Abstract
A cementitious multi-component mortar system contains finely ground Portland cement clinker with a grinding fineness in the range of from 6,000 to 12,000 cm2/g. The cementitious multi-component mortar system can be used as an inorganic chemical fastening system for anchoring elements in mineral substrates.
Claims12
A cementitious multi-component mortar system for inorganic chemical fastening of anchoring elements in mineral substrates, comprising:
- finely ground Portland cement clinker with a grinding fineness in a range of from 6,000 to 12,000 cm2/g,
- a sulfate carrier selected from the group consisting of calcium sulfate, sodium sulfate, lithium sulfate, magnesium sulfate, and potassium sulfate, wherein the sulfate carrier is a mixture of anhydrite and hemihydrate,
- silica fume,
- wherein the cementitious multi-component mortar system is a two-component capsule mortar system, and
- a mortar prepared from said cementitious multi-component mortar system has an internal strength of 4.5-20.7 N/mm2.
A method of increasing load values of an inorganic chemical fastening system for anchoring elements in mineral substrates, the method comprising:
- mixing finely ground Portland cement clinker with a grinding fineness in a range of from 6,000 to 12,000 cm2/g into a cementitious multi-component mortar system;
- wherein the cementitious multi-component mortar system further comprises:
- a sulfate carrier selected from the group consisting of calcium sulfate, sodium sulfate, lithium sulfate, magnesium sulfate, and potassium sulfate, the sulfate carrier is a mixture of anhydrite and hemihydrate;
- and silica fume;
- and
- a mortar prepared from said cementitious multi-component mortar system has an internal strength of 4.5-20.7 N/mm2.
