Foamed concrete (FC) is a high-quality building material with densities from 300 to 1850 kg/m3, which can have potential use in civil engineering, both as insulation from heat and sound, and for load-bearing structures. They also lower the permeability of concrete and thus reduce bleeding of water. B. Chiaia, A. Fantilli, P.

Besides the properties of fiber-reinforced concrete, the structural performance of the structures made of fiber-reinforced concrete was investigated and discussed in this special issue. endstream endobj startxref 0 Get the latest journals, research papers, DOC and PDF documents discussing the need of using various types of fibers like synthetic, steel, glass etc. For this reason, mixtures proposed for use in de-sign should be tested, preferably in specimens repre-senting the end use, to verify the property values as- sumed for design.
