The objective of this study is to analyze the effect of the air entrainment on the fresh rheological properties as well as on the compressive mechanical resistances of the mortars. The hardened concrete contains a certain amount of randomly spread air. coming either from a drive during kneading or from the evaporation of the mixing water. The air quantity is in the order of 20 l / m3. https://herbsdailyes.shop/product-category/macadamia/
