High-strength obdurability improved rubber concrete as well as preparation method and application thereof
The invention provides high-strength and high-toughness improved rubber concrete as well as a preparation method and application thereof. The high-strength and high-toughness improved rubber concrete is prepared from a gelling component, a water reducing component, a filling and compacting component, an energy absorbing component, an improving component, a shrinkage reducing component and a defoaming component, the gelling component is PO42.5 ordinary Portland cement; the water reducing component is a polycarboxylic acid water reducing agent; the filling and compacting components comprise coarse aggregate and fine aggregate; the energy absorption component is 40-mesh rubber treated by a NaOH solution; the improvement component is PE fiber and metakaolin; the shrinkage reducing component is a shrinkage reducing agent; the defoaming component is a THIX-5682 type polyether defoaming agent; the mass ratio of the components is (205): (329.4)-(347.7): (1618): 50: (1.94)-(5.82): (18.3)-(36.6): (3.9): (19.5). The concrete disclosed by the invention is high in strength, good in toughness, excellent in anti-shock effect and suitable for tunnel ductile layer materials in high-intensity areas.
本发明提供一种高强度强韧性改良橡胶混凝土及其制备方法和应用，包括胶凝组分、减水组分、填充密实组分、吸能组分、改良组分、减缩组分和消泡组分；胶凝组分为PO42.5普通硅酸盐水泥；减水组分为聚羧酸减水剂；填充密实组分为粗骨料和细集料；吸能组分为经NaOH溶液处理的40目橡胶；改良组分为PE纤维和偏高岭土；减缩组分为减缩剂；消泡组分为THIX‑5682型聚醚消泡剂；各个组分的质量比为205：329.4～347.7：1618：50：1.94～5.82：18.3～36.6：3.9：19.5。本申请的混凝土强度高、韧性好、抗减震效果优良，适用于高烈度地区隧道韧性层材料。
