Sandcrete - Wikipedia

Sandcrete is usually used as hollow rectangular blocks similar to concrete masonry units, often 45 centimetres (18 in) wide, 15 centimetres (5.9 in) thick, and 30 centimetres (12 in) with hollows that run from top to bottom and occupy around one third of the volume of the block. The blocks are joined together with mortar.
