The invention relates to the technical field of precast concrete components, discloses precast concrete component exposed aggregate and solves the problems that exposed aggregate in the prior art hascomplex ingredients, high production cost and high selling price. The precast concrete component exposed aggregate is prepared from the following raw materials in mass percent: 7.5% to 10% of sodium gluconate, 0.8% to 1.2% of thickening agent, 0.1% to 0.5% of preservative and 88.3% to 91.6% of water, wherein the raw materials are evenly mixed to prepare the precast concrete component exposed aggregate. The precast concrete component exposed aggregate has the advantages of simple ingredients, low cost, easiness in being painted, no fluidity and good use effect. The invention further discloses apreparation method of the exposed aggregate. All the ingredients are mixed according to steps to obtain a finished product of the exposed aggregate, and the preparation method is simple. 本发明涉及混凝土预制构件技术领域，公开了种混凝土预制构件的露骨料；解决了现有
