Belite has a lower hydraulic activity than alite, which is the main component of Portland cement clinker. Belite can be prepared at lower expenditure and its hydraulic activation can have important impact on the economy and sustainability of the cement industry. This research focused on the activation of C<jats:sub>2<\/jats:sub>S by incorporation of SO<jats:sub>3<\/jats:sub> into its crystal structure. This paper describes experiments with pure chemicals that characterise substitution of SiO<jats:sub>2<\/jats:sub> by SO<jats:sub>3<\/jats:sub> and its influence on the hydraulic activation of C<jats:sub>2<\/jats:sub>S. It was confirmed that sulfur stabilises the monoclinic modification \u03b2-C<jats:sub>2<\/jats:sub>S. The maximum content of SO<jats:sub>3<\/jats:sub> in C<jats:sub>2<\/jats:sub>S under common laboratory burning conditions was approximately 4\u00b74 wt%. The hydraulic activity of prepared \u03b2-C<jats:sub>2<\/jats:sub>S doped with SO<jats:sub>3<\/jats:sub> was up to three times higher than in the reference non-activated \u03b2-C<jats:sub>2<\/jats:sub>S. <\/jats:p>","DOI":"10.1680\/adcr.11.00021","type":"journal-article","created":{"date-parts":[[2012,8,16]],"date-time":"2012-08-16T22:24:51Z","timestamp":1345155891000},"page":"233-238","source":"Crossref","is-referenced-by-count":24,"title":["Dicalcium silicate doped with sulfur"],"prefix":"10.1680","volume":"24","author":[{"given":"Theodor","family":"Stan\u011bk","sequence":"first","affiliation":[{"name":"Head of Section, Binding Systems, Research Institute of Building Materials, Brno, Czech Republic"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Petr","family":"Sulovsk\u00fd","sequence":"additional","affiliation":[{"name":"Research Worker, Research Institute of Building Materials, Brno, Czech Republic"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"140","reference":[{"key":"adcr-v24i4p233r1","first-page":"135","volume":"370","author":"Anda\u00e7 M","year":"1995","journal-title":"Materials Research Society Symposium Proceedings"},{"key":"adcr-v24i4p233r2","volume-title":"BS 12:1958.
