CONCEPT OF REINFORCED EARTH STRUCTURE DESIGN
Reinforced earth is a composite material formed by the friction between the earth and the reinforcement. By means of friction the soil transfers to the reinforcement the forces built up in the earth mass. The reinforcement thus develops tension and ...
EFFECT OF TRANSIT TIME ON READY MIX CONCRETE
Ready mix concrete is generally produced in large quantity and is transported to distant places for placement in structural elements. Sometimes the distance can be in many kilometers or miles. So, the effect of this transit times can reduce the ...
Behaviour of Concrete in Extreme Fire
