ON THE QUESTION OF THE CONTACT ANGLE OF WETTING IN DETER-MINING THE HEIGHT OF THE CAPILLARY RISE IN SANDY SOILS

Abstract

The use of local materials in the design of hydraulic structures of reclamation systems will significantly reduce their cost. Object. The objects of research are sapropels, sands and mixtures based on them. Materials and methods. Standard methods were used to deter-mine particle size distribution, porosity, density, and capillary rise height. Results and conclusions. The analysis of the data obtained showed good convergence of the experi-mental one after 1 day and the theoretical heights of the capillary rise for sands at a con-tact angle of 30
