Abstract
Method for preparing a concrete mortar which contains a fraction of inorganic grains having a diameter <500 μm, wherein the fraction containing the inorganic grains is added in the form of a granular material which contains the inorganic grains which, with the aid of a water-soluble polymer, are bound so as to form the granular material. As a result, a homogeneous mortar is obtained.
Claims15
A method for preparing a mortar useful in producing a product with improved mechanical properties which comprises a fine filler fraction of inorganic grains having a diameter of less than 500 μm,
- wherein said inorganic grains are quartz, blast furnace slags, limestone, sand or mixtures thereof,
- wherein the fine filler fraction of inorganic grains is added in the form of a granular material comprising the inorganic grains which, with the aid of a water-soluble polymer, are bound so as to form the granular material, and which granular material readily disintegrates in a water containing composition.
A method for preparing a mortar which comprises a fine filler fraction of inorganic grains having a diameter less than 500 μm,
- wherein said inorganic grains are quartz, blast furnace slags, limestone, sand or mixtures thereof,
- wherein the fine filler fraction of inorganic grains is added in the form of a granular material which comprises the inorganic grains which, with the aid of a water-soluble polymer, are bound so as to form the granular material, and which granular material readily disintegrates in a water containing composition, and
- wherein said inorganic grains comprise silicon oxide or calcium oxide, said method resulting in improved mechanical properties in a product formed from the mortar.
A method of preparing a concrete product with improved mechanical properties comprising:
- adding a granular material, that readily disintegrates in water, comprising,
- i) an inorganic filler having a grain diameter of less than 500 μm;
- and
- ii) a water-soluble polymer;
- to a mortar composition,
- wherein said inorganic filler is quartz, blast furnace slags, limestone, sand or mixtures thereof.
