Definitions

  • the invention relates to a slag cement with improved early strength, containing blast furnace slag, aluminum silicates, clinker and CaSO 4.
  • Slag cements have long been known in various compositions. Slag cements usually contain a maximum of 50% by weight blast furnace slag. Such slag cements or metallurgical cements usually contain about 15% by weight CaSO 4 in order to achieve reasonable early strengths. The calcium sulfate or anhydrite content is decisive for the extent of early strength, whereas the hydration of blast furnace slag ensures a corresponding strength after complete hardening. In addition to slag sand and gypsum, slag cements or metallurgical cements of this type generally also contain about 5% by weight of clinker.
  • the invention now aims to provide a metallurgical cement of the type mentioned at the outset, with which high early strengths can be achieved with a low CaSO 4 or anhydrite content.
  • the slag cement or metallurgical cement according to the invention is essentially characterized by a content of 70 to 95% by weight in ground form with> 4500 Blaine (cm ⁇ / g) blast furnace slag used, the proportion of which is at most half by aluminosilicates such as fly ash, alumina, marl or the like can be substituted, 0.1 to 2% by weight of clinker, sulfate in amounts of less than 5% by weight, calculated as SO3, and 0.3 to 1% by weight of a superplasticizer.
  • blast furnace slag can be used in amounts of up to 95% by weight without loss of early strength if the boundary conditions for the clinker content and the sulfate content as well as the proportion of super-liquefier are maintained at the same time.
  • blast furnace slag in ground form with> 4500 Blaine (cm ⁇ / g) is used.
  • the amount of gypsum or calcium sulfate or anhydride must be limited accordingly, as already mentioned at the beginning.
  • the metallurgical cement or slag cement according to the invention advantageously contains clinker in an amount of about 1% by weight.
  • blast furnace slag with> 5000 cm 2 / g Blaine, preferably gypsum in amounts of ⁇ 5% by weight.
  • the invention is explained in more detail below on the basis of the strength development of various compositions.
  • Fig. 1 shows the strength profile of a mixture of blast furnace slag and 10% CaSO 4 depending on the clinker content
  • Fig. 2 shows the strength profile of blast furnace slag, 10% gypsum and 0.7% naphthalene sulfonate depending on the clinker content
  • Fig. 3 shows the strength profile of a slag cement according to the invention with blast furnace slag, 5% CaSO 4 and 0.7% naphthalene sulfonate depending on the clinker content in% by weight.
