The purpose of the present invention is to provide a preceding material for pumping, a feeding of a very small amount thereof being capable of extending the pumping distance. The preceding material for pumping includes an added cellulose nanofiber and having calcium carbonate as a main component. The present invention enables a thin lubricant layer of a uniform thickness to be formed inside a pipe even when the pipe has a slightly roughened inner surface due to, for example, residues of solidified cement paste or the like, allowing the pumping distance to be extended. Thus, the present invention is suitable, for example, for casting ready-mixed concrete at various construction sites.

The invention relates to a composition for building construction comprising a paper sludge deriving from de-inked paper recycling processes, the sludge having a grain size distribution D90 in the range of 30 to 1000 m and an ingredient selected from the group consisting of modified cellulose, cement, furnace slag and mixtures thereof.

The embodiments herein are directed to dry wall waste mixtures, formed under pressure into example embodiments referred to herein as dry wall waste blocks (DWBs) and/or gypsum wallboard waste blocks (GWWBs) and tile structures. DWBs/GWWBs mixtures in particular, often incorporate a higher percentage in the composite mixtures from about 60% up to 85% of dry wall waste than other mixtures and beneficially often incorporates substantially all of the wallboard facing paper as part of the composite mixture. That is, waste processing is simplified by comingling core and paper layers in the final product. DWBs/GWWBs mixtures utilize demolition and construction waste, replacing a high percentage of Portland cement with waste-derived binder.

A method of decreasing the water load needed to form a fibrous panel. The process includes admixing a mineral wool, a cellulose, and a binder to provide a pre-mixed slurry, admixing a mineral filler with water to provide a mineral filler slurry, admixing the pre-mixed slurry and the mineral filler slurry to form a dispersion, flowing the dispersion onto a foraminous support wire to provide a green board, dewatering the green board to form a dewatered green board and drying the dewatered green board to provide a fibrous panel.
