Super Mud slurries stabilize excavations, maintain cleanliness of the hole, and promote stronger load capacity at the same time Super Mud slurries simplify the process of mixing, excavating and concrete placement. The slurries are renewable and recyclable. Worldwide, super mud has replaced Bentonite slurries. Super Mud is a highly concentrated synthetic polyacrylamide polymer. Super Mud slurries achieves their largest molecular structures by the linking of simple repeating units called monomers. When mixed with water, the water molecules attach themselves to polymer chain forcing the polymer structure to swell and stiffen.
Viscosity increases due to the enlargement and shear strength of the hydrated polymer molecules. Super Mud polymer slurries are anionic in nature; meaning they have a negative ionic charge. Most soil particles have positive charge on their outside corners. Within the column of slurry, the negative charged polymer molecules encapsulate and bridge between positively charged soil particles. The clustered soil particles are large and quickly settle to the bottom of the excavation. The anionic polymer chain tend to satisfy the positive charged edges of the soil particles, forming a polymeric barrier against migration of water into the matrix of soil being excavated.
