specimens exhibited very low rsistivity of approximately 13.2 ohm-cm or less when tested at ages between three and 28 days. These results illustrate that using carbon fibers in CLSM has a greater positive effect on lowering the resistivity above that normally achieved through the use of high-carbon fly ash alone. Electrical permeability decreased slightly when carbon fibers were used (Mixture CLSM-B).

Figure 5-10: Electrical permeability of High Carbon Fly Ash CLSM Mixture CLSM-A Dried vs. Saturated Specimens Measurements taken for saturated CLSM specimens produced significantly smaller resistivity values compared to the air-dried specimens when tested without carbon fibers (Mixture CLSM-A). For the dried specimens, the aging process affected the resistivity significantly; the older the specimens, the higher the resistivity. The aging process affected the dried specimens more than the saturated ones. This indicates adding moisture to the material in place improves its conductivity. For the mixture containing carbon fibers, Mixture CLSM-B, air-dried specimens also had a higher electrical resistivity, but the difference between saturated and air-dried specimens were much less. Typically the difference between air-dried and saturated specimens was one ohm-cm or less. This may be attributed to the conductivity of the carbon fibers used in the mixtures. Commonly-Used CLSM Mixtures We Energies has been testing and utilizing controlled low-strength materials containing fly ash for construction for over 15 years. Though several mixture proportions have been tried, a few mixtures are commonly used that are reexcavatable by ordinary methods. These mixtures usually are required to be self-leveling and essentially free from shrinkage after hardening. The mixtures that are most commonly used are designed to reach a state of hardening such that they can support the weight of a person in less than 24 hours. 151 We Energies Coal Combustion Products Utilization Handbook
