Abstract
A water repellent sand mixture includes at least water repellent sand and cement at a weight ratio of 2% or more and 5% or less relative to the water repellent sand. The mixture achieves condensation between the water repellent sand particles by the hydration reaction of the cement, which improves dynamic stability. The mixture can be kept in a block shape due to such improved dynamic stability, water repellency, and less slidable surfaces of the sand particles.
