    摘要: A pozzolan admixture composition suitable for use in portland cement mixtures and mix designs that, when combined with; portland cement, sand and/or aggregate, and water, are used to prepare cementitious products. The admixture contains ultra-fine fly ash, calcined kaolin, fused silica, and cellulose ether derivative. A pozzolan-modified portland cement composition containing the present invention's composition inter-ground or inter-blended with a portland cement. The pozzolan-modified portland cement contains portland cement, ultra-fine fly ash, calcined kaolin, fused silica, and a cellulose ether derivative. An admixture, additive, or addition, based on the present invention's composition, inter-ground or inter-blended into portland cement to create such pozzolan-modified portland cements. An admixture, additive, or addition, based on the present invention, that is subsequently added or mixed into a read-mix or wet mixture of portland cement, sand and/or aggregate, and water, containing ultra-fine fly ash, calcined kaolin, fused silica, and cellulose ether derivative.

    摘要: A mechanically activated pozzolan prepared from granitic quarry fines. Quarry fines are milled by a high-energy milling process to convert the essentially inert raw granitic fines into a chemically reactive state. When added to a portland cement mortar mixture, mechanically activated fines combined with calcium hydroxide to improve the strength of the cured mortar compared to a similar mixture prepared with raw fines. Mortars prepared with mechanically activated granitic fines typically show strength values comparable to or exceeding similar mortars made using fly ash as a pozzolan. In some instances, the strength of a mortar prepared with mechanically activated granitic quarry fines exceeded a mortar prepared using 100% portland cement as the cementitious component.

    摘要: One kind of super high strength concrete, by adding some zeolites to cement, in order to attain the objective of shortening the time of hydration of cement, so that the concrete shows higher initial compressive strength. Zeolites and cement can undergo the Pozzolanic reaction which results in less void content and higher final compressive strength, so we can get super high strength concrete.
