INCINERATED INDUSTRIAL WASTE UTILIZATION TECHNOLOGY
KALMATRON® KF-ASH is an additive to the concrete mixes containing over 50% of Industrial
Incinerated Waste (IIW) from the weight of cement. In order to utilize IIW with maximum benefits, that
concrete can be used for building of insulated structures. Also it is widely recommended for building on
remote territories for utilization of contaminated or low grade local building materials.
KALMATRON® KF-ASH provides maximum of cementitious value to concrete mix and prevents
leaching of unstable phases from IIW by encapsulation of insoluble impurities. It increases the field of IIW
utilization for chemically, biologically or organically contaminated raw materials.
Below is an example of 2 concrete mix designs for blocks production based on conventional coarse
sand and natural volcanic sand (Mexico). Volcanic sand is highly soluble in water that's why it has no
industrial value by itself. Applied KF-ASH additive provides encapsulation of volcanic sand preventing
from contact with water during of batch preparation. After hardening it results in "honeycombed" cement
rock matrix with numerous amount of voids functioning as thermal insulation of concrete structure.
SPECIAL APPLICATIONS
When IIW comes from metallurgical facilities it contains sub-ferro elements then performance of
KALMATRON® KF-ASH might be considered as providing the features of High Performance Concrete (HPC).
Encapsulation of micro metal elements coincides with their partial or complete oxidation into solutions of
KALMATRON® KF-ASH with given high chemical potential under the water to cement ratio of 0.42.
The petrography of that concrete may even exceed the modern standards of structural concrete or HPC.
Batch installation must be provided in accordance with "Application Instruction". Various types of IIW
may require different sequence of mixer loading and time to volumes ratios. Utilization of light weight
debris of wood, paper, plastics, and foams also needs adjustments of mixing techniques.
