Hydration and Strength Behavior of Sugarcane-Baggase Ash Concrete Using Electrical Resistivity Measurement

摘要

Electrical resistivity method was adopted in monitoring the hydration of concrete containing different percentage of baggase ash. It has been discovered that the bulk electrical resistivity is a function of the solution electrical resistivity and porosity. Two model components were suggested where the solution resistivity was dominated by bulk resistivity at early age then by porosity at later age. The result found that the pore discontinuity occurs faster with increasing baggase ash quantity up to 20% then started declining meaning that 20% is within the optimum range of the baggase ash quantity to be used and this is similar to the results obtained from compressive strength, setting time tests.
