Air Entrainment Series

Since recent studies have shown that uniformly distributed entrained air improves the properties of concrete in many ways and also considerably improves the workability of fresh concrete, their use in all major construction works involving mass concreting is now being widely adopted. Though entrainment of correct proportion of air gives the concrete good weathering resistance, too much of it affects the strength while too little causes rapid deterioration by weathering. As such, control of the air content in fresh concrete to optimum proportion before its placement through regular test checks by right type of equipment is very important.

HEICO offers two different models of air entrainment meters; that is type A and type B for estimation of air content of concrete mixes having different maximum sized aggregates. They are pressure type instruments and use the principle of Boyle’s law for indication of air content in the concrete
