Water-Reducer

Definition / 释义

water-reducer(减水剂):一种用于混凝土/砂浆的化学外加剂,在保持或提高工作性(流动性)的同时,减少拌合用水量,从而有助于提高强度、耐久性并降低水胶比。也常见更具体的说法如 water-reducing admixture(减水型外加剂)。

Pronunciation / 发音

Etymology / 词源

water(水) + reducer(减少者/降低者) 组合而成的复合名词,属于工程与材料领域的功能性命名:字面意思就是“用来减少用水量的东西”,在混凝土技术语境中固定指“减水剂/减水型外加剂”。

Examples / 例句

The contractor added a water-reducer to improve the mix.
承包商加入了减水剂来改善拌合物性能。

By using a water-reducer, the concrete achieved the same slump with less water, which helped lower the water-cement ratio and increase strength.
使用减水剂后,混凝土在更少用水量下仍达到相同坍落度,从而降低了水灰比并提高了强度。
