Embodiment

[0077] materials used

[0078] Additive composition A consists of 75% metal chlorides (24% NaCl, 1% NH 4 Cl, 3%AlCl 3 .6H 2 O, 16% KCl, 15% CaCl 2 .2H 2 O, 16% MgCl 2 .6H 2 O) and 25% silica.

[0079] Additive composition B consists of 82% metal chloride (31% NaCl, 1% NH 4 Cl, 3%AlCl 3 .6H 2 O, 16% KCl, 15% CaCl 2 .2H 2 O16%MgCl 2 .6H 2 O), 3% metal oxide (MgO), 3% metal carbonate (Na 2 CO 3 ) and 10% zeolite.

[0080] Basic component Q is ferruginous masonry sand.

[0081] Base component R is a 30 / 70w / w mixture of plastic clay and ferrous masonry sand.

[0082] Base composition S is a 40 / 60w / w mixture of ferrous masonry sand and E-fly ash. E-fly ash from Vereeniging collected from the bottom area of ​​the settling tower of the Lethabo Power Station was chosen as the E-fly ash for this example. However, E-fly ash from Matla, Kendall or Kelvin had similar results. The chemical composition determined by XRF of the fly ash is shown below.

Abstract

The present invention relates to a binder composition comprising a) an ash, b) an additive composition, wherein the additive composition comprises one or more components from group (b1) and one or more components from group (b2), wherein group (b1) consists of metal chlorides and wherein group (b2) consists of silica, zeolite and apatite, and c) a cement. In addition to that the present application relates to a construction composition comprising the present binder composition and a basic component, and also to a method for preparing the construction composition and to uses thereof.

Description

technical field [0001] The present application relates to a binder composition comprising ash, an additive composition and cement. In addition, the present application relates to a construction composition comprising essential components and said adhesive composition, and also to a method for obtaining this construction composition and its use. Background technique [0002] From WO 2005 / 087687 by the present inventors, a composition is known comprising 90.0-99.9% by weight of ash, 0.1-10.0% by weight of additives comprising metal chlorides and silica, zeolite or apatite and 0.0 - 5.0% by weight cement construction composition. Such compositions are used to recover large quantities of ash, for example in construction compositions for reinforcing substructure materials. However, such compositions are not suitable for certain structural and basic building applications. [0003] From WO 2004 / 087600, a cementitious composition is known comprising: a pozzolonic material; a comp...
