Hydrous calcium silicates and method of preparation

Claim 1

AN INTEGRATED POROUS HYDROUS CALCIUM SILICATE PRODUCT, CONSISTING ESSENTIALLY OF TWO CRYSTALLINE STRUCTURES, ONE OF SAID CRYSTALLINE STRUCTURES HAVING THE COMPOSITION 4CAO.5SIO2.5H2O, AND THE OTHER CRYSTALLINE STRUCTURE HAVING THE COMPOSITION 5CAO.5SIO2.H2O BEING PRESENT AND COMBINED WITH SAID FIRST MEMTIONED STRUCTURE, THE SAID CRYSTALLINE STRUCTURES BEING CONTINUOUSLY INTEGRATED WITH EACH OTHER IN RANDOM DISPERSION, AND FORMING A THREE-DIMENSIONAL NETWORK INTERSPERSED WITH VOIDS, THE AGGREGATE VOLUME OF THE VOIDS BEING IN EXCESS OF THAT OF THE CRYSTALS.

Claim 3

THE METHOD OF FORMING AN INTEGRATED HYDROUS CALCIUM SILICATE PRODUCT WHICH COMPRISES PROVIDING AN AQUEOUS SLURRY CONSISTING ESSENTIALLY OF SOLIDS IN THE FORM OF REACTIVE LIME, REACTIVE SILICA AND A SUSPENSION AGENT FORSAID SOLIDS IN THE FORM OF HIGHLY SPICULATED FIBERS, WHEREIN THE INITIAL MOLAR RATIO OF LIME TO SILICA IS AT LEAST 0.8 BUT LESS THAN 1.0, THE AMOUNT OF WATER IN THE MIXTURE BEING WITHIN THE RANGE OF ABOUT 7.0 TO .75 TIMES THE AGGREGATE WEIGHT OF THE SOLIDS, SUBJECTING SAID SLURRY TO A TEMPERATURE AND PRESSURE IN EXCESS OF 175* C. AND 130 P. S. I. ABS, RESPECTIVELY, MAINTAINING SAID SLURRY AT A TEMPERATURE AND FOR A PERIOD OF TIME NECESSARY TO EFFECT SUBSTANTIALLY QUANTITATIVE REACTION BETWEEN THE REACTIVE LIME AND SILICA COMPONENTS, THEREBY TO PRODUCE A CRYSTALLINE END PRODUCT CONTAINING A CRYSTALLINE COMPOUND IN INTEGRATED FORM, THE PERCENTAGE OF SUCH COMPOUND PRESENT IN SAID END PRODUCT BEING DEPENDENT UPON THE INITIAL MOLAR RATIO OF LIME TO SILICA IN THE SLURRY, THE ONE SAID CRYSTALLINE COMPOUND HAVING THE COMPOSITION 4CAO.5SIO2.5H2O AND DRYING SAID PRODUCT.

Claim 4

THE METHOD OF FORMING AN INTEGRATED HYDROUS CALCIUM SILICATE PRODUCT WHICH COMPRISES PROVIDING AN AQUEOUS SLURRY CONSISTING ESSENTIALLY OF SOLIDS IN THE FORM OF REACTIVE LIME, REACTIVE SILICA AND A SUSPENSION AGENT FORSAID SOLIDS IN THE FORM OF HIGHLY SPICULATED FIBERS, WHEREIN THE INITIAL MOLAR RATIO OF LIME TO SILICA IS AT LEAST 0.8 BUT LESS THAN 1.0, THE AMOUNT OF WATER IN THE MIXTURE BEING WITHIN THE RANGE OF ABOUT 7.0 TO .75 TIMES THE AGGREGATE WEIGHT OF THE SOLIDS, SUBJECTING SAID SLURRY TO A TEMPERATURE AND PRESSURE IN EXCESS OF 175* C. AND 130 P. S. I. ABS, RESPECTIVELY, MAINTAINING SAID SLURRY AT A TEMPERATURE AND FOR A PERIOD OF TIME NECESSARY TO EFFECT SUBSTANTIALLY QUANTITATIVE REACTION BETWEEN THE REACTIVE LIME AND SILICA COMPONENTS, THEREBY TO PRODUCE A CRYSTALLINE END PRODUCT CONTAINING A CRYSTALLINE COMPOUND IN INTEGRATED FORM, THE PERCENTAGE OF SUCH COMPOUND PRESENT IN SAID END PRODUCT BEING DEPENDENT UPON THE INITIAL MOLAR RATIO OF LIME TO SILICA IN THE SLURRY, THE ONE SAID CRYSTALLINE COMPOUND HAVING THE COMPOSITION 4CAO.5SIO2.5H2O AND DRYING SAID PRODUCT.
