A related concrete externally-added water reducer comprises the following compositions: 110-115 parts by weight of melamine, 585-595 parts by weight of formaldehyde, 295-305 parts by weight of water, 250-260 parts by weight of sulfamic acid, 135-140 parts by weight of salicylic acid, and 140-145 parts by weight of solid potassium hydroxide. The concrete externally-added water reducer employing the above design is capable of avoiding cracking phenomenon during mixing of concrete.
