Coral aggregate modification and enhancement method
The invention discloses a coral aggregate modification and enhancement method, which belongs to the technical field of aggregate cleaning equipment, and comprises the following steps: crushing coral aggregate, and screening the crushed coral aggregate through a screening mechanism to obtain coral aggregate with the particle size of 5-20mm; the screened coral aggregate is sequentially subjected to water washing, acid pickling and water washing and then dried; then cement is prepared into cement paste according to the water-cement ratio of 1: 2, the prepared cement paste and the dried coral aggregate are added into a stirring machine to be stirred, the pressure of 2 atm is applied in the whole stirring process, the lasting time is 30 min, stirring is conducted for 1 min every 5 min, and the stirring frequency is 30 r/min; after stirring is completed, the coral aggregate is leached out and cured, and the curing condition is that the curing temperature is 20 +/-2 DEG C within 28 days, and the humidity is not smaller than 95%. The porosity and the water absorption rate of the coral aggregate are greatly reduced, and the strength of the coral aggregate is improved, so that the coral concrete with higher strength grade is prepared, various excellent properties are obtained, the cost of the used materials is low, and the required time is short.
本发明公开了一种珊瑚骨料改性增强方法，属于骨料清洗设备技术领域，包括：将珊瑚骨料破碎后经过筛分机构筛分出粒径为5‑20mm的珊瑚骨料；将筛分后的珊瑚骨料依次进行水洗、酸洗、水洗后烘干；再将水泥以水灰比为1：2进行调制成水泥浆，将调制好的水泥浆与烘干后的珊瑚骨料加入搅拌机中进行搅拌，搅拌过程全程施加2atm的压力，持续时间为30min，其中，每隔5min搅拌1min，搅拌频率为30r/min；搅拌完成后将珊瑚骨料沥出进行养护，养护条件为：28d内养护温度在20℃±2℃，湿度不小于95％。本发明极大程度的降低珊瑚骨料的孔隙率和吸水率，提高珊瑚骨料的强度，从而配置更高强度等级的珊瑚混凝土并获得优异的各项性能，且所用材料成本低廉，所需时间较短。
