▎ 摘　　要

NOVELTY - The method involves (a) dissolving polycarboxylic acid water reducing agent in distilled water, adding acetonitrile and stirring, (b) adding natural gravel, steel slag, river sand, iron tailings sand, cement, fly ash and expansion agent into a stirrer, drying and stirring and adding water to stir, (c) adding graphene and carbon nanotubes powder into the solution, stirring, allowing to stand, placing the suspension in the ice water mixture environment and using an ultrasonic instrument to prepare an acetitrile-carbon nano tube graphene dispersion liquid, (d) adding the prepared acetonamide-carbon nano tube-dispersion graphene into the stirrer to continue to stir, (e) discharging the stirred mixture, pouring on the pre-placed steel plate, measuring the slump and pouring, (f) after forming the test piece, numbering, dismounting the mold and moving into the curing box, and (g) when reaching the regular age, taking out the concrete test piece from the curing box, preparing and forming. USE - The method is useful for preparing green reinforced body modified concrete. ADVANTAGE - The green reinforced body modified concrete has good quality, simple preparation technique and is suitable for large area popularization and application. The acetonitrile has excellent solvent performance, can be used for preparing excellent dissolving environment, the carbon nano tube can improve the tensile strength of the material, compression strength can effectively improve the dispersion degree of the mixed material under the synergistic effect of the aconetitrile-carbon nano tube-graphene, optimizing the pore structure of the grouting material and effectively improving the mechanical property, the liquid environment solution configured by the three can effectively enhance the modification of the concrete and promotes the hydration reaction to reduce the bigger capillary hole in the cement-base material to generate smaller gel-hole. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for a green reinforced body modified concrete, is prepared as mentioned above.
