Superplasticizer (SP) was used to increase workability.
As shown in Table 6, utilization of GWG increased workability of the fresh concrete.
However, experience shows that lime will react with many medium-, moderately fine- and fine-grained soils to produce decreased plasticity, increased workability, reduced swell, and increased strength.
So, more fine particles which can be packed between matrix powders would be a good method for decreasing viscosity, that is, increasing workability.
The increased workability due to the partial replacement enables a higher total conductive admixture content to be attained.
Douglas et al. (Douglas et al. 2006) reported the possibility of developing SCC containing class F fly ash, which lead to reducing super-plasticizer (SP) dosage, increase workability, and increase overall chloride permeability resistance.
This also has repercussion in the properties of concrete, which shows increased workability as well as poorer compressive strength and elastic modulus.
The most notable effect of lime on fine-grained soils is to produce decreased plasticity, increased workability, reduced swelling and shrinkage potential as well as increased strength [1, 6, 14, 16].
The practice of adding limited amounts of lead (generally less than 2%) to bronze to increase workability and fluidity began around 1000 b.C. and was fully developed by the Romans.
An effective technique to perform this task is to provide a foaming effect in mixing phase to increase workability by use of water containing additives such as zeolites.
