摘要： Provided is an inorganic solid waste-microbial composite curing agent and its preparation method and application. The inorganic solid waste-microbial composite curing agent consists of the following raw materials in parts by weight: steel slag, active magnesium oxide, recycled powder, stearic acid, borax, carbonic anhydrase bacteria, Bacillus subtilis, and soluble calcium salts. The preparation method includes performing granulation on steel slag, active magnesium oxide, recycled powder, stearic acid, borax, etc. into porous materials through dry rolling extrusion and compression, and loading carbonic anhydrase bacteria and Bacillus subtilis into the porous materials. By adding inorganic solid waste-microbial composite curing agent into the sludge and introducing CO2, the sludge is quickly solidified through the carbonization and microbial mineralization of inorganic solid waste. At the same time, microorganisms can effectively decompose organic pollutants in the sludge, achieving the goal of harmless, stabilized and resourceful utilization of sludge.

摘要： The present disclosure relates to methods that transform high salinity brine into a non-toxic, CO2-absorbing cementitious aggregate composition and a lower salinity water component which can each be recycled to the desalination facility, further processed to produce fresh water, and/or added to a body of water and without harming the local flora and fauna. The present disclosure provides methods comprising steps of: (a) combining (i) a high salinity brine, (ii) CO2, and (iii) a pozzolan and/or a latently hydraulic material; and (b) permitting the combination obtained in step (a) to persist under conditions sufficient to transform the combination into a cementitious aggregate composition and a reduced salinity water component. In some case, an activator, as disclosed herein, is added to the combination. The present disclosure further a cementitious aggregate compositions and shaped cementitious compositions, each obtained by herein-disclosed methods.

摘要： A method of preparation of a construction element by carbonation, includes a) preparing a composition containing a cement, water and chemical additives; b) pre-drying the composition; then c) placing the pre-dried composition in a chamber of an incubator, the chamber containing at least one inlet and one outlet, the pre-dried composition being carbonated, in a carbonation procedure, by feeding into the chamber, through the inlet, a flow of CO2 containing gas, variations of the CO2 concentration in the chamber being kept below 10% of a reference value during the whole carbonation procedure, during the carbonation procedure, the pressure within the chamber being atmospheric pressure, the relative humidity within the chamber being above 80° % and the temperature within the chamber ranging from 20° C. to 80° C. The chemical additives in the composition include more than 0.05% in weight, compared to the total weight of the cement, of a cement hydration retarder.

摘要： A bio-composite plastering material and a method of making the same are provided. The bio-composite plastering material includes a mixture of sand-silica, Abelmoschus esculentus powder, and multi-walled carbon nanotubes. The bio-composite plastering material has increased compressive strength depending upon the concentration of Abelmoschus esculentus powder and multi-walled carbon nanotubes used. The method of making the bio-composite plastering material includes sieving the sand-silica to produce sand-silica of a uniform particle size, mixing powdered Abelmoschus esculentus powder with the sand-silica to produce a first mixture, mixing water with the first mixture to produce the bio-composite plastering material, and enhancing the bio-composite material by adding multi-walled carbon nanotubes. The bio-composite plastering material may then be plaster cast, such as by pressing the bio-composite plastering material in a hot press and drying the resulting bio-composite material in an oven.

摘要： A method for preparing low-background cement includes: uniformly mixing a seed crystal of cement, C4AF whiskers, and high-magnesium raw material to yield a first mixture, calcining the first mixture at 1400-1500° C., to yield a low-background clinker, the first mixture including 1.0-5.0 wt. % of the seed crystal of cement, 1.0-5.0 wt. % of the C4AF whiskers, and the balance is the high-magnesium raw material; and grinding a second mixture of the low-background clinker and gypsum, to yield low-background cement. The seed crystal of cement is a high-magnesium and low hydration heat clinker, has a specific activity of Ra-226 radioactive nuclides within 50 Bq/kg, and the MgO content of the clinker is between 4.0 wt. % and 5.0 wt. %, with 50 wt. %≤C3S≤55.0 wt. %; and the high-magnesium raw material has a MgO content between 2.5 wt. % and 3.0 wt. %.
