A method for cleaning cement, mortar, concrete, calcium oxide, calcium hydroxide, or a laitance thereof from a surface which comprises. endstream Foaming gels, in particular those described above, generally form gels when they are mixed with water, that is to say that they increase the viscosity of the formulation without it being necessary to add a gelling agent. This is because it has been observed that the formulations in the gel form of alkanesulfonic acid(s) are very effective in the removal of cement-based contaminants, as described above, not only due to the gel itself, which makes possible a longer action of the acid active principle (the gel adheres for a longer time to the surfaces, in comparison with an aqueous formulation), but also exhibits an improved cleaning power, in comparison with other gel formulations. The present invention relates to the field of the cleaning of cement, mortar, concrete, laitances, lime and others. Because of Plastic Paving Blocks making moulds are clean now the production increases. "Back-Set" safely removes hardened concrete from a variety of difficult to clean surfaces.

Mention may be made, among solubilizing or hydrotropic agents which can be used in the formulations according to the invention, by way of example and without implied limitation, of sodium xylene- or cumenesulfonates. This chemical is an alternative to those chemicals which are non-biodegradable and running against the environment. The term derived products is understood to mean any solid product obtained from a mixture of water and cement and/or lime. 0000014819 00000 n Dissolves cured cement, concrete, mortar, grout, stucco Chemically Back-Set converts the positive ions in the hardened matrix into negative ions, which dissolves the cement into mud that can be rinsed away. 46 0 obj Alkanesulfonic acids exhibit the advantage, first, of being less corrosive than hydrochloric acid, of not generating chlorides, of being biodegradable and of not giving off toxic or nauseating products, and also of being less polluting than phosphoric acid, due to the phosphates discharged to the environment. As a general rule, the formulation comprises from 0.01% to 100% by weight of alkanesulfonic acid, more generally from 0.05% to 90% by weight, and in particular from 0.5% to 75% by weight of alkanesulfonic acid(s). The alkanesulfonic acids can also be used at high concentrations in order to increase their effectiveness, which concentrations can be 50%, 70% or indeed even 100% by weight, whereas the maximum concentration of hydrochloric acid can be at most only 37% due to the intrinsic chemical nature of this acid. To get off with this unneeded material Cement removing chemical ( a best Concrete Removing Chemical ). This amount can vary within wide limits according to the surfaces to be treated and the amount of cement, the temperature and the pressure of the formulation used, the desired duration of the removal method, and others. Concrete corresponds to mixtures of cement(s) and/or of mortar(s) with more or less large amounts of aggregates. In addition, the alkanesulfonic acids used in the present invention exhibit, in comparison with arylsulfonic acids, the advantage of generating a lower oxygen demand in effluent treatment plants (Chemical Oxygen Demand, COD) and consequently of making possible a higher concentration of organic discharges in said plants. This chemical is best for cleaning the concrete truck. The most commonly used acid in this application is hydrochloric acid, which dissolves lime, cement, mortar, concrete and other mixtures comprising cement and/or lime, in particular laitances of lime and of cement, and descales in a single operation, while optionally making it possible to dispense with any mechanical operation.
