Cement Replacement manufacturing progress

Here we are documenting the progress of our cement replacement manufacturing technology and the development of our own cement replacement. You can read about the current activities of the business and the additional progress we are making on the expansion of our manufacturing plant at Stormydown.

Visit to Cenin Cement by the Chinese Ambassador to the UK and his wife.

Cenin were very pleased to host this prestigious visit in March 2011 in conjunction with the Welsh Assembly Government. The Ambassador and his wife were given a complete tour of the Ultra Low Carbon Cement Replacement, manufacturing facility at Parc Stormy, Bridgend. The party were keen to know more about how our patented technology will help reduce carbon emissions in the construction industry.

Cenin see massive opportunities in most continents of the world including China for companies to use Cenin’s Unique Patented Technologies to enable the reuse of waste minerals to help tackle climate change and build more sustainable futures.

Presentation to the 'Future of Cement' Conference, London February 2011

Gary Hunt presented a technical paper and presentation at the conference. Entitled "Making High performance Low Carbon Cement Replacements from Calcareous Fly Ash" Gary pointed out how Cenin Cement Replacement technology, when used for making cement replacements from industrial waste material such as fly ash, produces a much more consistent and predictable result.

Other manufacturers experimenting with this material are experiencing inconsistent results due to a range of variations in the manufacturing process. Different fuels and admixes when used with a traditional Kiln process are causing these inconsistencies. The Cenin process bypasses the Kiln, eliminating these inconsistencies and through real-time chemical analysis produces a high performance, consistent and predictable product.

The Cenin product range is tested to the following European standards:

• BS EN 196-1:2005, Methods of testing cement, Part 1: Determination of strength.
• BS EN 196-2:2005, Methods of testing cement, Part 2: Chemical analysis of cement.
• BS EN 196-3:2005, Methods of testing cement, Part 3: Determination of setting times and soundness.
• BS EN 196-5:2005, Methods of testing cement, Part 5: Pozzolanicity test for pozzolanic cement.
• BS EN 196-6:2005, Methods of testing cement, Part 6: Determination of fineness

Over 1 million tonnes of concrete have now been made using Cenin Low Carbon Cement Replacements.

Our manufacturing plant has been successfully and consistently producing cement replacement products for over a year. We carefully monitor all product produced and samples of EVERY batch of cement replacements delivered to clients have been stored, analysed and tested for quality control and consistency. We and our clients are very pleased with the results so far.

Our external hoppers and tanker loading bay has been completed allowing us to safely and quickly load up the tankers. This speeds up delivery to the end customer. We have developed an efficient traffic system to allow the tankers easy access to the loading bay from where they can drive straight onto the weighbridge. At the weighbridge drivers collect all the necessary documentation which helps us track and trace the product from manufactured batch right through to delivery.

Our on site cement chemistry testing facility helps us maintain tight control over product consistency and each batch is tested, analysed and recorded.

The external material storage silos have now been completed. These allow us to streamline our production process by maintaining a steady supply of industrial by-products which we recycle into cement replacements.

We were thrilled to be named as the winners of the 2008 Wales Business & Sustainability Awards.

" [Cenin] has demonstrated considerable achievement in improving Wales’ environmental and sustainability credentials. The judges had an incredibly difficult job in drawing up the list of finalists and many an excellent example did not make it to the shortlist" said Peter Davies, Independent Chair of Judges, Sustainable Development Commissioner for Wales, UK Sustainable Development Commission.

He commented further " Deciding on the winners was even more daunting and there was a great deal of deliberation. The winners can feel justly proud that they are exemplars in demonstrating best practice in business and sustainability."

The judging panel also said "The new technologies developed by the company are innovative and could have a revolutionary effect on building supplies and their environmental impact. The company directors have invested heavily in the business and staff commitment to the company and their products are indisputable."

Cenin wins FIRST PRIZE:
Best Presentation at the Global Slag Conference

We are pleased to announce that our technical paper and presentation was awarded 'best presentation' at the recent Global Slag Conference in Istanbul Turkey. Papers were presented to an audience of 140 delegates from 31 countries and ours was singled out from 11 other technical papers AND AWARDED FIRST PRIZE.

We presented a paper at the Global Slag Conference in Istanbul, Turkey. Download a PDF version of our presentation (4.5mb) or the technical paper (PDF). We explained how our technology significantly improves the performance and potential of slag cement and how we are significantly reducing the carbon emissions arising from cement production.

Patent Approval

After fifteen years of detailed research and thorough testing the patent for our Celtic Cement Technology process was granted 29th August 2007, patent number GB2401104. The patent was applied for on 29th April 2003 and since that date we have been working on perfecting the process and applying it to a commercial scale environment. Further testing on a diverse range of industrial waste materials is continually taking place with fantastic cementatious properties being achieved.
