摘　　要：为了提高废弃橡胶的利用率,提出了将大掺量橡胶混凝土砖用作填充墙砖。对比了橡胶混凝土砖与粉煤灰砖在墙体功能上的优缺点。橡胶粉的掺入提高了砖的抗折强度,而抗压强度却有所降低,但符合隔墙强度要求。随着橡胶掺量的增加,橡胶混凝土砖密度越来越小。橡胶混凝土砖比蒸压粉煤灰砖的吸水率和饱和系数都有所降低,使得橡胶混凝土砖在作为隔墙砖使用时比蒸压粉煤灰砖更加具有优势。In order to improve the utilization of recycled rubber ,a new approach of adopting concrete wall-filling bricks that are made with large proportion of recycled rubber was put forward .The advantages and disadvantages of rubber con-crete bricks and fly ash bricks were compared and analyzed .The adoption of rubber powder enhances the flexural strength while reduces the compressive strength of the bricks ,but not so much as violating the strength requirements for the parti-tion walls .With the increase of rubber content ,the density of the rubber concrete bricks decreases .Compared with the fly ash bricks ,the water absorption rate and saturation coefficients of the rubber concrete bricks are both decreased at a certain amount ,which proves that the rubber bricks are more suited for the partition walls .

关 键 词：橡胶混凝土 抗折强度 抗压强度 吸水率
