Sand sculptures on a beach are made with sand and water, and even ours tend to fall down after a day because the grains are circular and they roll off each other once dry. Professional sand sculptures can last for months. Sand artists use building sand that has angular grains and contains silt and clay, this binds the sand and keeps it together. Also, we often compact the sand to make it extra hardy.
