PROBLEM TO BE SOLVED: To provide: a dust-proof hydraulic composition product which is obtained by premixing a hydraulic composition, fine aggregates, and diethylene glycol and/or triethylene glycol, and from which dust discharge when work is done can be suppressed even when impact is imparted to the dust-proof hydraulic composition product from outside due to agitation or falling; and a method for producing the premixed product of the dust-proof hydraulic composition product.SOLUTION: The premixed product of dust-free hydraulic composition is a premixed product of hydraulic composition containing a hydraulic composition, fine aggregates, and a polyalkylene glycol having a molecular weight of 1,000 or less. The product is a mixture obtained by concurrently mixing and homogenizing the hydraulic composition, fine aggregates, and a polyalkylene glycol having a molecular weight of 1,000 or less, or a mixture obtained by mixing and homogenizing a polyalkylene glycol having a molecular weight of 1,000 or less in a mixture of a hydraulic composition and fine aggregates. |
