Seawater mixed culture coral reef sand C120UHPC and preparation method thereof
The invention discloses seawater mixed culture coral reef sand C120UHPC and a preparation method thereof. The UHPC comprises the following components in proportion: 690.2 kg/m<3> of aluminoferrite cement; 138.6 kg/m<3> of fine coral reef powder; 194.1 kg/m<3> of coarse coral reef powder; 776.3 kg/m<3> of quartz sand; 138.6 kg/m<3> of silica fume; 34.7 kg/m<3> of fly ash; 182.3 kg/m<3> of seawater;41.6 kg/m<3> of a superplasticizer; and 140.4 kg/m<3> of steel fibers. The invention also discloses a preparation method of the UHPC, and a curing method comprises the following steps: placing a concrete test block in a standard curing chamber, covering the test block with wet linen, or placing the test block in water, maintaining multiple watering curing in the curing process, and preventing evaporation of water in the concrete, so that the curing method avoids steam curing of the UHPC. The seawater mixed culture coral reef sand C120UHPC and the method have the technical advantages that themethod is beneficial to application and popularization of UHPC, has important significance in meeting large-scale engineering construction of island reefs in the South China Sea, achieving local material utilization, reducing cost, shortening the construction period and the like, the construction cost of offshore engineering is reduced, and the requirements for greenization, energy conservation and environmental protection of civil engineering are met.
本发明公开了一种海水拌养珊瑚礁砂C120UHPC及其制备方法，其UHPC组成及配比包括：铁铝酸盐水泥690.2kg/m；细珊瑚礁粉138.6kg/m；粗珊瑚礁粉194.1kg/m；石英砂776.3kg/m；硅灰138.6kg/m；粉煤灰34.7kg/m；海水182.3kg/m；高效减水剂41.6kg/m；钢纤维140.4kg/m；本发明还公开了该UHPC的制备方法，养护方式为：将混凝土试块放置在标准养护室中，用湿麻布将试件覆盖，或者将其放置在水中，养护过程中保持多次洒水养护，防止混凝土中水分的蒸发，这种养护方法避免了UHPC蒸汽养护。本发明具有以下技术优势：本发明有利于UHPC应用与推广，而且对满足我国南海岛礁大规模工程建设、实现就地取材、降低成本、缩短工期等都具有重要意义，并且本发明降低了远海工程施工成本，也符合土木工程绿色化、节能化、环保化的需求。
