Water reducing agent is a kind of concrete admixture which can reduce the mixing water consumption under the condition of maintaining the concrete slump unchanged. Most of them are anionic surfactants, including lignin sulfonate, naphthalene sulfonate, formaldehyde polymer, etc. After adding concrete mixture, it can disperse cement particles, improve its workability, reduce unit water consumption and improve the fluidity of concrete mixture; Or reduce the amount of cement per unit to save cement.

适用強度等級为C15~C60及以上的泵送或常态

Suitable for pumping or normal operation with strength grade of C15 ~ C60 and above

混凝土工程。尤其适用配制高耐久、高流态、高保坍、高強及其对外观質量要求高的混凝土工程。针对配制高流动性混凝土、自密实混凝土、清水饰面混凝土极其有利。

Concrete works. It is especially suitable for preparing concrete projects with high durability, high flow state, high slump resistance, high strength and high requirements for appearance quality. It is very advantageous to prepare high fluidity concrete, self compacting concrete and fair faced concrete.

普通减水剂宜用以日低气温5℃以上施工的混凝土。高能减水剂宜用以日低气温0℃以上施工的混凝土，并适用制备大流动性混凝土、高強混凝土及其蒸养混凝土。

Ordinary water reducing agent should be used for concrete constructed with daily low air temperature above 5 ℃. High energy water reducing agent should be used for concrete constructed with daily low air temperature above 0 ℃, and is suitable for preparing high fluidity concrete, high strength concrete and steam curing concrete.

减水剂应选用質量稳定的产品，减水剂与水泥及掺和料之间应具备优良的相容性。当将不同功能的多种外加剂复合使用时，外加剂之间及其外加剂与水泥之间应有优良的适应性

Water reducing agent shall be products with stable quality, and there shall be excellent compatibility between water reducing agent and cement and admixture. When multiple admixtures with different functions are used in combination, there shall be excellent adaptability between admixtures and between admixtures and cement
