Provided is fibrous cellulose used for producing a concrete-pump pressure-feeding primer containing calcium carbonate powder, which is excellent in a dispersion stability and a pressure-feeding property. The fibrous cellulose is used for producing the concrete-pump pressure-feeding primer through mixing with the calcium carbonate powder. The fibrous cellulose contains ultrafine fibrous modified cellulose which has an ionic group and has a fiber width of 1,000 nm or less.

A device and method for reinforcing recycled aggregate based on in-situ C—S—H production including a first, second, third chamber, and a blast drier. A spray structure arranged on the top of the third chamber; the first and second chamber connected to the spray structure through pumps. A hollowed container arranged at the bottom of the spray structure. A certain gap reserved between the bottom of the container and the bottom of the third chamber, the bottom of the third chamber is provided with at least one drain outlet; the blast drier connected to the bottom of the third chamber, and a cover is arranged on the top of the third chamber. The first chamber contains calcium hydroxide solution. The second chamber contains a mixed solution of TEOS, water and anhydrous ethanol. The container is arranged in the third chamber, and the container is used to contain to-be-treated recycled aggregate.

This disclosure provides electron beam irradiated products and methods thereof. In particular, the invention is directed to a products and methods that comprise an electron beam irradiated component and a second component. The electron beam irradiated component may be plastic. The second component may be a building material or construction material. The invention is also directed to methods of manufacturing a modified polymer material with an electron-beam. Methods comprise irradiating the polymer particles of the material by dosing with electron beam radiation to produce a modified polymer material comprising irradiated polymer particles.
