Abstract
The pore structure of concrete is a very important material property influencing the durability of concrete. Concrete pore structure is influenced, among others, by the composition of concrete, water/cement ratio, aeration or cracking [1]. The experiment described in this paper understands concrete cover to be 40 – 60 mm from the surface of the specimen.The paper focuses on the determination of air void content in different concrete mixtures by means of microscopic analysis. Mixtures differ in the amount of cement and plastifying agent added while maintaining the consistency of the fresh concrete. In order to determine the air void characteristics, the experiment used manual and automated microscopic analysis.
