Novel island reef rapid repair concrete
The invention discloses novel island reef rapid repair concrete, belongs to the technical field of adding additives into concrete, and is realized on the basis of sulphoaluminate cement with rapid solidification performance and anti-dispersing agent xanthan gum. The concrete is prepared from coral reef sand powder with the particle size of 1-3mm, coral aggregate with the particle size of 10-15mm,a superplasticizer and sulphoaluminate cement. The concrete disclosed by the invention has the characteristic of rapid solidification, has excellent underwater dispersion resistance, and is low in relative cost which cannot be achieved by other underwater concrete in island construction.
一种新型岛礁快速抢修混凝土，属于将外加剂添加入混凝土的技术领域，是基于拥有快速凝固性能的硫铝酸盐水泥和抗分散剂黄原胶来实现。所述混凝土包括粒径为1‑3mm的珊瑚礁砂粉末，10‑15mm的珊瑚骨料，高效减水剂和硫铝酸盐水泥构成。本发明具有快速凝固的特性，并且具有优异的水下抗分散性，相对成本低是其他水下混凝土在岛礁施工所达不到的。
