Abstract

A construction material, a hydrophobic, optionally multi-cellular, inorganic particulate material for use in the construction material, for example, to improve the crush strength and/or stability of the construction material, a method of making the construction material, constructions comprising the construction material, and a method of improving the stability of a construction material.

First claim

The invention claimed is:

1. A construction material comprising hydrophobic, inorganic particulate material, wherein the hydrophobic inorganic particulate material:
(i) is a multi-cellular inorganic particulate material or a spherical perlite comprising microspheres,
(ii) has a d 10 of at least about 50 μm, a d 50 of at least about 100 μm, and a d 90 of at least about 160 μm, and
(iii) has a crush strength of at least about 1500 kPa;
wherein a viscosity or density of the construction material does not change by more than about 20% over a 28 day period.

2. A construction material comprising hydrophobic, inorganic particulate material, wherein the hydrophobic inorganic particulate material:
(i) is a multi-cellular inorganic particulate material or a spherical perlite comprising microspheres,
(ii) has a d 10 of at least about 50 μm, a d 50 of at least about 100 μm, and a d 90 of at least about 160 μm, and
(iii) has a crush strength of at least about 1500 kPa;
wherein the construction material is a wall putty, tile adhesive, joint compound, or Exterior Thermal Insulating Composite Systems.

3. A construction material according to claim 2 , wherein the wall putty or tile adhesive are ready-to-use or ready-to-mix.

4. A method of making a construction material, the method comprising:
combining a hydrophobic, multi-cellular, inorganic particulate material with one or more further components of the construction material, and
forming the construction material therefrom,
wherein the hydrophobic, multi-cellular, inorganic particulate material has a crush strength of at least 1500 kPa, a d 10 of at least about 50 μm, a d 50 of at least about 100 μm, and a d 90 of at least about 160 μm.

5. A construction or building comprising a construction material comprising hydrophobic, inorganic particulate material, wherein the hydrophobic inorganic particulate material:
(i) is a multi-cellular inorganic particulate material or a spherical perlite comprising microspheres,
(ii) has a d 10 of at least about 50 μm, a d 50 of at least about 100 μm, and a d 90 of at least about 160 μm, and
(iii) has a crush strength of at least about 1500 kPa.

6. A method comprising incorporating a hydrophobic, multi-cellular, inorganic particulate material having a crush strength of at least 1500 kPa a d 10 of at least about 50 μm, a d 50 of at least about 100 μm, and a d 90 of at least about 160 μm in a construction or building.
