2. Shotcrete - Wikipedia

   en.wikipedia.org/wiki/Shotcrete

   Shotcrete, gunite (/ ˈ ɡ ʌ n aɪ t /), or sprayed concrete is concrete or mortar conveyed through a hose and pneumatically projected at high velocity onto a surface. This construction technique was invented by Carl Akeley and first used in 1907. [1]: 7 The concrete is typically reinforced by conventional steel rods, steel mesh, or fibers.

   Shotcrete (also known by the ... Carbonaide uses carbon dioxide in the curing phase of precast concrete production and has demonstrated up to 40% savings in cement ...

4. Steel fibre-reinforced shotcrete - Wikipedia

   en.wikipedia.org/wiki/Steel_fibre-reinforced...

   Traditional rebars are generally used to improve the tensile strength of the concrete in a particular direction, whereas steel fibers are useful for multidirectional reinforcement. This is one of the reasons why steel fiber reinforced (shotcrete form) concrete successfully replaced weldmesh in lining tunnels. Less labour is required.

5. Alkali–silica reaction - Wikipedia

   ASTM C1293: "Test Method for Concrete Aggregates by Determination of Length Change of Concrete Due to Alkali-Silica Reaction". It is a long-term confirmation test (1 or 2 years) at 38 °C in a water-saturated moist atmosphere (inside a thermostated oven) with concrete prisms containing the aggregates to be characterised mixed with a high-alkali ...

6. Accelerated curing - Wikipedia

   en.wikipedia.org/wiki/Accelerated_curing

   Accelerated curing is any method by which high early age strength is achieved in concrete.These techniques are especially useful in the prefabrication industry, wherein high early age strength enables the removal of the formwork within 24 hours, thereby reducing the cycle time, resulting in cost-saving benefits.
