RICE HUSK ASH
Global Recycling

• Rice Husk Ash (RHA) used as partial replacement
  for Ordinary Portland Cement (OPC) in concrete.
• Compressive Strength test was carried out on
  hardened 150mm concrete cubes after at 1, 3, 7,
  28, 45 56 days curing in water
• The compressive strength of the hardened concrete
  also decreased with increasing OPC replacement
  with RHA.

INTRODUCTION
Global Recycling

• Rice husk is an agricultural waste product which
  is produced in about millions of tons.
  Approximately, for 100 Kg of rice, 20 Kg of rice
  husk are obtained. Rice husks contain organic
  substances and 20 of inorganic material.
• Physical characteristics and chemical composition
  of mineral admixtures can be fulfilled by burning
  Rice husk into rice ash.
• Combustion of rice husk at controlled temperature
  produces RHA that has amorphous silica content
  and large surface area.

Value of Rice Husk Ash (RHA)
Global Recycling
Rice Husk Ash (RHA) is a good pozzolan proved by
numerous researchers. During mass concrete, as
compared to OPC concrete, RHA is very effective
in reducing the temperature of mass concrete. The
use of Rice Husk Ash as partial replacement for
Ordinary Portland Cement in concrete. Compressive
strength of the concrete at different level of
replacement of RHA with OPC is determined.
