Anti-Slip Aluminum Oxide Additive | Heavy Duty Non-slip Floor
Garnet (1 grit size) is a low cost anti-slip that is not quite as hard or tough as aluminum oxide but a step up from silica sand in terms of durability and anti-slip safety. It comes in brown color so needs to be used in pigment coatings only. Aluminum Oxide (4 grit sizes and 3 colors) is a very tough mineral used for maximum anti-slip ...

How Does Contact with Aluminum Affect Concrete?
The question of the effect of concrete contact with aluminum drew some great responses. One respondent summed it up: "Aluminum and concrete don't mix, either in the plastic or hardened state." Aluminum reacts with the alkalis (OH) found in portland cement concrete. When these two chemicals are combined, the reaction produces hydrogen gas.
