摘　　要：硫磺聚合物混凝土/砂浆是一种采用改性硫磺作为粘结剂的高性能复合材料,其主要特点是强度高、吸水性低、固化迅速和耐酸碱性良好。本试验的目的是研究废轮胎橡胶在改性硫磺砂浆中作为增韧剂和防开裂稳定剂的可能性。研究了橡胶改性硫磺砂浆的机械性能并将其与波特兰水泥砂浆进行了比较。Sulphur polymer concrete/mortar is a high-performance composite material in which modified sulphur is used as the binder, with main features of high strength, low water absorption, quick setting and high resistance to acidic and basic environments. The objective of this work is to investigate grounded tyre rubber particles as possible t ber modified oughness enhancer and crack stabilizer in modified sulphur mortars. Mechanical properties of the rubsulphur mortars have been investigated and compared with those of Portland cement mortars.
