Abstract

Two sedimentar and two metamorphic limestone, separated in the sieves n°s (ABNT) 5-10, 10-30, 30-50, and 50-60 were incubated with three types of soils. The neutralizing efficiency was evaluated by pH variation. The results showed that their efficiency is independent of the geological nature of limestone but is dependent of soil type. The following efficiency value is suggested for each size fraction: larges than size 10 is 0%, size 10-30 is 35%, sizes 30-50 is 75% and smaller than size 50 is 100%.
