主 题:rice husk pozzolans cement physical properties SEM X-ray diffraction
摘 要:The properties of lightweight mortar using rice husk can benefit from pozzolanic reaction and from organic fibre reinforcement. The effect of curing and storage on 40x40x 160 mm(3) OPC rice husk mortar specimens is described. Two conditions are studied;one-year storage at 50% RH and at 95% RH. The final specimen properties were characterised by density, strength, SEM, EDS and XRD. It is concluded that at high humidity storage, pozzolanic reaction is well developed but husk fibres deteriorate. The mortar stored at 50% RH has a lower compressive strength and higher flexural strength, indicating inferior pozzolanic reaction and active fibre reinforcement. (C) 2003 Elsevier Science Ltd.
