摘要:
A method of producing a sheet-form material having an exposed solid surface comprises pre-mixing cement with at least one pozzolan to provide a cement/pozzolan mixture with a high pozzolan to cement ratio, adding to the cement/pozzolan mixture an aqueous solution comprised of water and a high range water reducer to produce a cement/pozzolan dough-like substance, adding and mixing a sufficient quantity of glass aggregate to said cement/pozzolan dough-like substance to produce a moldable composition, wherein, after adding and mixing in the glass aggregate, the pozzolan is present in the composition at about 5% to about 20% by weight, the cement is present in the composition at about 3% to about 20% by weight, and the aggregate glass is by weight a relatively high percentage of the composition. The moldable composition is placed into a mold and vibrated, and is allowed to cure.
摘要:
A cementitious composition for high density, low porosity sheet-form building materials having solid surfaces is comprised of cement, pozzolans, and a high percentage of fine and/or coarse glass aggregate, preferably present in an amount which by weight is at least 60% of the composition. The cement content is relatively low, preferably in the range of about 3% to 20% by weight, and the pozzolan to cement ratio is relatively high, preferably equal to or greater than unity, but which can suitably be in the range from 0.25 to 4. The composition preferably uses recycled glass and preferably has a high recycle content. The sheet-form material made in accordance with the invention can be used to provide exposed solid surfaces, for example, surfaces for shower walls and floors, counter-tops, table-tops, and the like, where low hydraulic permeability and high compressive and tensile strength are desired.
