeological wells. The biopolymer-gravel composite was tested for compressive strength. The results showed that the biopolymer gravel composite is characterized by sufficient mechanical strength and resistance to the effects of the aquatic environment, which confirms the feasibility of its use as an environmentally safe material for filtration elements of hydrogeological wells. The obtained data can be used for further optimization of the composition of the composite material and the development of new biopolymer block gravel filters of hydrogeological wells.
