“…The spectra show the three characteristic peaks of the diffraction planes (100), (110) and (200) of the 2-d hexagonal space group p6mm of the SBA-15 [3,20]. The definition and position of these peaks is related to the mesoporous hexagonal symmetry, i.e., lower values indicating a more ordered structure [17,48,49]. The relative position of the peak of the plane (100) of sample H0 is shifted to higher values of 2θ, while the peak (110) practically does not appear and the (200) peak moves to higher values, indicating a poorly organized structure.…”

The synthesis of SBA-15 has been optimized using sodium silicate, an inexpensive precursor of SBA-15. In this work, the influence of synthesis times of the precipitation and the hydrothermal treatment steps, on the textural properties developed as well as for reducing the toxic compounds generated in tobacco smoking, has been studied. The hydrothermal treatment has been proved to be necessary to obtain materials with adequate performance in this particular application. Twenty-four hours of hydrothermal treatment provide materials with the best properties. Although the reaction stage usually involves the mixing of reagents during 24 h, 40 min is enough to obtain a material with stick-like morphology and typical textural properties. Moreover, between 1 and 2 h of reaction time, the material proved to have the best performance for the purpose of reducing the toxicity of the products generated during the tobacco smoking process. These results are of great significance for an eventual scaling up to industrial scale of the SBA-15 manufacturing process. Results of a pilot plant experiment in a batch of 4 kg of SBA-15 are reported.

Concrete was successfully produced using rice husk ash (RHA) as a partial cement substitute. RHA was mechanochemically treated using ball mill as mechanical force and acids (HCl and CH3COOH) as chemical force. Mechanochemical treatment decreases particle size as demonstrated by particle size analyser test and reduces crystallinity of RHA as demonstrated by X-ray diffraction analyses. These characteristics make RHA more suitable as partial substitution of cement as well as pozzolanic material. The compressive strength of concrete increases 11-26 % by addition of RHA as cement substitution. The significant increase of compressive strength was obtained from RHA mechanochemically treated with HCl which has compressive strength of 14.8 MPa in comparison of standard concrete which has compressive strength of 11.72 MPa.
