The present invention relates to a novel cement composite having a matrix of silicate cement, wherein the matrix is filled with a natural crushed aggregate of arbitrary mineralogical composition and/or artificial aggregate based on expanded clays. The composite further contains gauging water and plasticizers, the amount of which is given by a required placeability and speed of placement of the cement composite into a formwork. The silicate cement is present in the amount of 300 to 620 kg/me3 of the composite and aggregate with fraction in the range of 0 to 8 is present in an amount of 150 to 350 kg/me3 of the composite, The cement composite of the present invention further contains coarsely crushed particles of natural and/or synthetic fabric and/or filling material of the plastic foam type in an amount of 80 to 150 kg/me3 of the composite. These crushed particles are of arbitrary form and thief minimal dimension is in mm units and the maximal dimension thereof is up to tens of mm. |
