Abstract:
It is shown that a highly reactive silica ash produced by incineration of rice hulls can be sucessfully used in mass concrete applications requireing high strengths without excessive rise in adiabatic temperature. In a concrete mixture when 30 percent rice hull ash by weight of the total cementing material was present, the 7-day and the 28-day compressive strengths were higher and the adiabatic temperature rise waas 18 F (10 C) lower than the control concrete.
