Title: Cement dissolving liquid
Inventor: UMEMOTO MASAO
IPC: C04B41/72
Filed: 1998-11-20
Abstract: PROBLEM TO BE SOLVED: To obtain a nontoxic, safe liquid with no concern about environmental pollution, capable of easily dissolving cement. SOLUTION: This liquid is such one as to be either a monocarboxylic acid, dicarboxylic acid, tricarboxylic acid, ketocarboxylic acid or hydroxy acid, or a mixture thereof; furthermore, this liquid is preferably incorporated with an alkyl acetoacetate. This liquid free from an alkyl acetoacetate is highly viscous, lacking in infiltrativity; however, this liquid incorporated with an alkyl acetoacetate has moderate infiltrativity and high dissolving ability. Lactic acid and/or glycolic acid is (are) liquid and dissolvable in an alkyl acetoacetate, therefore hard to be hydrolyzable, thus being preferable. Alternatively, a mixed liquid of an aqueous acid solution and an alkyl acetoacetate is gradually hydrolyzable, therefore the mixing operation is made pref. just before dissolving cement in the mixed liquid.
