Preparation method of modified waste rubber pervious concrete and concrete
The invention relates to a preparation method of modified waste rubber pervious concrete and concrete.The preparation method comprises the steps that coarse aggregate, fine aggregate, cement, water, modified waste rubber powder, sodium laurate powder, silica fume, a water reducing agent and a thickening agent are evenly mixed to prepare the pervious concrete, and the modified waste rubber powder is modified through tannic acid; the method comprises the following steps: adding 20-40 parts by mass of unmodified waste rubber powder into 100-200 parts by mass of water, uniformly stirring, adding 1-2 parts by mass of a tannic acid solution, stirring, filtering out the waste rubber powder, cleaning with deionized water, filtering out the waste rubber powder cleaned with deionized water, and drying to obtain the modified waste rubber powder. The tannic acid is used for modifying the waste rubber, and the sodium laurate powder is matched, so that the compressive strength and fracture resistance of the prepared pervious concrete are improved.
本发明涉及一种改性废弃橡胶透水混凝土制备方法及混凝土，将粗骨料、细骨料、水泥、水、改性废弃橡胶粉、月桂酸钠粉、硅灰、减水剂、增稠剂混合均匀制备得到透水混凝土，改性废弃橡胶粉通过单宁酸进行改性，改性时按照质量份数比将20‑40份未改性的废弃橡胶粉加入100‑200份水中搅拌均匀，然后加入1‑2份单宁酸溶液搅拌后，将废弃橡胶粉滤出并通过去离子水清洗，然后再将去离子水清洗后的废弃橡胶粉滤出干燥得到改性废弃橡胶粉。本发明通过单宁酸对废弃的橡胶进行改性，配合月桂酸钠粉使得制备得到的透水混凝土的抗压强行和抗折性能得以提升。
