摘 要:将稻壳灰等量部分替代水泥加入到混凝土中制备稻壳灰混凝土,并对稻壳灰混凝土进行7d和28d龄期的力学性能、抗冻性能、抗氯离子渗透性能和抗酸侵蚀性能的测试。结果表明,稻壳灰的加入能够显著地改善混凝土的内部结构,使其更加密实,从而增强了稻壳灰混凝土的力学性能、抗冻性能、抗氯离子渗透性能和抗酸侵蚀性能。当稻壳灰的掺量为20%时,混凝土的性能最佳,此时稻壳灰对混凝土的增强效果最好。
Abstract: The rice husk ash for same amout is added into concrete for preparing rice husk ash concrete. The mechanical properties at 7d and 28d, frost resistance, chloride penetration resistance and acid resistance properties of rice husk ash concrete are investigated. The results show that adding rice husk ash can improve the structure of concrete, which can finally enhance the mechanical properties, frost resistance, chloride penetration resistance and acid resistance properties. The maxmum properties of rice husk ash concrete is obtained with the 20% dosage of rice husk ash, at this time, the strengthending effects of rice husk ash on concrete is best.
