Translation of "Unslaked" in German

Women colored their hair to a light red hue with unslaked lime.

The reaction of the unslaked lime results in the formation of heat, thus accelerating the heating of the waste material significantly.

The chemical balance lies in this case on the side of unslaked lime due to the heat introduced.

If however, the slaking heat of unslaked lime, which is used as a starting material, is added, then a cooling, such as by a corresponding reduction of heat, etc., must be accomplished.

Whenever slaked lime is used instead of unslaked lime, the former is fed to mixer 3 from silo 1" just like the sand, as shown in a broken outline in FIG.

Alternatively, it is also possible to work with unslaked lime and Portland cement, as in the case of foam concrete, and hence, if appropriate, without thermally activatable quick-setting cement, in which case the crude mixture is introduced into a mold and a rigidifying hydration reaction of the Portland cement is initiated by the slaking heat of the lime, resulting in the setting of the crude mixture.

Numerous additives can be added to the base material which is especially lime hydrate or fine white lime or to the water used for slaking the unslaked lime. Such additives include especially powdered clay, burnt clay, bentonites, thixotropic bentonites with a high montmorillonite content, gas concrete dust, expanded clay, ground fines from production of limestone bricks or production of yalistone (translated from the German "yalisteinherstellung"), powdered trass, trass lime, bleaching earths, cements, calcium aluminates, sodium aluminates, calcium sulfide, organic sulfides, calcium sulfite, carbonaceous sorbents such as blast furnace coke, lignite dust, activated carbon and ground or untreated flue ash from burning hard coal as well as water glass and accelerators and/or retarders of hydraulic setup such as those conventionally used in the cement industry (for example, such pore-forming substances as Addiment LP1 and LP2, foaming agents 1 TM and 4 TM or retarder VZ).

Drying in step II can be performed within the scope of this invention by supplying energy of any type or preferably by reaction with a suitable amount of unslaked lime.

In process variants Ia and Ib the pore-forming agent, if it is not gaseous, for example, if it is aluminum powder or zinc powder, may be placed in the starting mixture together with the unslaked lime, or as an alternative, it may also be added to the slaking water.

To the flowable slurry are added first 5.0 kg of Portland cement, then 24.5 kg of unslaked lime, and then 12.0 kg of "scraping mud" (residue containing the indicated components which is left over after the molding process). A sufficient amount of water is added to ensure that the total weight of the water is 58.5 kg and finally, 0.14 kg of fine aluminum powder.

To this slurry is first added 5.0 kg of Portland cement, then 24.5 kg of unslaked lime having a CaO-content of 86 percent by weight, and thereafter 12.0 kg of so-called "scraping mud" (residue containing the indicated components remaining after the molding process).

In the methods for producing cement which are carried out most often throughout the world, a calcium carbonate-containing initial material in the form of limestone is freed of CO 2 formally by the supply of heat and is thereby converted into unslaked lime, calcium oxide, and is subsequently sintered by the supply of even more heat, in the presence of silicate-containing rock, into cement clinker which is composed of various calcium silicate phases and constitutes the principal fraction of customary cement.

Suitable mineral binders are, for example, cement, in particular portland cement, aluminate cement, in particular calcium sulfoaluminate cement, trass cement, slag cement, magnesia cement, phosphate cement or blast furnace cement, and also mixed cements, filling cements, fly ash, microsilica, slag sand, hydrated lime, white hydrated lime, calcium oxide (unslaked lime) and gypsum plaster.

The Ca hydroxide and/or Ca oxide and/or Ca mixed oxide may be, for example, unslaked lime or slaked lime, CaO, Ca(OH) 2 .
