Pumice is a pyroclastic rock that is abundantly available in Indonesia. Alkaline-activated pumice powder can be utilized as adsorbent for cationic contaminants in water environment owing to its mineralogical and chemical characteristics. These characteristics of pumice are site-specific. This study aims ...
Characteristics of Pumiceous Basalt and Its Application Prospects to Water Disposing. Conservation and Utilization of Mineral Resources, 2000, (2): 30-30. doi: 10.3969/j.issn.1001-0076.2000.02.008 [4] YAO Xulong, QIU Yu, ZHANG Yanbo, LIU Xiangxin, GAN Ze, CHENG Binbin. Experimental Study...
more determined by the sealer and amount of sealer applications. Pumicecrete will not meet building code for r-value requirements. It would add an extra stage to the wall building process in addition to needing plaster finishing. Covering up a rammed earth wall is a beautiful thing to cover u...
Weathering When a tree or other types of plants begin growing in the cracks of rocks, this may speed up the break down of the rock because of the pressure the roots may exert. Weathering Ice can also speed up the weathering process on rocks. If a rock has a crack that can fill up w...
The ability of AAM to utilize many industrial wastes such as slags, fly ashes, mineral wools, and natural materials such as laterite soil, marble/granite powder, basalt rock, will fulfill the requirement of a clean construction materials. Owing to the extensive use of AAM for different ...
The similarities in the pyroxene chemical compositions and the whole-rock characteristics between the two types of pumice indicate that both types of pumice are linked to the same magmatic system at depth. The pyroxenes crystallized from genetically related melts within a magmatic system that had ...
Micro-indentation experiments were performed to study the correlation, both qualitatively and quantitatively, between microstructural characteristics and mechanical properties of three types of aggregates, including basaltic crushed rock, vesicular volcanic rock composed of pumice and recycled concrete aggregates...
The cutting blade has a tool and rake angle of 蟺/3 and 蟺/9 rad respectively with blade tip made of WC-Co alloy. As a weak rock sample, a tuffaceous rock of pumiceous tuff including rhyolite sampled from Tochigi Prefecture, Japan was used. The result of the investigation shows that ...
We found various nucleating materials and these include rock fragments (fresh and altered), clay, pumice and sharks' teeth. In a majority of the cases, rock fragments are dominant in the core of the nodules and these conform to that of the seafloor basalts. The shape of the nuclei ...
The pyroclastic samples span the complete range of rock chemistries; however, compared to the lavas they are concentrated in the more evolved products and thus significantly enlarge the erupted volume of phonolitic and trachytic magma. The pumice and lava major- and trace-element trends generally...
