The invention provides a calcareous sand modifier and a preparation method thereof. The calcareous sand modifier comprises the following raw materials in parts by weight: 0.3 to 0.4 part of nano clay, 1 to 2 parts of nano magnesium oxide, 1.5 to 1.8 parts of nano graphdiyne, 0.1 to 0.2 part of coconut fibers, 0.4 to 0.5 part of banana fibers and 2 to 3 parts of methyl cellulose. By adopting the calcareous sand modifier disclosed by the invention, the compressive strength and shear strength of the modified calcareous sand are remarkably improved on the basis of using a small amount of modifier, the requirements of the modifier on storage space and transport capacity are effectively reduced, and the modifier is better applied to modification of the calcareous sand.
本发明提供一种钙质砂改性剂及其制备方法，所述钙质砂改性剂包括以下重量份原料：纳米粘土0.3～0.4份、纳米氧化镁1～2份、纳米石墨炔1.5～1.8份、椰壳纤维0.1～0.2份、香蕉纤维0.4～0.5份、甲基纤维素2～3份。采用本发明钙质砂改性剂，在使用较少改进剂的基础上，改性后钙质砂的抗压强度和抗剪强度有显著提升，有效降低改性剂对储存空间、运力要求，更好应用于钙质砂改性。
