The fibers give the material a ductile behavior during bending (i.e., when loaded in flexure behond the elastic limit, micro-cracks occur and the fibers hold the cracks tightly closed, providing a ductile performance rather than a sudden or brittle failure) as shown in the following graph.
The ductility behavior observed during bending is characterized by a multiple cracks before the stress peaks, without localization and without the presence of any major cracks.
This super fine design matrix also produces a surface capable of intricate detail with unlimited surface textures, finishes and colors. DUCTALThe values above are for guidance only and cannot be used as technical design specifications.
It achieves this engineering feat by progressively absorbing the energy applied and efficiently dispersing it throughout the matrix.As a rule, a value of 0.3 is considered for calculations.Since the water to cement ratio is very low, Ductal® does not exhibit drying shrinkage.The ultra-high performance material that is Ductal® and its various components are protected by various patents and may not be used except pursuant to the terms of a license agreement with the patent holder.Ductal® exhibits excellent performance in compressions: It is 4 to 8 times higher than conventional concretes.
