The invention relates to the technical field of clay bricks, and discloses a compact clay brick and a preparation method thereof, the compact clay brick comprises 100 parts by weight of soft clay, 25-40 parts by weight of red mud, 20-32 parts by weight of fly ash, 4-8 parts by weight of a sulfurous acid paper pulp waste liquid binder, and 0.1-0.6 part by weight of modified carbon fiber; the surface of the modified carbon fiber contains a large number of biquaternary ammonium salt cation structures which can generate electrostatic interaction with anions on the surface of clay, so that the interface bonding performance between the carbon fiber and the clay is enhanced, the interior of the clay brick is tighter, the volume density and compactness of the clay brick are improved, the water absorption rate is reduced, and the water resistance and water resistance are improved. And the carbon fiber has the advantages of high strength, high modulus and strong compressive property, and the interface bonding property between the modified carbon fiber and the clay is better, so that the compressive strength and breaking strength of the clay brick are improved.
本发明涉及粘土砖技术领域，且公开了一种致密粘土砖及其制备方法，致密粘土砖包括100重量份软质粘土、25‑40重量份赤泥、20‑32重量份粉煤灰、4‑8重量份亚硫酸纸浆废液结合剂、0.1‑0.6重量份改性碳纤维；改性碳纤维表面含有大量的双季铵盐阳离子结构，可以与粘土表面的阴离子发生静电相互作用，增强碳纤维与粘土之间的界面粘结性能，使粘土砖内部更加紧密，从而提高粘土砖的体积密度和致密性，有利于降低吸水率，提高耐水防水性能。并且碳纤维具有强度大，模量高，抗压性能强，改性后的碳纤维与粘土之间的界面结合性能更好，提高了粘土砖的耐压强度和抗折强度。
