Effect of High Dosage Air-Entraining Admixture Usage on Micro Concrete Properties

In concrete production, because of air entraining admixtures (AEA) are used for a small percentage by weight of cement (in the range from 0.06% to 0.2%), there is a possible risk adding more admixture in concrete than calculated from personnel or equipments sensitivity errors. In this situation concretes strength and durability performances are diminishing. In this work, it was investigated the effect of high dosage air entraining admixture usage on mortar properties. It was carried out unit weight, flowability, setting time, air content, compressive strength, flexural strength, ultrasound velocity tests and microstrucural inspections on specimens which were produced with 5 different dosages including control. As a result of experiments, in case of using admixtures with overdose, there would be loss of quality of physical and mechanical properties of concrete, for this reason it is concluded that, there must be some legal regulations using chemical admixtures sensitively.
