Abstract
An exemplary process for forming a cured hybrid magnesium cement composition may include first combining a mixture of magnesium-containing material, a metal silicate inorganic polymer having a repeat unit of SiP2O7, and a salt having a non-metallic oxide anion, and then mixing the mixture with water.
Claims21
A process for forming a cured hybrid magnesium cement (HMC) composition, the process comprising:
- combining together in one step a mixture of magnesium-containing material, a metal silicate inorganic polymer having a repeat unit of SiP2O7, and a salt having a non-metallic oxide anion;
- and
- then adding water and mixing the mixture with water.
A process comprising:
- first mixing together in one step a mixture of a magnesium-containing material, a metal silicate polymer, a salt having a non-metallic oxide anion, and one or more of a linear silicone polymer, a hydraulic additive, a cement activator, and sand;
- and
- then mixing water with the mixture to form a cured hybrid magnesium cement (HMC) composition.
A process for forming a cured hybrid magnesium cement (HMC) composition, the process comprising:
- combining together a mixture of magnesium-containing material, a metal silicate inorganic polymer having a repeat unit of SiP2O7, and a salt having a non-metallic oxide anion;
- mixing the mixture with water;
- adding a linear silicon polymer including at least one silicone resin polymer comprising a siloxane-oxygen structure R—SiO, where R represents alkyl and aryl organic groups, wherein the R—SiO siloxane-oxygen resin polymer ranges from 0.03 wgt. % to 5 wgt. % and contains at least 40 wgt. % SiO2, where the R represents a phenol:methyl ratio of 0.6:1, a molecular weight of <5,000 daltons and a Tg between 40° C. and 70° C.
