摘　　要：在橡胶混凝土中掺入粉煤灰和矿渣,不但可减轻包头地区的环境负担,节约资源和能源,还利于其推广应用。试验结果表明:单掺粉煤灰或矿渣时,橡胶砂浆的压折比降低,但抗冲击性能变化不明显,只有在单掺粉煤灰10%和20%时,橡胶砂浆的干缩率是降低的。双掺粉煤灰10%、矿渣20%时,橡胶砂浆的各项性能与未使用矿物掺合料时相当,这说明矿物掺合料的使用对于橡胶砂浆或混凝土的性能几乎无改善作用,只可降低其使用成本。Using fly ash and slag in rubber concrete can reduce Baotou area environment burden and save resources and energy and be favorable for rubber concrete popularization and application.Test results showed that using single fly ash or slag ,rubber mortar compressive flexural strength ratio reduced and impact resistance performance did not change significantly.Only using fly ash 10% or 20%, rubber mortar dry shrinkage reduces.Using fly ash 10% and slag 20% ,rubber mortar performance was equal to unused;this shows that mineral admixture had little improvement on rubber mortar performance; only is good for reducing rubber mortar cost.
