摘要： 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.

摘要： It is an object of the present invention to provide a resin composite that is excellent in water resistance and is capable of exerting sufficient strength even under wet conditions. The present invention relates to a resin composite comprising a resin, fibers having an ionic functional group, and a polyvalent ion. The fibers having an ionic functional group are preferably cellulose fibers having a fiber width of 1000 nm or less.
