The invention relates to a concrete viscosity modifier as well as a preparation method and application thereof, and the concrete viscosity modifier comprises the following raw materials in percentage by mass: 27%-45% of modified hemp stalk viscose fiber powder, 29%-53% of biomass powder, 7%-15% of silica fume and 10%-20% of fly ash, the modified hemp stalk viscose fiber powder is obtained by sequentially carrying out hydrothermal treatment, alkali treatment, drying and crushing treatment on hemp stalk viscose fibers. The viscosity of the concrete can be greatly improved by using the biomass powder, the concrete has the rapid thickening and tackifying capacity, the water retention capacity of the concrete can be greatly improved by using the modified hemp stalk viscose fiber powder, and when the biomass powder and the modified hemp stalk viscose fiber powder are jointly used, the viscosity of the concrete can be greatly improved. The biomass powder and the modified hemp stalk viscose fiber powder are filled in gaps among concrete particles after absorbing water and expanding, so that the rapid thickening and tackifying capability and the water retention capability of the concrete can be further improved.
本发明涉及一种混凝土黏度调节剂及其制备方法和应用，包括以下质量百分比的原料：包括以下质量百分比的原料：改性汉麻秆粘胶纤维粉末27％～45％、生物质粉29％～53％、硅灰7％～15％、粉煤灰10％～20％，其中，改性汉麻秆粘胶纤维粉末为汉麻秆粘胶纤维依次经水热处理、碱处理、干燥和粉碎处理后获得。本发明通过生物质粉的使用可较大程度地提高混凝土的黏度，令混凝土具有快速增稠增粘的能力，改性汉麻秆粘胶纤维粉末的使用可以较大程度地提高混凝土的保水能力，且当生物质粉与改性汉麻秆粘胶纤维粉末共同使用的时候，生物质粉和改性汉麻秆粘胶纤维粉末在吸水膨胀后填充于混凝土颗粒之间的间隙中，可更进一步地提高混凝土快速增稠增粘的能力、保水能力。
