The invention discloses a low-carbon building material, which is characterized by comprising the following raw materials: river sand or mineral residue as aggregate, cation modified micro-nano waste paper fiber and silica sol. According to the invention, the surface of the waste paper fiber is positively charged through cation modification, and the waste paper fiber and the siliceous aggregate with negatively charged surface generate an electrostatic adsorption effect, so that the fiber-aggregate interface bonding force is remarkably enhanced. The addition of the silica sol further promotes the cross-linking reaction of aggregate-fiber to form a stable network structure. In the preparation process, cement clinker, high-temperature sintering or high-pressure curing are not needed, forming can be performed at normal temperature and normal pressure, resource utilization of waste is achieved, carbon emission is remarkably reduced, and meanwhile cement is replaced.

The application provides a hectorite-polymer large-temperature-difference constant-flow rheological modifier and a preparation method and application thereof. The rheological modifier comprises the following raw materials in parts by weight: 2-5 parts of nano hectorite, 4-10 parts of a silane coupling agent, 8-12 parts of a monomer containing an adsorption group, 10-15 parts of an anionic monomer, 5-8 parts of a cationic monomer, 2-5 parts of a temperature-sensitive monomer and 0.14-0.18 parts of an initiator.
