Acceptance Criteria
At present there are no official criteria to determine what by-products are acceptable for use in concrete. Therefore, as a company we are working with the Building Research Establishment (BRE) UK to obtain accreditation for the process and products for acceptance to the industry.
We have developed an analytical system to fully characterise the raw materials to establish the suitability of the individual or blend of materials for use as a cement substitute. This characterisation ensures us that the end product will pass all the relevant tests in accordance with the European standards for Portland cement.As a final check we use X-ray diffraction (XRD) to establish what compounds are forming with time.
It is well known what compounds form in Portland cement with time, we also know the compounds that form with composite cements using GGBS and PFA. Therefore, we evaluate our raw materials or blends of materials to ensure that these compounds are not adversely affected by our materials.
Technical performance
We have produced cement substitutes that can out perform GGBS and PFA over the first seven days of strength development and at twenty eight days they fall between that of GGBS and PFA, these substitutes are flexible and can be altered to equal the performance of GGBS or PFA.

Global Slag Conference
November 2007
We presented a paper at the Global Slag Conference in Istanbul, Turkey 19 - 20 November. We demonstrated how Celtic Cement Technology can improve both the properties of slag cement and its environmental impact.
Patent Approval
August 2007
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 enviromnent. Further testing on a diverse range of industrial waste materials has taken place in the meantime with fantastic cementatious properties being achieved.
