Concrete - developments

Stronger concrete will have all the desirable properties.

1995 survey report -National Cooperative Highway Research Programme(NCHRP), USA – premature deterioration of concrete bridges built with OPC –lack of durability.

Even in India premature deterioration of concrete structures within 10-20 years.

Concrete - developments

Durability was greater challenge than the strength of concrete.

Special attention to durability aspects of concrete inIS:456-2000.

Incorporation of mineral admixtures such as GGBS, Flyash, Silica fumes ... incodes mainly to enhance the durability of concrete.

IS:456 also permitted the use of PPC and PSC.

Concrete - developments

Infrastructure development is undergoing transformation. It has beenrecognised that the use of OPC alone or using OPC in high percentage inconcrete is not only coming in the way of Greener construction (Sustainability)but also leads to many disadvantages in particular with the following:

a. Drying shrinkage

b. Excess heat of hydration

c. Continued increase in permeability

d. Lack of resistance to chemical attacks

Strength Durability Sustainability

Concrete - developments

Sustainability

It is the ability to sustain or capacity to Endure.

To make our natural resources available to our future generation.

Use of natural resources responsibly without harming

Environment.

It is doing more with less(Natural resources)

“I need” based living not “I want” based living.

Slag v/s Flyash

SLAG FLYASH

Source Blast furnace – quenching of molten material

Thermal Power Plants – fine residue of combustion

Chemical composition Similar to that of Cement high SiO2 and Al2O3, but low in CaO

Hydration Hydraulic Non -hydraulic

Permitted replacement to cement 25 – 70 % 15 -35%

Production process Very stringent – stable chemical composition of slag

Not as stringent as in case of Steel / Iron

PSC

PSC

JSW Slag Products (PSC/GGBS)- Eco Friendly

The products of BF Slag are highly regarded as environment friendly materials that canprotect the environment by limiting the exploitation of natural resources and reduce theamount of energy consumed in the mining of natural Resources.

Sustainable & Environmental Friendly

Pollution (Air, water & land) free environment ensures no adverse impacts on the health of nearby communities,

Utilization of slag and other by-products minimize burden on landfills,

Reduced virgin material usage,

Reduced fossil fuel usage,

Huge GHG emission reductions and hence direct contribution to reversing the effects of global warming and climate change.

Low Carbon Concrete (LCC)

The contribution of construction industry to the total Green House Gas (GHG) emissions is

estimated at approximately 8%. With the annual production of concrete worldwide is

approaching 200 billion tonnes.

Research study shows that, use of Ground Granulated Blast Furnace Slag, low

carbon concrete can be produced, reducing carbon dioxide emission by about 60%

and at the same time quality of concrete is improved.

GGBS manufacture typically releases 52 Kgs of CO2 / MT which is about 5% to that of

OPC production.

CONCLUSIONS

JSW products have enormous potential to extend a structure’s useful service life becauseit improves concrete durability in areas susceptible to corrosion resistance, sulphateattack and alkali silica reaction.

Improved durability characteristics help further reduce life-cycle costs, lowermaintenance costs and makes concrete more sustainable.

The concrete produced from PSC & GGBS is lighter coloured with higherreflectivity.

Lighter coloured pavements produce higher visibility and improved safety.Buildings and pavements that are lighter in colour reflect more light and thus helpminimize the ‘heat island’ effect which in turn reduces the energy needed forcooling.

PSC is used to make durable concrete structures rather than Ordinary

Portland Cement. It has been reported that PSC has represented high

percentages of total production in many countries in recent years.

West Germany – 24%, Belgium – 32%, France – 42%, Netherlands – 55%

PSC has been widely used in Europe, and increasingly in the United States

and in Asia (particularly in China, Japan and Singapore) for its superiority in

concrete durability, extending the lifespan of buildings from fifty years to

hundred years
