Abstract
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.
