Abstract
Official abstract text for this publication.
The present invention comprises a product. The product comprises a first mineral in particulate form and having a first pozzolanic reactivity and a second mineral in particulate form and having a second pozzolanic reactivity greater than the first reactivity, wherein the surface of at least some of the particles of the first mineral is at least partially covered with particles of the second mineral. A method of making the composition of the present invention is also disclosed.
First claim
Opening claim text (preview).
What is claimed is: 1 . A product comprising: a first mineral in particulate form and having a first pozzolanic reactivity; and a second mineral in particulate form and having a second pozzolanic reactivity greater than the first mineral pozzolanic reactivity, wherein particles of the second mineral are disposed on the surface of the first mineral. 2 . The product of claim 1 further comprising a hydraulic cement. 3 . The product of claim 2 , wherein the hydraulic cement if portland cement. 4 . The product of claim 1 , wherein the first mineral is an igneous rock. 5 . The product of claim 1 , wherein the first mineral is olivine, pyroxene, magnetite, quartz, hornblende, biotite, hypersthene, feldspathoids, plagioclase, calcite, crystals or mixtures thereof. 6 . The product of claim 1 , wherein the second mineral is a microsilica, a nanosilica or an alumionosilicate. 7 . The product of claim 1 , wherein the second mineral is silica fume, Metakaolin or an aluminosilicate clay. 8 . The product of claim 1 , wherein the first mineral has a reactivity of less than 100% as measured by ASTM C-618. 9 . The product of claim 1 , wherein the second mineral has a reactivity of greater than 100% as measured by ASTM C-618.
