MATERIAL

Name
Fly Ash Bricks

Description

The Wesrn Court Annexe project uses a combination of fly ash bricks and C&D block masonry to ease construction in a time frame. These materials are readily and readily available compared to other options. This helped in faster construction at the time of execution.

Fly Ash Bricks  (FAB) is a building material, especially masonry units, which contain class C or class F fly ash and water. Compressed at 28 MPa (272 atm) and fixed for 24 hours in a 66°C steam bath, then hardened with an air entrainment agent, the bricks last for more than 100 freeze-thaw cycles. After 15 – 20 days of production, fly ash bricks are sold in the market.

Advantage:

a.20-40% due to the right size savings in cement mortar for making and plastering walls
b. The strength of the supply lot is the same.
c. Plaster of Paris, putty can be applied directly without a backing coat plaster.
d. Less water penetration in clay bricks.
e. Can be used for high strength-bearing walls.
f. Eco-friendly using fly ash.

Implementation Strategy

1

Architectural planning:

  • Identification of land- The Western court building with rear unutilized land had been earmarked for the additional requirement of Suites for MP’s.
  • Concept evolution-The our storied with linear & symmetrical plan, designed in harmony with the Western court, a grade II heritage building in terms of its height and façade.
  • Components- It has 88 guest suites with double occupancy having a balcony and kitchette, dining area with kitchen, Gymnasiums, Meeting rooms, yoga room and multipurpose hall. The accessible suite is also provided at ground floor level .The parking facility is provided at surface as well as in the basements. The traffic movement is provided by means of 6 mtr wide internal roads and integrated with the existing vehicular movement pattern of the whole campus.
  • Landscape- the landscape of the site holds aesthetic value adding glory to the building while keeping the campus dominantly green. The design in both front lawns are symmetrical and justifying the symmetrical form of the building. The limited scope of landscape with its intricate detail all around the building plays major role in adding value and meaning to overall project.

Structural planning:

  • It is R.C.C. frame structure and earth quake resistant building.     The building designed on the basis of latest IS 456, IS 1893 & IS 13920.

          Other services:

  •  The project has housed electrical substation, Pump room, VRV system etc. It is  one such building where  through use of LED lighting and solar power generation, CO2 emissions have been reduced to 226.4 ton/year. The total saving of energy consumption due to provision of led light fitting including pole lights instead of conventional light fitting and installation of 75KWP rooftop solar power plant is 251563.3 KWH.

 

           Site implementation:

  • The project has been periodically monitored from day first of its execution to last day in terms of its timely delivery without compromising the quality. The selection of material is in accordance with the suitability and availability.
