The influence of organic substances on the properties of slag-lime concrete
Incoming article date: 13.10.2025The results of a study of the shrinkage, mechanical properties, and durability of slag-lime concrete modified with machine and vegetable oils are presented. To determine the effect of the oils, the physical and mechanical properties (setting time, compressive strength, and autogenous shrinkage) were tested. The experimental results show that using oil as a structure modifier for slag-lime concrete can significantly reduce its autogenous shrinkage by reducing surface tension and creating a denser internal structure. It was found that emulsified oils provide superior physical and mechanical properties to concrete compared to non-emulsified oils. The setting time is also longer than in compositions without an organic modifier. The use of emulsified oils reduces the negative properties of slag-lime concrete, such as shrinkage, cracking, and reduced setting time.
