A method for producing a cement material with reduced development of self-induced cracking, the method comprising: adding to a concrete, mortar or cement mix to which water has been added, an amount of 0.05 to 1% by weight, based on the cementitious materials, of synthetic fiber bundles comprising 1
A method for producing a cement material with reduced development of self-induced cracking, the method comprising: adding to a concrete, mortar or cement mix to which water has been added, an amount of 0.05 to 1% by weight, based on the cementitious materials, of synthetic fiber bundles comprising 10-10,000 filaments per bundle, the filaments consisting essentially of a polyolefin, polyolefin derivative, a polyester or a mixture of the foregoing and having a length of 1-30 mm, a mean transverse dimension of 5-30 um and an aspect ratio of 100 to 1000, the filaments in each bundle being held together by a wetting agent, the wetting agent proving the individual filaments with a surface tension which allows them to become homogeneously dispersed in a concrete, mortar or paste mix with conventional mixing in conventional concrete mixing equipment, mixing the resultant mix for a period of at least 20 seconds to obtain a concrete, mortar or cement mix in which the individual filaments are homogeneously dispersed, and casting the concrete, mortar or paste mix in a configuration.
