The invention belongs to the field of concrete additives, and particularly relates to a waterproof and anti-freezing additive for mortar and concrete and a preparation method thereof. The waterproof and anti-freezing additive is prepared from the following components in percentage by mass: 30 to 50 percent of a pore blocking component, 30 to 60 percent of a volcanic ash active component and 10 to25 percent of a seed crystal component, the pore blocking component is selected from one or two of hydrophobically modified iron oxide and hydrophobically modified mica; wherein the volcanic ash active component is selected from one or more than two of hydrophobically modified metakaolin, hydrophobically modified wollastonite and hydrophobically modified diatomite; the seed crystal component is hydrophobically modified silicon dioxide. The waterproof and anti-freezing additive can effectively prevent water from entering channels of mortar and concrete, improve the compactness of the mortar andthe concrete, and can remarkably prolong the service life of the mortar and the concrete.
本发明属于混凝土添加剂领域，具体涉及一种砂浆、混凝土防水抗冻添加剂及其制备方法。该防水抗冻添加剂由以下质量百分比的组分组成：孔隙阻断组分30‑50％，火山灰活性组分30‑60％，晶种组分10‑25％；所述孔隙阻断组分选自疏水改性的氧化铁、疏水改性的云母中的一种或两种；所述火山灰活性组分选自疏水改性的偏高岭土、疏水改性的硅灰石、疏水改性的硅藻土中的一种或两种以上；所述晶种组分为疏水改性的二氧化硅。该防水抗冻添加剂有效阻断了水进入砂浆、混凝土的通道，增加了砂浆、混凝土的密实性，能够显著的延长砂浆、混凝土的工作寿命。
