Environment-friendly admixture for concrete and preparation method thereof
The invention discloses an environment-friendly admixture for concrete and a preparation method thereof. The preparation method of the environment-friendly admixture for concrete comprises the following steps: uniformly mixing 5-10 parts of a water-retaining agent, 3-6 parts of a shrinkage reducing agent, 40-60 parts of a waste paper abrasive, 10-17 parts of a mulberry leaf extract and 4-6 parts of modified carbon nanofibers, and bagging for later use as a solid component; independently packaging 20-35 parts of the modified water reducing agent as a liquid component; when in use, the solid component and the liquid component are added into concrete. According to the additive disclosed by the invention, through the synergistic effect of the components of the modified water reducing agent, the water-retaining agent, the waste paper abrasive, the mulberry leaf extract, the modified carbon nanofiber and the shrinkage reducing agent, the setting time of concrete is adjusted, the slump loss is reduced, and the durability, strength, crack resistance and carbonization resistance of the concrete are improved.
本发明公开了混凝土用环保外加剂及其制备方法。所述混凝土用环保外加剂的制备方法，包括以下步骤：将5‑10份保水剂、3‑6份减缩剂、40‑60份废纸研磨料、10‑17份桑叶提取物、4‑6份改性碳纳米纤维混合均匀，装袋备用，作为固体成分；将20‑35份改性减水剂单独包装，作为液体成分；使用时将固体成分与液体成分加入混凝土中即可。本发明的外加剂通过改性减水剂、保水剂、废纸研磨料、桑叶提取物、改性碳纳米纤维、减缩剂的各组分协同作用，调整混凝土的凝固时间、减少坍落度损失，增加混凝土耐久性、强度、抗裂性以及抗碳化能力。
