| 摘 要： | 依据"快冻法",研究了粉煤灰掺量、稻壳掺量和水灰比对稻壳混凝土抗冻性的影响.结果表明:稻壳掺量为10%和8.6%、粉煤灰掺量为17%～20%时稻壳混凝士具有良好抗冻性;随水灰比的增大,抗冻性能变差;水灰比在0.4～0.43范围内时其抗冻性能最好,此外影响稻壳混凝土抗冻性的影响因素顺序为稻壳掺量>粉煤灰掺量>水灰比.

| Abstract: | According to"Quick Freezing Method",the influence of different fly ash,rice husk and water-cement ratio to the frost resistance of rice husk concrete is studied.The results show that when the amount of rice husk is 10% and 8.6% and the amount of fly ash is 17%～20%,the rice husk concrete has good anti-freezing properties,the frost resistance of the concrete is decreased with water-cement ratio increasing,and the frost resistance of the concrete is best when the water-cement ratio is in the range of 0.4 to 0.43.In addition,it could be concluded that the factors affecting the strength of the concrete are rice husk>fly ash>water-cement ratio. |
