  • Chemical Admixtures

    Retarding admixtures, which slow the setting rate of concrete, are used to counteract the accelerating effect of hot weather on concrete setting. High temperatures often cause an increased rate of hardening which makes placing and finishing difficult. Retarders keep concrete workable during placement and delay the initial set of concrete.

  • Viscosity Modifying Admixtures| Concrete Construction Magazine

    Jun 28, 2016· Under shear or handling (mixing, pumping, finishing, extrusion), the VMA polymer chains become aligned, disrupting the network, and creating a condition of low viscosity or enhanced flow performance. When shear forces are no longer applied, the VMA polymer chains realign, rebuild the network, and a higher, stabilizing viscosity is restored.
