Abstract
The present invention relates to admixtures production and to a method of application of the admixtures in cement and concrete technology. The method allows production of high-strength and high durable cement based systems, as well as cement systems with specially designed properties or cheap high-volume mineral admixture cements.
Claims49
A dry or semi- dry complex admixture for cement systems containing water reducer or high range water reducer in aqueous solution and active silicon dioxide based sorbent, wherein
- a sorbent is presented by fine alkali reactive non-crystalline silica dioxide based materials as fly ash rice husk ash, zeolite, silica fume, bentonite, activated kaolin, montmorillonite, diatomaceous earth;
- a sulphonated melamine, naphthalene formaldehyde, polyacrylate based admixtures, or their mix (including other admixtures) are used as high range water reducer;
- the mass ratio of reactive silica dioxide component to water reducer is ranged from about 5:1 to about 100:1.
The complex admixture composition and/or the mode of production in accordance with claims and/or including any references on Examples.
The high compressive strength of 70-180 MPa cement, dry mix, mortar and/or concrete composition and/or the mode of production in accordance with claims and/or including any references on Examples.
The cement, dry mix, mortar and/or concrete composition with high volume of 15-70% of mineral admixtures in cement content and/or the mode of production in accordance with claims and/or including any references on Examples.
The cement, dry mix, mortar and/or concrete composition and/or the mode of production in accordance with claims including any references on Examples.
