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.

適用強度等級為C15~C60及以上的泵送或常態

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

混凝土工程。尤其適用配制高耐久、高流態、高保坍、高強及其對外觀質量要求高的混凝土工程。針對配制高流動性混凝土、自密實混凝土、清水飾面混凝土極其有利。

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.

普通減水劑宜用以日低氣溫5℃以上施工的混凝土。高能減水劑宜用以日低氣溫0℃以上施工的混凝土，并適用制備大流動性混凝土、高強混凝土及其蒸養混凝土。

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.

減水劑應選用質量穩定的產品，減水劑與水泥及摻和料之間應具備優良的相容性。當將不同功能的多種外加劑復合使用時，外加劑之間及其外加劑與水泥之間應有優良的適應性

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
