Abstract
A cement-based material is formed from a mixture that includes cement in the range of about 40 to 90% by wet weight percent, a lightweight expanded aggregate in the range of about 10 to 60% by wet weight percent, a secondary material in the range of about 0.1 to 50% by wet weight percent, a reinforcement fiber in the range of about 1 to 20% by wet weight percent, a rheology modifying agent in the range of about 0.5 to 10% by wet weight percent, a retarder in the range of about 0.1 to 8% by wet weight percent, and water in the range of 10 to 60% of a total wet material weight.
Claims26
A lightweight thermal insulating cement-based material formed from a mixture comprising:
- a cement in the range of about 40 to 90% by wet weight percent;
- a secondary material comprising sand, silica fume, fumed silica, calcium carbonate, or a combination thereof in the range of about 0.1 to 50% by wet weight percent;
- a reinforcement fiber in the range of about 1 to 20% by wet weight percent;
- a rheology modifying agent in the range of about 0.5 to 10% by wet weight percent;
- a retarder in the range of about 0.1 to 8% by wet weight percent;
- and
- a water in the range of 10 to 60% of a total wet material weight.
A lightweight thermal insulating cement-based material formed from a mixture consisting essentially of:
- a cement in the range of about 40 to 90% by wet weight percent;
- a secondary material comprising sand, silica fume, fumed silica, calcium carbonate, or a combination thereof in the range of about 0.1 to 50% by wet weight percent;
- a reinforcement fiber in the range of about 1 to 20% by wet weight percent;
- a rheology modifying agent in the range of about 0.5 to 10% by wet weight percent;
- a retarder in the range of about 0.1 to 8% by wet weight percent;
- and
- a water in the range of 10 to 60% of a total wet material weight.
A method for manufacturing a lightweight thermal insulating cement-based material comprising:
- mixing a cement in the range of about 40 to 90% by wet weight percent, a secondary material comprising sand, silica fume, fumed silica, calcium carbonate, or a combination thereof in the range of about 0.1 to 50% by wet weight percent, a reinforcement fiber in the range of about 1 to 20% by wet weight percent, a rheology modifying agent in the range of about 0.5 to 10% by wet weight percent and a retarder in the range of about 0.1 to 8% by wet weight percent with water in the range of 10 to 60% of a total wet material weight;
- extruding the mixture through a die using an extruder;
- and
- allowing the extruded mixture to set.
