Definitions

  • Limestone is the most important source of cal ⁇ cium carbonate. It is abundant in or near every land area of the world.
  • granulated blast furnace slag is thoroughly mixed or "blended" with kiln dust, the waste product of the Portland cement production process or with calcium carbonate, or both.
  • the result. is a cemen- titious, hydraulic setting product that can be substituted for all or part of the Portland cement in mortar and con ⁇ crete.
  • the undesirable effects that characterize the re- tention of highly alkaline kiln dust in Portland cement are avoided in large measure by inclusion of the slag. As much as half dust and/or calcium carbonate, and even more, can be included in the blend even when no Portland cement is included.
  • concrete made according to the invention is excellent for use in both concrete and mortar, particularly when the slag-dust- calcium carbonate blend includes one-half or more of slag.
  • the most useful range of proportions extends from ninety parts slag and ten parts kiln dust and/or calcium car ⁇ bonate to seventy parts slag and thirty parts dust and/or calcium carbonate.
  • the proportion of that blend to Port ⁇ land cement is variable over the full range from all slag- dust-calcium carbonate to all Portland cement except that hardening is slowed materially in concretes and mortars made with twenty percent or less of Portland cement.
  • Tests indicate that for use in concrete the best blend comprises about four parts by weight of slag to one part of calcium carbonate or of kiln dust, or both. That ratio makes a good strong cement when mixed with Portland cement in any ratio of the blend to Portland cement from one to four to all blend. Strength is less when the mixture includes only twenty percent or less of Portland cement. However, it is possible, and even likely, that the reduction in strength when the percentage of Portland cement is low is simply the manifestation of slower hardening that occurs when higher proportions of Portland cement are included.
  • the symbol "X" means 16 fluid ounces of liquid per one hundred pounds of -slag-dust blend.
  • a numeral in that column means the number ofucid ounces of liquid accelerator per one hundred pounds of slag-dust blend.
  • Blend S0 3 % Compressive Strength Mix % % of Percent of Control
  • High-range water reducer was included in the cement/blend mixes at 0.5% by weight of the weight blend.

Abstract

Ciments améliorés servant à la fabrication de béton et de mortier comprenant un mélange de carbonate de calcium moulu ou d'une poudre de ciment Portland séchée au four, ou des deux, avec du laitier de haut-fourneau granulé moulu. Tandis que ces caractéristiques physiques et chimiques sont différentes de celles du ciment Portland, ce ciment est un substitut fonctionnel du ciment Portland et peut être utilisé en combinaison avec le ciment Portland dans une large gamme de proportions. La prise et d'autres caractéristiques de ce ciment de laitier-poudre peuvent être améliorées par l'addition de SO3, en général en ajoutant du gypse moulu et par l'utilisation d'accélérateurs et de composés de formaldéhyde de réduction d'eau.
