DUCTAL is fiber-reinforced and has tensile strength, unlike conventional concrete.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." The values above are for guidance only and cannot be used as technical design specifications.They depend on the product characteristics, experimentation method, raw materials, formulas, manufacturing procedures and equipment used; all of which may vary.

The loading applied was between 10 and 90% of the elastic limit.In addition, reauthorizations including the National Defense Authorization Act and the National Flood Insurance Program need to be addressed by the end of the calendar year.Municipal street and road construction offers enormous opportunities for ready mixed concrete producers and local promotion partners.An endogenous shrinkage is observed (300 to 400 μm/m), but when heat treatment is applied, shrinkage is complete by the end of the treatment and there is no subsequent residual shrinkage, as shown in the figure below.Ductal® with metallic fibers contains 2% by volume of metallic fibers, or more than 50 million metallic fibers per cubic meter.
