• Effects of Shrinkage Reducing Agent and Expansive Additive ...

    This research is to study the effect of mortar mixed with shrinkage reducing agent (polyoxyalkylene alkyl ether type), expansive additive (CaO type), and fly ash (hereinafter “SRA,” “EX,” and “FA,” resp.). Moreover, steam curing was studied to improve the properties of mortar. The plastic shrinkage test was conducted by using the strain gauge embedded at x2009;cm from the ...

  • High Performance Concrete Additives

    Shrinkage reducing concrete mixture is typically comprised of polyoxyalkylene alkyl ether or similar composition. When such admixture is added to concrete during the batching stage, it can significantly reduce both the early and longterm drying shrinkage; reductions of 30 to 50% can be achieved.

  • Revealing the Mystery of Admixtures: WaterReducing and ...

    May 29, 2010· Waterreducing admixtures essentially neutralize surface charges on solid particles and cause all surfaces to carry like charges. Since particles with like charges repel each other, they reduce flocculation of the cement particles and allow for better dispersion. They also reduce the viscosity of the paste, resulting in a greater slump.
