Abstract
<p><em>Concrete has now become the most important material in the world of modern construction. The strength and durability of concrete are key factors that influence the strength and stability of buildings and infrastructure. Porosity refers to the degree to which concrete has void space within its structure. The higher the level of porosity, the lower the compressive strength of the concrete. This research aims to investigate the effect of adding type F additive, Master Glenium Ace 8595, on changes in porosity and increasing the compressive strength of concrete. Through laboratory experiments, we carry out analyzes of aggregate, workability, porosity and compressive strength of concrete. The research results showed that all the aggregates tested were suitable for use. The workability test produced dilute criteria, while the average porosity obtained was 8.05%. Compressive strength testing produced an average value of 23.56 MPa, indicating an increase of 8.69% from the planned concrete quality. This research concludes that concrete porosity must be considered to increase the compressive strength of concrete, because it has a significant influence on density and compressive strength. By keeping porosity at a low level and compressive strength at a high level, it can ensure that the concrete structure has good resistance to loads and the environment, as well as reducing the risk of damage and maintenance.</em></p>
