Sand-lime is made out of sand, lime and water (no additives). By high pressing the mixture and autoclaving afterwards a firm white building material is produced. The procedure is well-known as it first has been manufactured in Germany in 1894.
Other words for sand-lime bricks:
In the contrary to autoclaved aerated concrete no aluminium and gypsum is added, which prevents the chemical reaction (aerating) between the aluminium and the alkali in the lime and the cement.
