Ternary Blends of Portland Cement, Bottom Ash and Silica

What Is Blended Cement and What Are Its Advantages

Blended cement is obtained by mixing OPC with mineral admixtures or additives like fly ash, slag or silica fumes. Blended cements are now being considered superior as compared to conventional OPC category of cements. Blended Cement Advantages of Blended Cement. The advantages of using blended cement can be broadly be divided in two categories i.e.

PDF Partial Replacement of Cement with Ceramic Waste and Pond

production of Portland Pozzolans Cement, a replacement of ordinary Portland cement. 20% of residue of burnt coal, collected in the water-impounded hopper below the boilers is called bottom ash. It is generally used for fills, embankments and road construction. Pond ash is a mixture of bottom ash and fly ash as available in ash ponds.

Experimental Investigation on Ternary Blended Concrete

Fly ash from coal fired power plants and metakaolin are both important in modern concrete technology. Enlarging the scope of material science to Supplementary Cementious Materials (SCM) viz., fly ash, slag, silica fume, rice husk ash and Metakaolin in the use of concrete, this led to the concept of blended cements and blended concretes.

In the ternary calcined gypsum-lime-pozzolan blends, which were studied to date, fly ash was the most frequently used. Singh and Garg [5] investigated a blended binder consisting of 40% calcined phosphogypsum, 40% fly ash and 20% hydrated lime and observed an increase in compressive strength up to 90 days.
