Gypsum concrete can be normal weight (with an average density 1800–2500 kg/m 3), lightweight (500–1800 kg/m 3) and extralightweight (less than 500 kg/m 3). For normalweight, concrete coarse aggregates (crushed stone and gravel) and fine aggregates (natural sand, screenings of crushed rocks and industrial wastes—slag, fly ash) are used.
