Abstract

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 equipment’s
sensitivity errors. In this situation concrete’s 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.
