Quenching and Self Tempering (QST) imparts a composite micro structure ranging from a strong, tough, tempered martensite in the surface layer to a refined, tough, ductile ferrite-pearlite in the core with a intermediate structure in between. Superior rib design for excellent bonding with cement. Mean Projected Area much more than the specified values of the IS1786 standard.

Advantages ..of TMT (QST) Rebars of VSP Combination of high strength and high ductility VIZAG TMT bars have rare combination of high strength with excellent ductility. The tensile to yield strength ratios are always greater than 1.12. In normal bars, the increase in the yield strength of the bars is accompanied by the loss of percent elongation. But in the case of VIZAG TMT bars this loss is negligible and the percent elongation values are much higher than normally specified in various International Standards. In Fe 500D grade rebars the UTS/YS ratio values are maintained always at more than 1.15. Resistance to ageing The tests carried out on the VIZAG TMT bars, indicate that no significant change of strength as a function of time occurs which could affect the usefulness of these bars. Superior corrosion resistance The absence of Eutectoid Carbides and pearlite colonies in VIZAG TMT , absence of stresses because of tempering, presence of martensitic layer at the outside surface and formation of adherent scale film due to water quenching during rolling are the reasons for better corrosion resistance properties of these reinforcement bars.

Excellent bendability and workability The tough outer skin and the ductile core of the VIZAG TMT bars result in excellent bendability. This coupled with a high resistance to low temperature brittle fracture, allows these bars to be bent, without fear of failure around small diameter mandrels. In the reverse bend test, these bars also show good results. In the construction site, situation arises where bars bent are left for a period in the bent condition and then reverse bent. During period between the first bend and the reverse bend the bars may strain age. The loss of ductility due to strain ageing and due to strain imposed from the first bend may cause failure during rebending operations, if the bars are not sufficiently ductile. Test results have shown that VIZAG TMT bars have withstood successfully the bending, straightening and rebending tests after ageing. The bend tests carried out at VSP have shown that these bars could be bent even around smallest dia mandrel without causing any cracking

The only plant to adapt this technology (QST) for production of rebars from the design stage. Hence, the total extent of the superior technology could be harnessed. 120 metres length of the cooling bed available for self tempering which no other mill in India can match is the testimony for this.

UltraTech Super

Build your identity, not just your home

Designed to be strong and durable over the long term, UltraTech Super Cement is ideal for modern-day construction techniques such as fast-track construction. Blended cement is a type of cement that has had a portion of the clinker replaced with other ingredients.


It uses additional raw materials in comparison to OPC, such as refined HRS and refined Gypsum. it is a type of Portland Pozzolana Cement (PPC). UltraTech Super is a new generation of cement that incorporates advanced technology, computerised process controls, and online quality control to ensure high-quality work, always. 

Blended cement is a type of cement that has had a portion of the clinker replaced with other ingredients. At the grinding stage of cement manufacture, additives, such as fly ash, granulated BFS, silica fume, volcanic ash, and other by-products, are mixed with the clinker in varying amounts. 

The use of blended cement is an appealing efficiency option because adding these additives helps to minimize the amount of energy utilised. It is also useful in reducing greenhouse gas emissions from clinker production, and carbon dioxide emissions from calcination directly. 

 

 

This is why blended cement is expanding into new markets and its application is increasing and becoming more popular across the world.

Importance Of UltraTech Super

 

• UltraTech Super is designed to provide rapid construction, quick removal of shuttering/form work, sustainable construction, higher coverage, and smoother finishing to your work.
• Since it is a blended cement, it has a lower carbon footprint than OPC 53. It is a sustainable product which helps in reduction of emissions from carbon dioxide and greenhouse gases. While being sustainable, it is also a durable cement that provides the best quality work.
