Pervious concrete is a construction material widely used in pervious pavements. Pozzolanic materials replacing partially Portland cement can improve mechanical and hydraulic issues associated with the use of pervious concrete. This paper reports the use of wastes from the sugar cane industry (sugar cane bagasse ash and sugar cane straw ash) and their influence on the mechanical and hydraulic properties of pervious concrete for different binder:aggregate mass ratio (1:3.5, 1:4.0, 1:4.5, 1:5.0). The assessed pervious concrete achieved a compressive strength in the range 7.4–14.2 MPa, a total porosity between 26.4 and 32.4% and an infiltration rate of 0.6–1.3 cm/s.

透水混凝土是一种广泛用于透水路面的建筑材料。部分替代波特兰水泥的火山灰材料可以改善与使用透水混凝土相关的机械和水力问题。本文报道了甘蔗工业废弃物（甘蔗渣灰和甘蔗秸秆灰）的使用情况及其对不同粘结剂：骨料质量比（1:3.5, 1:4.0）的透水混凝土力学和水力性能的影响。 , 1:4.5, 1:5.0)。评估的透水混凝土的抗压强度在 7.4-14.2 MPa 范围内，总孔隙率在 26.4 和 32.4% 之间，渗透率为 0.6-1.3 cm/s。
