GCP Applied Technologies offers CONCERA™, a new concrete admixture that can speed up construction and deliver a higher quality finish for better overall efficiency.
GCP Applied Technologies is now offering its CONCERA™ admixture for construction projects across India. The advanced concrete admixture creates Control Flow Concrete. Its advantages include: A reduced need for skilled labor and equipment on site; faster construction and improved build quality.
CONCERA™ produces Control Flow Concrete that is highly flowable and segregation resistant. It is also easy to apply and requires only minimal vibration. So, workers can pump the concrete where it is needed with minimal additional supervision. CONCERA™ has a high tolerance to variations in its raw materials, delivering higher consistency and allowing for more manageable quality control.
'Using CONCERA™ to create Control Flow Concrete allows contractors to use conventional concrete to get unconventional results,' said Dr Jiang Jia Biao, Specialty Product Manager, GCP Applied Technologies.
'It is a robust product that eliminates the concerns contractors have with conventional concrete. Labour costs are an increasingly important issue in India, but with CONCERA™, contractors can limit the skilled workers needed on site, because the technical process of vibrating concrete is minimised.'
Breaking an age-old habit
Many contractors remain unaware of advances in concrete technology. Between 97-99 per cent of projects worldwide still use conventional concrete with few chemical admixtures. Because self compacting concrete (SCC) has a highly flowable nature and requires little or no vibration, it appeals to contractors. In most cases, the extra cost for SCC may limit its use, but with CONCERA™ there's now a viable alternative.
One of the biggest advantages of CONCERA™ and Control Flow Concrete is that it offers comparable fluidity to SCC, yet its costs are closer to conventional concrete. In a study conducted by GCP Applied Technologies, a 4,600 sq m deck was constructed in an hour less and with three fewer workers when using Control Flow Concrete with CONCERA™ vs conventional concrete.
Strength and quality
CONCERA™ is added to the concrete mix at the batching plant. So, it is ready to pump the moment it arrives on site. Its rheology control means it not only offers better flowability but there is no segregation or bleeding. This is particularly relevant for high-rise construction, where high strength concrete is needed for long-term durability and strength.
But, to get higher strength from conventional concrete, it needs a thicker mix, and this can be challenging to pump. But with CONCERA™ and Control Flow Concrete, there are no such concerns.
Customising, optimising results
GCP Applied Technologies works with concrete producers and contractors to tailor the right CONCERA™ admixture for every project. It has a network of specialists across India who understand local construction methods, materials and building environments to ensure the right product for projects.
CONCERA™ admixtures are now available across India; the projects using the new technology have already been completed favourably. It has been featured in a range of primary applications including: Horizontal slabs, elevated decks, vertical walls and columns, tunnel linings, bored piles and projects requiring speedy construction.
