The Influence of Water Glass on the Technological Parameters of Shotcrete
Shotcrete used in tunneling must follow a clearly defined early strength development in order to comply with stresses from rock deformations and drilling and blasting. Accelerators are...

Advances in Dry Shotcrete Technology by Means of Microsilica
During the last decade microsilica has been increasingly used to improve both wet and dry mix shotcrete. In the traditional dry process microsilica is blended in the dry mixture. Since...

ASTM C666 (A) Freeze-Thaw Durability of Air-Entrained Wet- and Dry-Mix Shotcrete
In order to assess the freeze-thaw durability of shotcrete, six samples of dry-mix shotcrete and one sample of wet-mix shotcrete were mixed outdoors at Hydro-Quebec's research institute...

Remedial Grouting at Calero Dam
This paper describes the design and construction of a remedial grout curtain to resolve a long-standing seepage condition at Calero Dam, located at the south end of the highly-populated...

Development of High Performnance Shotcrete (Theoretical Considerations)
This paper presents some theoretical considerations for studies on high performance wet-mix shotcrete. A new laboratory shotcrete pump and rheometer are being developed to study the effects...

Silica Fume Concrete: A Solution to Steel Reinforcement Corrosion in Concrete
This paper discusses the utilization of silica fume concrete admixture to prevent reinforcing steel corrosion. The mechanism of steel corrosion in salt impregnated concrete is described,...
