Definitions
- the granulated slag For the production of supersulphated cement, the granulated slag according to the German standard must contain at least 13% by weight Al 2 O 3 and correspond to the formula (CaO + MgO + Al 2 O 3 ) / SiO 2 > 1.6. According to Keil, an amount of 15 to 20% clay slag with a minimum modulus of (CaO + CaS + 0.5 MgO + Al 2 O 3 ) / (SiO 2 + MnO)> 1.8 is preferred. According to Blondiau, the CaO / SiO 2 ratio must be between 1.45 and 1.54 and the Al 2 O 3 / SiO 2 ratio between 1.8 and 1.9.
- a hydraulic binder containing CaSO 4 , blast furnace slag and thermally treated clays and marls is further developed such that burnt oil shale is used as thermally treated clays and marls and that organic and / or inorganic alkali and / or alkaline earth compounds are used as strength improvers .
- burnt oil shale is used as thermally treated clays and marls and that organic and / or inorganic alkali and / or alkaline earth compounds are used as strength improvers
- supersulfated cement can be formed without another activator such as clinker, cement kiln dust or alkalis.
- the use of burnt oil shale in the composition of the present invention improves late strength and reduces shrinkage while additionally achieving reduced oxygen permeability, which in turn results in improved durability of the binder product.
- strength improvers in the form of organic and / or inorganic alkali metal and / or alkaline earth metal compounds are used according to the invention.
- Table 1 compares a composition of a prior art binder with a composition of a binder according to the invention. Table 1:
