Ultra High Strength Concrete

We are conversant with the utilization of concrete having compressive strength varying from 100 to 300 kg/cm2. With the introduction of prestressed concrete within the housing industry , constant research goes on to develop concrete having very high strength.

As a result thereof it's been established that by suitable selection of fabric and by adopting the special method of production it's possible to form concrete having a compressive strength exceeding 1000 kg/cm2.

Ultra high strength concrete are often produced by improved compaction (By pressure and vibration etc) and adhesion of cement matrix to aggregates or by the adoption of cementitious aggregates.

Ultra high strength concrete are often easily produced by using high-quality coarse aggregates, synthetic aluminous fine aggregates, and cement.

Use of heat to extend the lime silica bond and therefore the use of spiral wrapping of concrete to induce triaxial stress are the techniques being tried to develop ultra high strength concrete.

Polymer concrete are often super plasticized concrete also get covered within the category of ultra high strength concrete to some extent.

By using high-strength concrete, the load-bearing capacity of columns are often increased considerably.

Hence by its use, it's possible to adopt slender columns in multi-storied buildings which besides looking aesthetically good also permits greater utilization of useful floor space.

On account of its high compressive also as lastingness , this sort of concrete finds wide application in prestressed concrete.
