【摘要】：国内已有大量对利用粉煤灰替代水泥制备泡沫混凝土的研究,但利用油页岩渣替代水泥的研究几乎没有。为此,对油页岩渣泡沫混凝土性能进行系统试验研究,并将其干密度、抗压性能、抗折性能与粉煤灰泡沫混凝土进行对比分析。结果表明,利用油页岩渣和粉煤灰替代部分水泥制备的泡沫混凝土的干密度都比同等条件下制备的水泥基泡沫混凝土的干密度低;油页岩渣泡沫混凝土和粉煤灰泡沫混凝土的干密度、抗压强度、抗折强度随着油页岩渣和粉煤灰掺量增大而先降低后升高,即存在拐点;在油页岩渣和粉煤灰掺量相同时,油页岩渣泡沫混凝土的干密度、抗压强度、抗折强度都较粉煤灰泡沫混凝土有不同程度的降低。
[Abstract]:There has been a lot of research on the use of fly ash instead of cement to prepare foamed concrete, but there is hardly any research on replacing cement with oil shale slag. Therefore, the performance of oil shale slag foam concrete has been studied systematically and its dry density has been studied. The compressive and flexural properties of fly ash foam concrete are compared with that of fly ash foam concrete. The dry density of foam concrete prepared by replacing some cement with oil shale slag and fly ash is lower than that of cement based foam concrete prepared under the same conditions, and the dry density of oil shale slag foam concrete and fly ash foam concrete is lower than that of cement based foam concrete prepared under the same conditions. The compressive strength and flexural strength decrease first and then increase with the increase of the content of oil shale slag and fly ash, that is, there is an inflection point, when the content of oil shale slag and fly ash is the same, the dry density and compressive strength of oil shale slag foam concrete, The flexural strength is lower than that of fly ash foam concrete.
