High-strength rubber concrete and preparation method thereof
The high-strength rubber concrete is prepared from the following raw materials in parts by weight: 27 to 32 parts of cement, 11 to 13 parts of blast furnace slag powder, 6 to 9 parts of fly ash, 70 to 80 parts of fine aggregate, 2 to 5 parts of modified rubber particles, 94 to 101 parts of coarse aggregate, 0.4 to 0.5 part of water reducing agent, 0.08 to 0.25 part of anti-freezing agent, 0.03 to 0.1 part of early strength agent and 15 to 16 parts of water. The raw materials for preparing the concrete are subjected to low-temperature treatment, stirred and formed under the low-temperature condition and then subjected to standard curing, the thermal expansion coefficient of cement stone is smaller than that of modified rubber particles, and the volume expansion degree of the rubber particles is larger than that of particle cement stone shells, so that the range of an interface transition area is reduced; and in the later continuous hydration process, due to the internal stress generated by non-uniform expansion, the interface transition area is denser in the hydration process, the compaction and maintenance effects are achieved, and the strength of the interface transition area is improved.
本发明公开了一种高强橡胶混凝土，包括如下重量份数的原料：水泥27‑32份、高炉矿渣粉11‑13份、粉煤灰6‑9份、细骨料70‑80份、改性橡胶颗粒2‑5份、粗骨料94‑101份、减水剂0.4‑0.5份、防冻剂0.08‑0.25份、早强剂0.03‑0.1份和水15‑16份。本发明通过将制备混凝土的原材料进行低温处理并低温条件下进行搅拌成型后再进行标准养护，由于水泥石的热膨胀系数小于改性橡胶颗粒的热膨胀系数，橡胶颗粒体积膨胀程度大于颗粒水泥石外壳，使得界面过渡区范围减小，而且在后期持续水化过程中，由于不均匀膨胀产生的内应力使得在水化过程中界面过渡区更加密实，起到压实养护的效果，提高了界面过渡区强度。
