A Preliminary Laboratory Evaluation of Artificial Aggregates from Alkali-Activated Basalt Powder

چکیده
The widespread use of natural aggregates is one the main causes depletion resources, as are constituents several construction materials. Alternatively, it is, today, proven to be feasible mining tailings, either or recycled materials, produce artificial through specific processes. A possible way aggregate alkali activation powdered material in a process called geopolymerization. This study proposes basalt powder and two different metakaolins precursors for production an alkali-activated aggregate, with shape size achieved by using 3D-printed molds. experimental were evaluated traditional tests aggregates, such resistance compression, density abrasion fragmentation. Furthermore, was chemically analyzed order evaluate geopolymerization promoted adopted metakaolins. physical showed that do not perform well terms wear fragmentation, which can improved. However, they revealed promising results skid, polishing micro-texture.

Investigation on the effect of slag and limestone powder addition in alkali activated metakaolin
Alkali activated material has recently attracted great attention as an environmentally friendly building material. Generally, it exhibits higher mechanical properties and better durability when compared with Portland cement based materials. In this article, mixed alkali activated systems consisting of N-A-S-H and C-A-S-H hydrated gels were produced, using metakaolin as a dominated starting mate...
متن کاملViscosity measurements of subliquidus magmas: Alkali olivine basalt from the Higashi-Matsuura district, Southwest Japan
We carried out viscosity measurements and sampling of a crystal suspension derived from alkali olivine basalt from the Matsuura district, SW Japan, at subliquidus temperatures from 1230 °C to 1140 °C under 1 atm with NNO oxygen buffered conditions. Viscosity increased from 31 to 1235 Pa s with a decrease in temperature from 1230 to 1140 °C. On cooling, olivine first appeared at 1210 °C, followe...

متن کاملTumor-derived activated cells: preliminary laboratory and clinical results.
It is well known that T lymphocytes can mediate significant anti-tumor responses. A limiting factor has always been the ability to expand T cells, whether from the peripheral blood, spleen, or tumor. The recent availability of recombinant interleukin-2 (r-IL2) has demonstrated the feasibility of expanding T cells and the clinical efficacy of these cells as anti-tumor effectors in murine models....
