Coral aggregate modification method and modified coral aggregate vegetation concrete
The invention discloses a coral aggregate modification method and modified coral aggregate vegetation concrete.The coral aggregate modification method comprises the following steps that coral aggregate is soaked in a mixed solution of sodium dihydrogen phosphate and oxalic acid for 12-24 h, the coral aggregate is aired after being soaked, and the modified coral aggregate can be obtained. The vegetation concrete is prepared from the following raw materials in parts by mass: 1000 to 1200 parts of modified coral aggregate, 400 to 500 parts of Portland cement, 10 to 15 parts of rice hull ash, 8 to 15 parts of diatomite and 150 to 180 parts of water. The coral is used for replacing aggregate required by the vegetation concrete, so that rich marine resources in China can be fully utilized, and the dilemma that natural aggregate is deficient is relieved. The coral aggregate is pretreated by utilizing the property that the water absorption rate of the coral aggregate is high so as to reduce the pH value of the coral aggregate vegetation concrete, and the rice hull ash and the diatomite are added, so that the performance and the strength of the coral aggregate vegetation concrete are improved, and the coral aggregate vegetation concrete can adapt to plant growth and simultaneously has the functions of structural protection and ecological protection.
本发明公开了一种珊瑚骨料改性方法及改性珊瑚骨料植生混凝土，所述珊瑚骨料改性步骤如下：将珊瑚骨料浸泡在磷酸二氢钠与草酸混合溶液中，浸泡时间为12‑24h，浸泡后晾干，即可得改性珊瑚骨料。所述植生混凝土以质量份数计，包括如下原料：改性珊瑚骨料1000‑1200份，硅酸盐水泥400‑500份，稻壳灰10‑15份，硅藻土8‑15份，水150‑180份。本发明利用珊瑚替代植生混凝土所需骨料，能充分利用我国丰富的海洋资源，缓解天然骨料匮乏的困境。利用珊瑚骨料自身吸水率高的性质，对其进行预处理，以降低珊瑚骨料植生混凝土的pH值，通过稻壳灰、硅藻土的加入，改善珊瑚骨料植生混凝土性能，提高强度，达到能适应植物生长，同时兼顾结构防护和生态保护的功能。
