With the help of the Chinese Ministry of Education, a meeting was recently held to verify the condensed stone, an artificial stone-like matter made of mini crystal gluing materials, and the associated clean preparation technique. Experts agreed that the original findings has led to the establishment of a theoretical system for simulating rock formation process using mini crystal materials, and the project has developed a proprietary technical system for clean production of such materials.
The socalled ?°condensed stone?± is a silicon-aluminum based gluing material, made of industrial wastes, including metal dregs, coal ashes, gangue, red mud, and other solid wastes. High performance building materials such as this can be produced under normal temperature and pressure, simulating the rock forming process after a volcanic eruption, and using small quantity of rock forming agent. It is deemed as ?°green cement?± as it consumes no natural resources, and emits no ?°three wastes?±.
Comparing with overseas artificial stone making technologies, the condensed stone is made of innovative technologies different from the former. Raw materials: overseas technology uses baked kaolin earth, while the condensed stone using wastes dregs, coal ash, and red mud discharged from aluminum electrolyzing; and manufacturing techniques: a one-way approach is used in overseas technology, namely the baked kaolin earth is grinded dry together with the activating agent, while in the condensed stone case raw materials and the activating agent are grinded wet separately, needing no baking. The final product is simply the mix of the two, using the socalled two-way approach. |
