High-strength composite fiber expansion anti-cracking agent and preparation process thereof
The invention relates to the technical field of concrete additives, and provides a high-strength composite fiber expansion anti-cracking agent and a preparation process thereof. The high-strength composite fiber expansion anti-cracking agent comprises, by mass, no less than 40% of a CaO-MgO-Al2O3-SO3 expansion source, no less than 25% of fibrous aggregate mineral powder and no less than 18% of modified fiber-doped polymer sol liquid. According to the invention, the physical and chemical properties of the composite fiber expansion anti-cracking agent are effectively improved through reasonable selection and matching of the raw materials, modification treatment and optimization of preparation steps, a doping amount is reduced, excellent compressive strength and an excellent expansion rate in a restrict condition are obtained, and high comprehensive practicability is achieved.
本发明涉及混凝土添加剂技术领域，提出了一种高强度复合纤维膨胀抗裂剂及其制备工艺，包括CaO‑MgO‑Al2O3‑SO3膨胀源、纤维状集合体矿石粉、改性纤维掺杂高分子溶胶液，其中，以质量百分含量计，CaO‑MgO‑Al2O3‑SO3膨胀源≥40%、纤维状集合体矿石粉≥25%、改性纤维掺杂高分子溶胶液≥18%，本发明通过对原料的合理选配、改性处理以及制备步骤的优化，有效提高了纤维抗裂膨胀剂的物化性能，不仅掺量减少，而且具有优异的抗压强度和限制膨胀率，综合实用性强。
