Sredstvo za smanjenje vode

Sredstvo za smanjenje vode je dodatak koji može pomoći u smanjenju potrošnje vode i također poboljšati trajnost i funkcionalnost betona. The first sredstvo za smanjenje vode was used in the United Kingdom in the 1930s. Other countries like Japan and the United States have developed the technology of using this admixture.

Tipično, water reducing admixtures fall into three categories: low, srednji, and high. Low range reduces the amount of mixing water by more than twelve percent; medium range reduces it by more than fifty percent; and high range increases it by more than ten percent.
