Hydrated lime (Ca(OH)2)- and reactive magnesia (MgO)-activated ground granulated blast-furnace slag (GGBS) have shown advantages in geotechnical applications compared with Portland cement (PC). To apply these two novel binders slurry form to field applications, the properties of their grouts need be investigated, which is objective this study. The heat hydration, bleeding, viscosity, setting be...

Abstract The article describes recent cases of tendon ruptures by corrosion and investigations carried out on some bridges in France. Several causes related to HDPE ducts have been identified such as damages during handling, threading tensioning strands, defective connection the duct anchorage, damage construction or operation, low quality material, etc. These rupture exclusively concern inject...

In the present research, optimum condition of grout consisting cement, fly ash, superplasticizer, and water was determined to produce most durable impermeable deep mixing columns (DMC) on silty soils. It is aimed reduce cost environmental pollution by using high-rate ash in grout. Superplasticizer additive used increase flow consistency ash. The design experiments made 5-parameter 4-level L16 o...

DISCUSSION: Rubblemound coastal structures contain voids between individual armor units. Structure voids maximize turbulent wave energy dissipation, but also allow passage of water and sediment. The volume of sediment passing through some jetties and terminal groins can be substantial, resulting in increased channel shoaling, higher maintenance costs, and significant loss of beach material.
