These properties can be improved by the incorporation of fibers. For this reason, asbestos fibers were conventionally used first. However, asbestos fibers are carcinogenic. Therefore, an alternative fibrous material was sought.

The aim is to present a fiber reinforced structural board as a component, and thus be able to treat it with conventional binders and yet to minimize the fiber proportion. Further, the structural plate should have high weather resistance. That is, it has been found that the known fiber reinforced structural plate often forms cracks under the influence of the surroundings (sun, rain, temperature change).

It contains 0.3 to 2% by weight of plastic fibers in combination with 2 to 5% by weight of elastomer, the fibers and the elastomer being distributed sufficiently homogeneously in the plate.

少なくなる。The addition of a small amount of the above-mentioned plastic fibers in combination with a very small amount of elastomer likewise surprisingly results in, for example, asbestos or fibrous fibers in terms of flexural tensile strength, breaking energy and weathering resistance. A fiber reinforced structural plate comparable to the known structural plate containing
This structural board is manufactured by the Hatchek method, and its fiber content is remarkably high. Using ordinary Portland cement as binder and ordinary sand as aggregate, 1
Bending tensile strength of 5 MPa or more and 10 J / mm 2 × 10
A breaking energy of -4 is obtained. Despite a small proportion of fibers and elastomers, the elastomers give rise to a kind of elasticity of the plate, which not only increases bending tensile strength and breaking energy as mentioned above, but also significantly improves weathering resistance.
The thermal stresses in the plate due to temperature changes are well absorbed due to the increasing elasticity of the material, resulting in significantly less crack formation.

均質な混合によつて容易に行うことができる。It is desirable to distribute the fibers and the elastomer as homogeneously as possible to obtain uniform physical properties over the entire cross section of the plate. This can easily be done by suitable method techniques, for example by intimate mixing of the components.
