What is the composition of a clay/sand mixture used for flooring?

The composition of a clay/sand mixture for flooring that is commonly accepted is typically two parts clay to one part sand, making it a 2/3 clay and 1/3 sand mixture. This ratio is beneficial because clay provides the binding properties needed for strength and stability, while sand helps with drainage and prevents excessive shrinkage as the mixture dries.

This combination creates a material that is pliable yet firm enough, which is particularly valuable for flooring applications where durability and functionality are required. The clay helps retain moisture, making it easier to work with, while the sand contributes to the mixture's structural integrity, ensuring it can withstand foot traffic and other pressures in a flooring context.

Other ratios, such as a 50% clay and 50% sand mixture or a 3/4 clay and 1/4 sand composition, would not create the same balance of properties, possibly leading to issues such as cracking or insufficient strength in the final flooring product. Therefore, the two-thirds clay to one-third sand mixture is considered the optimal formulation for such applications.
