Properties of Cellular Concrete for Filters

Renato César Maruyama and Gladis Camarini
Abstract—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.

Index Terms—Cellular foam concrete, mechanical properties, porosity, water absorption, water permeability.
