长期养护下稻壳混凝土抗压强度试验研究
|
摘要
选用农业废弃的稻壳为骨料,同时用粉煤灰代替部分水泥制备混凝土,研究长期养护条件下其抗压强度的规律。试验结果表明,稻壳掺入会影响混凝土内部结构,影响破坏形式,其抗压强度随水灰比的增大逐渐降低。粉煤灰在混凝土中的掺量达到38%时,为抗压强度峰值,掺量超过38%,抗压强度随水灰比的增大显著地下降。
Agricultural waste rice husk as the aggregate and fly ash instead of partial cement were seleted to make the concrete and the law of the compressive strength under long-term conservation conditions was studied. The test results show that the content of rice husk affects the internal structure of the concrete test block, destroy types of the test block, and the compressive strength gradually decreases with the increase of the water-cement ratio. When the content of fly ash reaches 38% in concrete, it is the peak value of compressive strength, and the content of fly ash exceeds 38%. The compressive strength also decreases obviously with the increase of water-cement ratio.
