Sea sand coarse aggregate modification method and application of sea sand coarse aggregate in vegetation concrete
The invention discloses a sea sand coarse aggregate modification method and application of the sea sand coarse aggregate in vegetation concrete.The modified sea sand coarse aggregate is prepared by the steps that 5-5.34 parts of sea sand, 2-2.12 parts of red mud, 1.5-1.72 parts of cement and 0.54-0.86 part of waste incineration bottom ash are added into a disc of a ball forming mill, and a machine is started for stirring so that solid materials can be fully and evenly mixed; and spraying 0.86-1.04 parts of water onto the material at a constant speed, and stirring to obtain the modified sea sand coarse aggregate. The vegetation concrete is prepared from the following raw materials in parts by mass: 180 to 210 parts of cement, 50 to 70 parts of bagasse ash, 1080 to 1180 parts of modified sea sand coarse aggregate and 140 to 150 parts of water. The red mud, the cement, the waste incineration bottom ash and the water are added into the sea sand coarse aggregate for modification treatment, and the cement, the bagasse ash and the water are added into the obtained modified sea sand coarse aggregate to prepare the vegetation concrete, so that the micro-aggregate effect, the filling effect and the plant fertilizer efficiency of the red mud, the waste incineration bottom ash and the bagasse ash in industrial and agricultural byproducts can be fully utilized; the cost is low, but the good physical property and durability are achieved, and the plant growth can be adapted.
本发明公开了一种海砂粗骨料改性方法及其在植生混凝土的应用，所述改性海砂粗骨料是将5‑5.34份海砂、2‑2.12份赤泥、1.5‑1.72份水泥、0.54‑0.86份垃圾焚烧底灰加入到成球机圆盘中，开动机器搅拌使固体物料充分混合均匀；将0.86‑1.04份的水匀速喷洒到物料上，搅拌，得到改性海砂粗骨料。所述植生混凝土由以下质量分数的原料制成：水泥180～210份、蔗渣灰50～70份、改性海砂粗骨料1080～1180份、水140～150份。本发明海砂粗骨料中加入赤泥、水泥、垃圾焚烧底灰和水进行改性处理，得到的改性海砂粗骨料再加入水泥、蔗渣灰和水以制备植生混凝土，能够充分利用工农业副产品中赤泥、垃圾燃烧底灰和蔗渣灰的微集料效应、填充效应和植物肥效，成本低廉但却具有较好的物理性能和耐久性，能适应植物生长。
