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.
Granite is commonly used in construction and as a durable material for countertops and flooring due to its strength and aesthetic appeal. Basalt, being dense and durable, is often used in road base, construction aggregate, and as a decorative stone in landscaping. Pumice, with its lightweight and abrasive properties, is used in beauty products for exfoliation, as well as in lightweight concrete and insulation materials.
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 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.
