Blurb/Shorttext:
Green concrete employing industrial by-products covers the obstacles and knowledge gaps in manufacturing green and sustainable concrete, as well as infusing with ground granulated blast furnace slag and paper sludge as a self-curing agent. The book is well-designed to help you learn about green concrete. The book's distinguishing feature is that, in addition to a focus on core principles, all the topics are expanded according to Indian norms. Test methodologies for material properties, mechanical properties, durability qualities, and microstructural analyses are included in the book. The book has extensive results as well as a snappy conclusion. As a result, the book includes in-depth information on the green concrete concept, which originated around the turn of the century, and attempts to replace the components of regular concrete wholly or partially with waste or recycled resources. Indeed, the term "green concrete" has been broadened to cover not only waste materials but even nano-engineered materials.

  2. Parapet
  3. Lintels
  4. Beams

In English


Basic Components of a Building

1. Roof

The roof forms the topmost component of a building structure. It covers the top face of the building. Roofs can be either flat or sloped based on the location and weather conditions of the area.

2. Parapet

Parapets are short walls extended above the roof slab. Parapets are installed for flat roofs. It acts as a safety wall for people using the roof.

3. Lintels

Lintels are constructed above the wall openings like doors, windows, etc. These structures support the weight of the wall coming over the opening. Normally, lintels are constructed by reinforced cement concrete. In residential buildings, lintels can be either constructed from concrete or from bricks.

4. Beams and slabs

Beams and slabs form the horizontal members in a building. For a single storey building, the top slab forms the roof. In case of a multi-storey building, the beam transfers the load coming from the floor above the slab which is in turn transferred to the columns. Beams and slabs are constructed by reinforced cement concrete (R.C.C).
5. Columns
Columns are vertical members constructed above the ground level. Columns can be of two types: Architectural columns and structural columns. Architectural columns are constructed to improve the building’s aesthetics while a structural column takes the load coming from the slab above and transfers safely to the foundation.

6. Damp Proof Course(DPC)

DPC is a layer of waterproofing material applied on the basement level to prevent the rise of surface water into the walls. The walls are constructed over the DPC.

7. Walls

Walls are vertical elements which support the roof. It can be made from stones, bricks, concrete blocks, etc. Walls provide an enclosure and protect against wind, sunshine, rain etc. Openings are provided in the walls for ventilation and access to the building.

8. Floors

The floor is the surface laid on the plinth level. Flooring can be done by a variety of materials like tiles, granites, marbles, concrete, etc. Before flooring, the ground has to be properly compacted and leveled.

9. Stairs

A stair is a sequence of steps that connects different floors in a building structure. The space occupied by a stair is called as the stairway. There are different types of stairs like a wooden stair, R.C.C stair etc.

10. Plinth Beam

Plinth beam is a beam structure constructed either at or above the ground level to take up the load of the wall coming over it.

11. Plinth

The plinth is constructed above the ground level. It is a cement-mortar layer lying between the substructure and the superstructure.

12. Foundation

The Foundation is a structural unit that uniformly distributes the load from the superstructure to the underlying soil. This is the first structural unit to be constructed for any building construction. A good foundation prevents settlement of the building.

 Gravity Retaining Walls

Ø  Gravity walls depend on their mass (stone, concrete or other heavy material) to resist pressure from behind and may have a 'batter' setback to improve stability by leaning back toward the retained soil.

Ø   For short landscaping walls, they are often made from mortar less stone or segmental concrete units (masonry units).

Cantilevered retaining walls

Ø  Cantilevered retaining walls are made from an internal stem of steel-reinforced, cast-in-place concrete or mortared masonry (often in the shape of an inverted T).

Ø  These walls cantilever loads (like a beam) to a large, structural footing, converting horizontal pressures from behind the wall to vertical pressures on the ground below.


Counter fort/Buttress on Cantilevered Wall

Ø  Sometimes cantilevered walls are buttressed on the front, or include a counter fort on the back, to improve their strength resisting high loads. Buttresses are short wing walls at right angles to the main trend of the wall.

Ø  These walls require rigid concrete footings below seasonal frost depth. This type of wall uses much less material than a traditional gravity wall.


Sheet pile wall

Ø  Sheet pile retaining walls are usually used in soft soils and tight spaces. Sheet pile walls are made out of steel, vinyl or wood planks which are driven into the ground. For a quick estimate the material is usually driven 1/3 above ground, 2/3 below ground, but this may be altered depending on the environment.

Ø  Taller sheet pile walls will need a tie-back anchor, or "dead-man" placed in the soil a distance behind the face of the wall, that is tied to the wall, usually by a cable or a rod.

Ø  Anchors are placed behind the potential failure plane in the soil.

Anchored retaining wall


Ø  An anchored retaining wall can be constructed in any of the aforementioned styles but also includes additional strength using cables or other stays anchored in the rock or soil behind it.

Ø  Usually driven into the material with boring, anchors are then expanded at the end of the cable, either by mechanical means or often by injecting pressurized concrete, which expands to form a bulb in the soil.
Technically complex, this method is very useful where high loads are expected, or where the wall itself has to be slender and would otherwise be too weak.
