Abstract
The invention is related to nanocement production methods by modifying Portland cement, as well as to nanocement compositions. The nanocement production method involves a mechanochemical activation of dispersed grains of Portland cement in the presence of polymeric modifier, with the sodium naphthalenesulfonate content of at least 60 wt %, mineral siliceous additive containing at least 30 wt % SiO2 and gypsum, to form continuous nanoshells—capsules of 20-100 nm in thickness on Portland cement grains made of sodium naphthalenesulfonate structured by calcium cations.
Claims18
A method of producing nanocement involving a mechanochemical activation of dispersed grains of Portland cement in the presence of polymeric modifier comprising the steps of:
- identifying a quantity of Portland cement or Portland cement clinker;
- identifying a quantity of gypsum stone;
- identifying a polymeric modifier comprising sodium naphthalenesulfonate at a composition by weight of at least 60% of the polymeric modifier;
- identifying a siliceous additive;
- selecting the quantity of Portland cement or Portland cement clinker to have a weight percent of the total composition between 30% and 90%;
- selecting the quantity of gypsum stone to have a weight percent of the total composition between 0.3-6.0%;
- selecting the quantity of polymeric modifier to have a weight percent of the total composition between 0.6-2.0%;
- selecting the siliceous additive to have a balance of the weight percent of the total composition;
- combining the selected quantity of Portland cement or Portland cement clinker, gypsum stone, polymeric modifier, and siliceous additive in a grinding apparatus, the grinding apparatus configured to reduce an average particle size of the combined materials;
- grinding the combined materials by the grinding apparatus;
- wherein the step of grinding forms a nanoshell of sodium naphthalenesulfonate encapsulating a plurality of grains of the quantity of Portland cement or Portland cement clinker;
- and
- removing the combined materials after the grinding step after a desired average particle size is achieved by the grinding step.
A nanocement comprising:
- a quantity of Portland cement or Portland cement clinker, a plurality of Portland cement or Portland cement clinker having a sodium naphthalenesulfonate nanoshell encapsulating each of the plurality of particles, a weight percent of the total composition of the Portland cement or Portland cement clinker between 30% and 90%;
- a polymeric modifier comprising sodium naphthalenesulfonate having a weight percent of the total composition between 0.6-2.0%;
- a gypsum stone having a weight percent of the total composition between 0.3-6.0%;
- a siliceous additive to have a balance of the weight percent of the total composition.
