US 7837788 B2Abstract
This invention is a fiber reinforced cement composition comprising the following raw materials: a hydraulic inorganic material, a siliceous material, and a woody reinforcement wherein the siliceous material is a mixture of an average particle size of not less than 15 um and not more than 50 um which is burned ash of coal and/or rhyolite and an average particle size of not less than 1 um and not more than 15 um which is burned ash of coal and/or rhyolite.
the siliceous material is a mixture of burned ash of coal and/or rhyolite having an average particle size of not less than 15 μm and not more than 50 μm and burned ash of coal and/or rhyolite having an average particle size of not less than 1 μm and not more than 15 μm, and
a woody reinforcement is needle-leaves-tree unbleached haft pulp and/or needle-leaves-tree bleached kraft pulp and used newspaper.
3. The fiber reinforced cement composition according to claim 1, wherein the woody reinforcement is a mixture of the needle-leaves-tree unbleached kraft pulp and/or the needle-leaves-tree bleached kraft pulp and the used newspaper in a ratio of the the needle-leaves-tree unbleached kraft pulp and/or the needle-leaves-tree bleached kraft pulp to the used newspaper in a range of from 1:1 to 4:1.
4. A fiber reinforced cement composition comprising the following raw materials:
not less than 25% by mass and not more than 45% by mass of the hydraulic inorganic material;
not less than 5% by mass and not more than 12% by mass of the woody reinforcement;
not less than 50% by mass and not more than 65% by mass of the siliceous material;
the siliceous material comprises burned ash of coal and/or rhyolite having an average particle size of not less than 1 μm and not more than 15 μm and burned ash of coal and/or rhyolite having an average particle size of not less than 15 μm and not more than 50 μm, the amount of the burned ash of coal and/or the rhyolite having the average particle size of not less than 1 μm and not more than 15 μm being not less than 25% by mass and not more than 75% by mass of the whole siliceous material, and
the woody reinforcement is a mixture of needle-leaves-tree unbleached kraft pulp and/or the needle-leaves-tree bleached kraft pulp and used newspaper in a ratio of the needle-leaves-tree unbleached kraft pulp and/or the needle-leaves-tree bleached kraft pulp to the used newspaper in a range of from 1:1 to 4:1,
the siliceous material comprises fly ash and/or pearlstone having an average particle size of not less than 15 μm and not more than 50 μm and fly ash and/or pearlstone having an average particle size of not less than 1 μm and not more than 15 μm, the amount of the fly ash and/or the pearlstone having the average particle size of not less than 1 μm and not more than 15 μm being not less than 25% by mass and not more than 75% by mass of the whole siliceous material.
6. The fiber reinforced cement product manufactured from the fiber reinforced cement composition according to claim 4.
7. The fiber reinforced cement product manufactured from the fiber reinforced cement composition according to claim 5.
8. A process for manufacturing the fiber reinforced cement product comprising the steps of:
dispersing in water a fiber reinforced cement composition comprising the following raw materials:
a woody reinforcement is needle-leaves-tree unbleached kraft pulp and/or needle-leaves-tree bleached kraft pulp and used newspaper, so as to give a slurry of the raw materials;
9. A process for manufacturing the fiber reinforced cement product comprising the steps of:
10. A process for manufacturing the fiber reinforced cement product comprising the steps of:
the siliceous material comprises fly ash and/or pearlstone having an average particle size of not less than 15 μm and not more than 50 μm and fly ash and/or pearlstone having an average particle size of not less than 1 μm and not more than 15 μm, the amount of the fly ash and/or the pearlstone having the average particle size of not less than 1 μm and not more than 15 μm being not less than 25% by mass and not more than 75% by mass of the whole siliceous material, so as to give a slurry of the raw materials;
The mark “◯” denotes no cracking and the mark “�” denotes generation of cracks.
