Self-waterproof concrete and preparation method thereof
The invention belongs to the technical field of building materials, and particularly relates to self-waterproof concrete and a preparation method thereof. The self-waterproof concrete provided by theinvention is mainly prepared from Portland cement, gravel, sand, modified wood ceramic, 2-acrylamido-2-methylpropanesulfonic acid, sodium lignosulfonate and water. The self-waterproof concrete prepared by the invention has the characteristics of high strength and high hardness, can greatly enhance the compression resistance and crack resistance of the concrete. The cracking phenomenon caused by factors such as large specific surface of basement outer wall, quickly dissipating of water on surface of basement outer wall, uneven stress of the lower and upper parts in the outer wall concrete hardening process and temperature difference between the interior and exterior of the concrete is solved; meanwhile, the self-waterproof function is very strong, and the durability and the safety of the concrete member can be effectively improved.
本发明属于建筑材料技术领域，具体涉及一种自防水混凝土及其制备方法。本发明提供的自防水混凝土主要由硅酸盐水泥、碎石、砂、改性木陶瓷、2‑丙烯酰胺基‑2‑甲基丙磺酸、木质素磺酸钠和水组成。本发明制得的自防水混凝土具有强度高和硬度高的特点，可以大大提高混凝土的抗压和抗裂能力，可以解决地下室外墙因比表面大、表面水分散发较快，外墙混凝土硬化过程中下上部受力不均和混凝土内外部温度差等因素而导致开裂的现象；同时还具有很强的自防水功能，可以有效的提高混凝土构件的耐久性和安全性。
