INTRODUCTION The following report is the details of an experiment that’s designed to study the effect of the admixture air entrainment on a control concrete at a pre-determined water- cement ratio. The factors analyzed are slump, air content, and 28-day compressive strength. Air-entrainment admixtures are added to concrete with the intention of stabilizing microscopic air bubbles. Proper air-entrainment can greatly improve concrete’s durability against freeze-thaw, improve resistance to scaling caused by deicers, improve fresh concrete workability, and reduce segregation and bleeding. The control mix of concrete is to be non-air-entrained with the design slump of 4”, and the NMS of coarse aggregate of ¾”. The water/cement (w/c) ratio is 0.45. It is assumed that all mixes are generated from the same batch. Therefore, there is no batch-
