NBRRI CLAY POZZOLANA

Pozzolana cement is an innovative cement supplement used in the production of concrete and mortar. NBRRI pozzolana cement is produced from high kaolin clay by calcination at moderate temperatures (65 deg. C – 80 deg C.)

BENEFIT OF NBRRI CLAY POZZOLANA

  • Improved workability of mortar and concrete
  • Reduced heat of hydration, bleeding and segregation of concrete
  • Minimizes the effect of sulphate attack in concrete and mortar
  • Reduced effect of alkali aggregates reactivity
  • Reduced cost of housing by 35% from cost associated with cement

Test carried out on the NBRRI pozzolana showed that 30 – 45% partial replacement of cement can be obtained

NBRRI has two (2) pozzolana plant located in Nigeria; Ota, Ogun and Bokkos, Plateau State
