Cenin are currently manufacturing and delivering two specific ultra low carbon cement replacement products from thoroughly tested, carefully graded, industrial by-products
Cenin (SDP) is predominantly a Pozzolanic material that is similar in chemical composition to a calcareous fly ash as described in European Standard EN197-1:2000, Cement, Part1: Composition, specifications and conformity criteria for common cements.
Cenin (SDP) like calcareous fly ash is a fine powder, having hydraulic and/or Pozzolanic properties. It consists essentially of reactive calcium oxide (CaO), reactive silicon dioxide (SiO2) and aluminium oxide (Al2O3). The remainder contains iron oxide (Fe2O3) and other compounds.
Cenin Semi-Dry Product is a specialist blend formulated for high early strength in semi dry product manufacturing. Key features include:
From extensive testing and analysis this blend has proven suitable for use in the manufacturing of concrete blocks, block paving and for soil stabilisation.

Cenin (WCP) is predominantly a latent hydraulic material that is similar in chemical composition to a calcareous fly ash as described in European Standard EN197-1:2000, Cement, Part1: Composition, specifications and conformity criteria for common cements.
Cenin (WCP) like calcareous fly ash is a fine powder, having hydraulic and/or Pozzolanic properties. It consists essentially of reactive calcium oxide (CaO), reactive silicon dioxide (SiO2) and aluminium oxide (Al2O3). The remainder contains iron oxide (Fe2O3) and other compounds.
Cenin Wetcast Cement is a blend which is suitable for all general concrete applications.
From extensive testing and analysis this blend has proven ideal for use in readymix concrete and wetcast situations.

These products have been developed and driven by industrial demand and are truly based on technical performance.
Over fifty industrial by-products have been examined, tested and recorded in an extensive database with significant results, including a wide range of slags from all sectors of the steel producing industry.
Each batch of product we supply is thoroughly tested and analysed and this data is made available to the client. We also store a sample from every load we deliver for future analysis, quality control and monitoring purposes.





The technology used to develop the cement products is based on a patented process that incorporates industrial knowledge, emission and technical control, using thermal treatment, chemical blending, and particle size analysis .
The process is an environmental and economic solution to industrial requirements based on technical performance and fully integrated quality control systems to ensure technical reproducibility.
We provide sustainable technologies that balance environmental and economic benefits for the production of technically superior cement replacements. Cenin’s technology can tailor make a product for a particular purpose and can vary characteristics such as setting time to suit seasonal variations in temperature.
This is an award winning green technology truly reducing environmental damage by not using virgin materials, low energy inputs and local transportation, our technology leads to a truly sustainable cement process. The technology has also been verified by accredited independent laboratories in the UK, the main research work was carried out at the School of Civil Engineering Cardiff University.
Typically the process modifies pozzolanic materials such as power-station fly ash, burnt clays and ash from CHP plants, material which, although they may not have cementitious properties in themselves, with the use of Cenin’s technology can be chemically engineered to create a chemical reaction with Portland cement during the hydration process to improve the properties of concrete.
Using Cenin’s technology greenhouse gas emissions are dramatically reduced because the cement is manufactured from industrial by-products negating the need for quarrying raw materials. This environmental, low-carbon benefit can be passed on to the end user.
Cenin’s adaptable system has proven higher strength, lower permeability and is more durable than concrete made with ordinary Portland cement.

Unlike any other process currently available this process can change the properties of the cementitous material to suit the needs of the end users e.g. reduce the heat of hydration in hot climatic conditions or increase the heat of hydration in harsh winter environments
Cenin is also pioneering the use of ultra low carbon energy sources such as biogas and renewable wind energy to further reduce CO2 emissions from its cement manufacturing process to practically zero.
Sites are available adjacent to our manufacturing plant at Parc Stormy, Stormydown for recycling businesses wishing to utilise the low carbon energy sources being generated nearby
