They can be used for concrete.
Granite is commonly used in building construction and countertops due to its durability and aesthetic appeal. Basalt is often used as a construction material for roads and railway ballast because of its strength and resistance to weathering. Pumice is used in abrasives, polishes, and horticulture as a lightweight, abrasive material.
That depends on the chemistry of magma the volcano erupts - Basalt, andesite, rhyolite etc. but Generically the rock coming out of a volcano is called lava rock (pahoehoe or aa) but one can also get pumice or ignimbrites.
They are usually about the same density as non-volcanic rocks. The one exception is pumice, which is so full of holes that it is less dense than water.
There are several different rocks that are formed in this manner, depending upon the makeup of the lava. You are probably looking for one of these three answers: pumice scoria vesicular basalt
Pumice is a type of volcanic glass that contains holes caused by pockets of gas trapped during its formation. These holes give pumice a lightweight and porous texture, making it commonly used in beauty products and as an abrasive.

Pumice makes it a good abrasive for cleaning Nd polishing. Native Americans used obsidian to make Sharp tools. Egyptians used granite for statues. They also used other igneous rocks to build fortresses.
Crushed basalt can be used for asphalt.
Dried lava would be an igneous rock such as basalt, pumice, or granite! Most people have these types of rocks at home.

Basalt (solid)--188 pounds per cubic foot.

Pumice is classified as a felsic, glassy, highly vesicular, extrusive igneous rock.
one. Pumice.
Pumice is far less dense than galena. Galena is one of the densest minerals.
