Comportamento de misturas entre solo e bentonita para uso em núcleos de barragens de terra.

Abstract

It was reported some results obtained from a research to show that mixing soil with montmorilonitic clays (bentonita) should contribute to identify information and process to choose materiais of construction to earthfill core dams. It was analyzed two types of soils from a northeast region of Brazil called the "Planalto da Borborema". Plain soil and their mixes with bentonita were tested in laboratory. The obtained data were useful to classify soil and their mixes using the Unified Soil Classification System and to identify properties from those material and mixes that should contribute to foresight their behavior as materiais of construction to earthfill core dams.
