摘要： A process involves adding charged fibers with surface-cured “temperature-sensitive gel” during the preparation of concrete; preparing charged fibers with surface-cured “temperature-sensitive gel” by spraying, which envelops the charged fibers with a layer of “temperature-sensitive gel”; then solidifying the temperature-sensitive gel layer on the surface of the charged fibers by adjusting the environmental temperature. Utilizing the physical state of the temperature-sensitive gel at different temperatures, the “temperature-sensitive gel” wraps around the charged fibers to form an insulating layer. This prevents the scattering of the charged fibers due to charge repulsion during their introduction into the concrete preparation process, ensuring they are evenly distributed.

摘要： A method of manufacturing a catalytic fuel brick includes providing a metal-based cementing agent including magnetite, an aqueous phosphoric acid cement reacting agent, and an aggregate including at least one of coal, grain biomass and wood biomass. The catalytic fuel brick further includes a setting agent of at least one of iron oxide and iron. The constituent components of the catalytic fuel brick are mixed together to form a liquid concrete mixture, which is placed in a form and allowed to set up and cure into the catalytic fuel brick. The method can optionally include the additional step of placing the concrete product into an oven at a temperature of between 170 and 190 C.

摘要： Disclosed herein are a fly ash-based foam geopolymer, a preparation method therefor, and the use thereof. The fly ash-based foam geopolymer is prepared from raw materials comprising the following components in parts by weight: 900-1000 parts of a fly ash-based material; 600-700 parts of a composite alkali solution; 0-10 parts of a thickening agent; 2-6 parts of a foam stabilizer A; 5-10 parts of a water reducer; and 20-40 parts of a foaming agent. The preparation method of the present application is simple, and processes such as ball milling, water washing and calcining do not need to be carried out on the raw materials, such that the investment in a grinding equipment, a water washing equipment, a sewage treatment equipment, and a calcining equipment is reduced, and the energy consumption and carbon emissions are reduced. The fly ash-based foam geopolymer prepared by using the fly ash-based material as the main raw material in the present application has a low apparent density and a high early strength, and can be used in the field of fabricated buildings.

摘要： Reinforced concrete is protected from corrosion without conducting an operation involving exposure of rebar. A reinforced concrete structure is provided with a storage part that is formed inside concrete of the reinforced concrete structure, and that retains an anticorrosion solution. The anticorrosion solution diffuses and permeates through the concrete from the storage part, prevents the concrete in the vicinity of rebar from drying, and passivates the rebar.
