“…Thus, the adsorption of the molecules of organic substances that form the dead jellyfish mass (protein, glycogen, fat) on cement grains with the formation of hydrodynamic lubrication will cause a decrease in the internal friction of the components of the concrete mixture during its laying and compaction. A denser packing of the components forming the conglomerate will reduce the overall porosity of the material, as well as the average pore size [54].…”

Currently, there is an environmental problem associated with cleaning the seas and oceans from a large number of dead jellyfish thrown ashore and into the coastal zone, which is urgent and requires solutions. This research aims to study the formation and properties of cement and concrete with added jellyfish mass and to understand the effects of this addition. Tests were carried out on formulations containing dead jellyfish mass in amounts from 0.2% to 1.6%. This study focused on the density, shear stress, workability, water separation, strength, and water absorption of cement and concrete, which are the main properties that characterize cement and concrete in construction. Adding 0.6% dead jellyfish to this composition resulted in greater effectiveness compared to the control composition. With this dosage, the normal density of the cement paste decreased by 16.3%, there was a 32% decrease in ultimate shear stress, the workability expressed in the cone slump increased by 60.8%, the water separation of cement decreased by 19.7%, the increase in compressive strength was 10.6%, and water absorption decreased by 15.5%. An analysis of the structure showed that the modification of concrete with dead jellyfish mass reduces the defectiveness of a concrete structure compared to the composition of the control structure.
