Preperation of Foam Concrete with HuNan Iron Ore Tailings

Abstract:

The main mineral component of HuNan ChenZhou iron ore tailings is quartz, fluorite, calcite, pyroxene, etc. The average particle size of the tailings is 0.15mm, -200 for the purpose of 6.30 percent. Using the tailings as the aggregate, 42.5R ordinary cement as the gelled material, HTD-1 as foaming agent and other addition agent for prepared foam concrete, m(cement):m(tailing):m(additive):m(vesicant)=1:(1~2.3):(0.02~0.2):(0.005~0.09). At the standard curing conditions its performance fully meet the requirements of B09 density range in JC/T 1062-2007 standard and the strength range for the A5.0.
