Types of Admixtures for Concrete
Concrete Admixtures that Control Cracking Reducing Drying or Shrinkage Cracking. Hydrated cement paste shrinks as it loses moisture from its extremely small pores. As the moisture is lost in these small pores, the surface tension of the remaining water tends to pull the pores together which results in a loss of volume over time.
