The invention relates to a high-ductility cement-based artificial stone. The artificial stone is prepared from, by weight, 20.0-25.0 parts of Portland cement, 30-40 parts of quartz sand of 60 to 80 meshes, 20-30 parts of quartz sand of 80 to 120 meshes, 15.0-20.0 parts of industrial waste residue, 8-12 parts of latex powder, 0.5-1.5 parts of pva fiber, 0.5-1.5 parts of glass fiber, 0.01-0.02 part of a defoaming agent, and 7-10 parts of water. The artificial stone has the beneficial effects of good toughness, drop resistance, collision resistance, good appearance quality, no macropore, no color difference, no saltpetering in a common environment, small later shrinkage and difficult deformation of the plate, and by polymer modification and addition of a high doping amount of redispersible latex powder into the material, the toughness of the material is improved, and the material is endowed with a certain degree of deformability; and the artificial stone product has extremely high toughness and is resistant to falling and bumping.
本发明涉及一种高延性水泥基人造石，由如下重量份的原料制备而成：硅酸盐水泥20.0份～25.0份；60‑80目石英砂30‑40份；80‑120目石英砂20‑30份；工业废渣15.0份～20.0份；乳胶粉8‑12份；pva纤维0.5份～1.5份；玻纤0.5份～1.5份；消泡剂0.01份～0.02份；水7份～10份。有益效果是：韧性好，抗摔抗磕碰，外观质量好，无宏观气孔无色差，普通环境中不泛碱，后期收缩小，板材不易变形，通过聚合物改性，材料中添加较高掺量的可再分散性乳胶粉，提升材料的韧性，赋予材料一定程度的变形能力；人造石产品拥有极高的韧性，具有抗摔抗磕碰。
