RXSOL Chemical Company developed this molecular cement dissolver as an alternative to using hazardous acids for concrete removal. Back-Set is a one-of-a-kind formula. It uses an active ingredient found in molasses syrup, and is completely biodegradable.
RXSOL turned this vulnerability into an opportunity. “Back-Set” safely removes hardened concrete from a variety of difficult to clean surfaces. It break down the ionic bond in portland cement, releasing the cement from any surface to which it has adhered.
Chemically speaking, Back-Set converts the positive ions in the hardened matrix into negative ions, which dissolves the cement into mud that can be rinsed away. Because it works chemically, rather than mechanically, Back-Set may be used to remove cured concrete, mortar, grout, and stucco from virtually any surface without harm.
Dissolves the cement into MUD
USING PROCEDURE ::::
The hardened concrete is saturated with Back-Set, either with a brush or by spraying. After 15-20 minutes, the area is again saturated with the chemical. The concrete typically begins to soften in 20-30 minutes, and can be rinsed off with water.
The decomposition of the concrete depends on the porosity of the cement paste and solubility materials of the concrete. Insoluble may precipitate in the voids and can slow down the reaction due to their low solubility, inhibit the attack by blocking the pathways within the concrete such as interconnected cracks, voids and porosity. Flushing with water time to time in between reaction is very damaging to concrete as it accelerate dissolving and reaction attack towards deposition.
