The invention relates to the technical field of concrete, and discloses cement concrete with high crack resistance and a production method thereof, the cement concrete comprises the following raw materials: cement, sand, broken stone, fly ash, silica fume, agarose aerogel, a modified fiber component and water; wherein the agarose aerogel is prepared by introducing a carboxyl group and a sulfonic acid group into an agarose structure, so that the mechanical property and the crack resistance of the concrete are effectively improved; according to the modified fiber component, polyamide-amine is grafted to the surface of palm fiber in a chemical connection mode, the binding force of the palm fiber and a cement hydration product is improved, cement particles are tightly adsorbed to the surface of the palm fiber, and therefore the prepared concrete has the good mechanical property and the good anti-cracking effect; the method can be widely applied to various engineering constructions.
本发明涉及混凝土技术领域，公开了一种具有高抗裂功能性的水泥混凝土及其生产方法，该水泥混凝土包括以下原料：水泥、砂、碎石、粉煤灰、硅灰、琼脂糖气凝胶、改性纤维组分、水；其中琼脂糖气凝胶是通过在琼脂糖的结构中引入羧基基团和磺酸基团，有效提高了混凝土的力学性能和抗裂性能；改性纤维组分是通过利用化学连接的方式，将聚酰胺‑胺接枝到棕榈纤维的表面，提高了棕榈纤维与水泥水化产物的结合力，使水泥颗粒紧密吸附在棕榈纤维的表面，从而使制备的混凝土具有良好的力学性能和抗裂效果，可以被广泛应用于各类工程建设中。
