reinforced concrete for pavement applications. However, Merta et al., (2011) studied wheat straw reinforced concrete for building material applications. They concluded that there is an increase (i.e. 2%) in fracture energy of wheat straw reinforced concrete. Thus, wheat straw reinforced concrete needs to be investigated for rigid pavements.

reinforced concrete, Ultra-high performance concrete, Reactive powder concrete. The most common and well researched material is fibre reinforced concrete using different fibers. The concept of using fibers is to enhance the tensile behaviour of the concrete by bridging the cracks and improving the load carrying capacity of the structural members.

Reinforced concrete jacketing is a traditional and one of the most common methods to retrofit and/or repair reinforced concrete columns. The additional cross-section area helps the column transfer more load while providing additional confinement. Reinforced concrete jackets

The parent project aims to relate design and assessment for a broad spectrum of building layouts and heights, for both reinforced concrete and structural steel lateral resisting systems.

There is a number of ways to prevent damage of the reinforced concrete foundations. The paper displays some of the protection methods of reinforced concrete foundations from the aggressive impact of the environment. They are divided into: protection of reinforced concrete foundations from the physical, biological and chemical impacts [1-4]. 2.

In thin reinforced concrete walls, the same problem happens as in other densely rein-forced concrete structures. Due to a tight reinforcement net, aggregates are separated from cement and get stuck between rebars. Ultimately it leads to unequal distribution of concrete mass. In reinforced concrete walls openings have dense reinforcement. (1.)

In general, techniques used in conventional reinforced concrete construction need not he changed when bamboo is to be used for reinforcement. 3.1 Concrete Mix Proportions The same mix designs can be used as would normally be used with steel reinforced concrete. Concrete slump should be as low as workability will allow.

In reinforced concrete structures-1, it was explained how all components of a reinforced concrete section contribute to its shear resistance. (Cracked, Uncracked concrete section and the reinforcement provide for flexure) However, the torsional resistance of the section is provided almost entirely by the outer portion of the section.

The simulated defects were embedded inside the reinforced concrete foundation slab and the concrete wall. Types of simulated defects embedded in the base slab and the wall were:

The use of reinforced concrete walls in building construction is virtually unavoidable due to their efficiency and cost-effectiveness. As a load-bearing element, they are often used in combination with reinforced-concrete frames and masonry walls, as well as prestressed concrete elements. Approximate response of such mixed bearing

3 REINFORCED CONCRETE SUSTAINABILITY As building material reinforced concrete can be hardly considered a sustainable one in the rigorous sense of the word, but for large-scale buildings, its use cannot be avoided. At the same time, rein-forced concrete, in its many forms, is a versatile building material that can provide many sustainable
