Clay dosage and water/cement ratio of clay-cement grout for optimal engineering performance

摘要: Abstract Clay-cement grout is widely used in grouting engineering, but the varied field demands are often difficult to satisfy since properties of affected by multiple factors and cannot be simply predicted. This Note presents an experimental study investigate effect clay dosage water/cement ratios on performance clay-cement grout. Twenty batches samples were designed varying from 0.5 2 dosages 5% 45% which ranges commonly engineering practice. The results showed that optimal was highly dependent ratio. In general, higher lower ratio improved stability led permeability a poor terms fluidity strength. A methodology proposed for determining optimum fulfill various demands. applicability economic benefits presented method evaluated detailed case also demonstrated effectiveness framework determination ingredients
