Here's what Dalmia, ACC and Ramco Cements are innovating for blended cement

Companies that opt to buy blends must choose from different kinds of blends and decide on the extent of the blend. 'Consider the design parameters and the expected performance of the product vis-a-vis usage requirements when selecting a cement blend,' explains Manoj Rastogi, Senior Vice President, Concrete Products Division, Sobha. 'The outcome achieved is measured for its durability and the performance of the material vis-a-vis standalone fly-ash. Our objective is to achieve a good product at minimal cost.'

Nano Concrete, a new product from INSWAREB, can be made on site with a roller blender by anyone who obtains the mix details from the developer.

Essentially, cement can be blended on site. However, this necessitates 'a facility to evaluate the quality of the blending materials to control the quality of the mix,' cautions Anil Kumar Pillai, Senior Deputy General Manager, Technical Services, The Ramco Cements, pointing out that 'buying blended cement can be easier and safer'.

Dalmia Cement (Bharat) offers binary blends such as Portland Pozzolana Cement (PPC) and Portland Slag Cement (PSC) and the latest ternary blend (composite cement) with the benefits of both, lime rich slag and silica rich fly-ash. PPC, PSC and Pozzolona Composite Cement (PCC) perform exceptionally well in moderate exposure conditions and have 30-40 per cent lower carbon footprint than conventional cements. Dalmia PPC, slag and DSP have started becoming a viable replacement to OPC in mass housing projects as it matches the requirement of strength of OPC.

ACC offers five blended cements: ACC Concrete+Xtra Strong with compressive strength standards higher than the BIS-prescribed norms for PPC, ACC F2R Superfast with a super-fast setting formula that accelerates construction speed, ACC Gold Water Shield with water-repelling properties, ACC Suraksha Power with unique properties for the most dense and impermeable high strength concrete resistant to corrosion, and ACC HPC Long Life specially engineered slag cement ideal for dense, corrosion-free and crack-resistant concrete.

The Ramco Cements manufactures blended cement using the best quality pozzolanic material and slag under the brand name Ramco Supergrade (PPC) and Ramco Super Steel (PSC).
