On the Mohs scale of mineral hardness, basalt scoresa six– meaning it's harder than platinum or iron. Is basalt basic or acidic? Acidic rock is rock that is either siliceous, having a high content of silica (SiO2), or rock with a low pH. The two definitions are not equivalent, e.g...
The dissolved species in the solution were determined and unreacted andreacted sample-surface chemical components involved or uninvolved in reaction were analyzed usingX-ray photoelectron spectroscopy (XPS). The results revealed two different mechanisms of dissolutionof basalt in acidic and basic solutions...

iii)In the weaker acidic or basic solution,because the dissolved ferric ion combines with OH~- to form Fe(OH)_3,which is sorbed on the sample surface,the content of iron on sample surface rises after the reaction;iv)Dissolved oxygen in solution participates in the redox of iron.According ...
Basic porousbasalt aggregates, are introduced to replace acidic silica aggregates with control of shape, size, and porosity for less denseparent basalt aggregate recycled PBR. A new foaming agent is introduced with a new non-traditional manufacturing processthat produces a "green" construction ...
Dissolution of Columbia River basalt under mildly acidic conditions as a function of temperature: experimental results rele- vant to the geological sequestration of carbon dioxide. Appl. Geochem. 24 (5), 980-987.H. T. Schaef, B. P. McGrail, Dissolution of Columbia River Basalt under mildly ...
with good heat resistance and fire resistance [26]. Ceramsite concrete is mainly used in the bearing structure as a wall material to meet the basic strength requirement. Good plasticity and impact resistant ability are also important however, and these requirements can be realized through adding rub...
