Definitions
- the invention relates to building materials, in particular concrete containing polyester fibers and additionally an oligoester.
- the properties of concrete such as compressive strength, tensile strength, flexural strength, elasticity, hardness, etc. can be modified by the mixing ratio, by the choice of starting materials, and by additives.
- To increase the strength of rod-like composites of the finest glass fibers or synthetic fibers such as fibers of polypropylene, polyethylene, polyoxymethylene, poly (ethylene terephthalate), poly (butylene terephthalate), polyamides, rayon etc added.
- adhesives, composites, rubber, rubber products, plastic materials, synthetic resins, etc. can be added to modify the properties of the fibers.
- the introduction of the fibrous additives to the building materials, in particular to concrete can be done by different methods.
- the fiber material can be packed in water-soluble materials and the packaging added to the concrete during the mixing process.
- the packaging material dissolves, the fiber material is distributed in the cement / water / aggregate mixture.
- dispersants such as condensation products of naphthalene sulfonate and formaldehyde or melamine sulfonate and formaldehyde
- a disadvantage is a high "slump loss", ie a loss of toughness and thus faster sedimentation, as well as a longer curing time of the concrete
- the incorporation of fibers into concrete can be improved if the fibers are treated with a glycol ether From IP 07-300773 it is known to incorporate aramid fibers in cement, wherein the aramid fibers are coated with a mixture of an anionically modified oligoester, a wax and a polysiloxane.
- the prior art methods for incorporation of fiber material into concrete do not fully solve the problems such as sedimentation, poor structural viscosity, clumping of the fiber material, and insufficient distribution of the fibers in the required amounts in the concrete mix.
- oligoesters to the liquid concrete mixture, consisting essentially of cement, aggregates (eg gravel, gravel, grit, sand), fiber material and optionally concrete admixtures, substantially favors the finely miscibility of the hydrophobic fibers in the aqueous mixture without To influence the structural viscosity of the concrete mix, the settling tendency, the processability and setting time of the concrete negatively. It is particularly advantageous to provide the polyester fibers with oligoesters prior to mixing with concrete, whereby the hydrophilicity of the fibers is improved and the affinity for the aqueous medium is increased.
