—Considering the trends of new materials in
Construction, the lightweight concrete with a density between
400 and 1800 kg/m³ has been the subject of several studies with
emphasis on particle size distribution of aggregates and their
raw materials. Some of the advantages of cellular concrete are
its lightness, resistance to freezing and thawing, good thermal
insulation and acoustics. It can be used as blocks, precast
masonry panels, filling and regularization of slabs to be
waterproofed. The aim of this work is to study the material
proportion that composes the cellular concrete, such as cement,
sand, admixtures and water. It was analyzed the composite in
the fresh and hardened state. Properties, such as compressive
strength, water permeability of the plates, water absorption by
immersion and by capillary rise were determined. The tests
followed the Brazilian Standards and took place in cylindrical,
prismatic and cubic specimens. It was made seven mixtures
with four different admixtures, TecFoam, TecFill, CO 436 and
Less S. The cellular concrete with TecFoam and Less S obtained
strength and porosity for filtering water.
