萘系减水剂PH值(5%水溶液):7-9,对钢筋无锈蚀作用。
The pH value (5% aqueous solution) of naphthalene series water reducer is 7-9, which has no corrosion effect on reinforcement.
水泥净浆流动度:≥200mm。
Fluidity of cement paste: ≥ 200 mm.
萘系减水剂含固量:粉剂≥92%;液体≥40%。
The solid content of naphthalene superplasticizer: powder ≥ 92%; liquid ≥ 40%.
硫酸钠含量:粉剂16%-19%;液体7%-9%。
Sodium sulfate content: powder 16% - 19%, liquid 7% - 9%.
萘系减水剂在保持坍落度不变时,减水率可达12%-20%。
The water reducing rate of naphthalene superplasticizer can reach 12% - 20% when the slump remains constant.
外观:粉剂褐黄色粉末。液体棕褐色粘稠液。
Appearance: powder brown yellow powder. Liquid brown viscous liquid.
萘系减水剂在相同水灰比情况下,可加大砼坍落度10cm以上。
Under the same water cement ratio, naphthalene water reducer can increase concrete slump by more than 10 cm.
对混凝土有显著的早强、增效效果,其强度提高幅度为15%-40%。
It has obvious early strength and synergistic effect on concrete, and its strength increase range is 15% - 40%.
萘系减水剂能改善和提高砼的物理力学性能,在保持强度相同时可节约水泥10%-20%。
Naphthalene superplasticizer can improve and improve the physical and mechanical properties of concrete, and can save 10% - 20% of cement at the same strength.
