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 ... in codes 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 been recognised that the use of OPC alone or using OPC in high percentage in concrete 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

Concrete - developments Strength Sustainability Durability

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.

Cement? 1 MT of OPC:  1.5 MT of Lime stone  0.25 MT of Coal  70 – 90 units of electricity  Liberates 1 MT of CO 2 Is it a sustainable product?

CONCRETE IN SEA WATER Clause 8.2.8 of IS: 456-2000 Concrete in sea water or exposed directly along the sea coast shall be M20 Grade in case of plain concrete and M30 in case of Reinforced Concrete . The use of slag or pozzolona cement is advantageous under such conditions

ALKALI AGGREGATE REACTION  8.2.5.4 (b) Use of low alkali ordinary portland cement having total alkali content not more than 0.6% (as Na 2 O equivalent)  Further advantage can be obtained by use of flyash (grade 1) conforming to IS 3812 or ggbs conforming to IS 12089 as part replacement of OPC .

Eco friendly Products of JSW Cement for Promoting Sustainable Construction  Portland Slag Cement (PSC)  Ground Granulated Blast Furnace Slag (GGBS)

Blast Furnace Slag  Non metallic product.  Consisting of glass containing silicates and aluminates of lime.  Developed simultaneously with iron in blast furnace.  Obtained by rapidly chilling or quenching with water or steam and air.

Improved Corrosion Resistant Portland slag cement/GGBS lead to increase electrical resistivity of concrete and reduce diffusivity of chloride ions from outside. The resistance to corrosion of reinforced steel in concrete is enhanced due to less proportion of chloride ions available in pore solution.
