We still use the name pozzolana but it is applied to any volcanic material (pumice or volcanic ash), composed of fine volcanic glass. The Roman civil engineer Vitruvius (c.80–70BCE c.15 BCE) speaks of four types of pozzolana: black, white, grey, and red, all of which can be found in the volcanic areas of Italy, such as Naples.

True or False: Concrete can be made by mixing powdered

Typically it was mixed in a ratio of roughly 1:3 (hydrated lime: volcanic ash) for buildings and roughly 1:2 for underwater work. Now that you have a hydraulic cement (or mortar) you can mix it with an aggregate such as sand or gravel and create concrete. But the Roman

The UCS of felsic volcanic rock at the Cosmos nickel mine ranged from 135 to 252 MPa according to a test conducted at WASM by Machuca, Cordova and Villaescusa (2010). Binders

Crushed rock is transported from quarries by road or rail. The water used in the mixing of concrete is usually of a potable standard. Using non-drinking water or water of unknown purity risks the quality and workability of the concrete. The major natural resource is volcanic material whilst synthetic aggregates are produced by a thermal

Crushed aggregate is produced by crushing quarry rock, boulders, cobbles, or large-size gravel. Recycled concrete is a viable source of aggregate and has been satisfactorily used in granular subbases, soil-cement, and in new concrete. After harvesting, aggregate is processed: crushed, screened, and washed to obtain proper cleanliness and gradation.
