XVIII. Structural and Building Materials Flashcards
applied to any crystalline rock composed predominantly of calcite, dolomite, or serpentine and takes a good polish.
Marble
a metamorphic limestone or dolostone, which is thoroughly recrystallized that much or all of the sedimentary structures and biologic interlocking are obliterated
Marble
light colored volcanic glasses, produced during the Pliocene and Quaternary volcanism.
Pumice and pumicite
a cellular, glassy rock formed by explosive volcanism
Pumice
also called volcanic ash or dust, has the same origin, chemical composition, and glassy texture but was blown into smaller particles during the eruptive process.
Pumicite
The largest deposit of Pumice and Pumicire in the Philippines is in _______.
Juban, Sorsogon
produced by crushing, screening and washing of andesite, basalt, limestone, marble, metavolcanic and other rock materials which meet certain requirements as to strength, soundness, and other specifications utilized in much the same way as sand and gravel
Rock aggregates
made from a mixture of water, cement, and both coarse and fine aggregate
Concrete
bitumen impregnations during the Miocene-Pliocene epoch in shale and sandstone in some parts of the islands including Villaba, Leyte
Rock Asphalt
The _____ rock asphalt is a lenticular body in a shale-sandstone series. The body is composed of interbedded, medium to coarse-grained sandstone with layers that show abundant fragments of limestone impregnated with tar and bitumen.
Villaba rock asphalt
What is the origin of tuff deposits and how has volcanic tuff (locally known as adobe) been historically used in the Philippines?
Tuff deposits are products of Quaternary explosive volcanism and exhibit variation in texture and color. In the Philippines, volcanic tuff (adobe) has been historically used as a dimension stone since the Spanish era, particularly in the construction of churches, fortifications, and houses.
