Modifier and cementing material
The invention provides a modifier and a cementing material, and belongs to the field of building materials. The invention provides a modifier, which is prepared from the following components in parts by mass: 0.3 to 0.7 part of mineral powder; 0.13 to 0.3 part of steel slag powder; 0.1 to 0.7 part of calcium sulfate whisker; 0 to 0.2 part of barium sulfate; and 0.1 to 0.21 part of a fiber suspending agent. The steel slag powder can provide Ca < 2 + > lacking in the hydration process of the cementing material and continuously generate C-S-(A)-H gel, and the C-S-(A)-H gel can be bonded with the whiskers, so that the integrity of the cementing material is improved, and the crack resistance and toughness are improved; sO4 < 2-> dissolved from the mineral powder and the desulfurized gypsum can induce the calcium-rich layer to quickly absorb water and dissolve, so that the structure of the cementing material is denser, and the bearing capacity and compressive strength of the cementing material are improved; the calcium sulfate can effectively reduce the destructive effect of external force impact and improve the compressive strength of the cementing material.
本发明提供了一种改性剂、胶凝材料，属于建筑材料领域。本发明提供了一种改性剂，以质量份数计，包括以下组分：矿粉0.3～0.7份；钢渣粉0.13～0.3份；硫酸钙晶须0.1～0.7份；硫酸钡0～0.2份；纤维悬浮剂0.1～0.21份。本发明中钢渣粉能提供胶凝材料水化过程中缺少的Ca2+，不断生成C‑S‑(A)‑H凝胶，并且C‑S‑(A)‑H凝胶可与晶须发生黏结，使得胶凝材料的整体性得到提高，从而提高了抗裂性能和韧性；矿粉和脱硫石膏溶出的SO42‑可诱导富钙层迅速吸水溶解，使得胶凝材料结构更密实，从而提高了胶凝材料的承载能力和抗压强度；硫酸钙能有效降低外力冲击的破坏作用，提高胶凝材料的抗压强度。
