Abstract. No-fine concrete (also called as pervious concrete or porous concrete) is a lightweight concrete made up of primary binder and coarse aggregates with little or no sand. Due to the reduced amount or absence of fines, it produces large number of voids which improves permeability to greater extent. Hence this type of concrete can be used in pavements and in parking lots. The literature review is carried out to study the physical and mechanical properties of no-fine concrete with additives. Various reports were collected and studied about variation in physical and mechanical properties of pervious concrete with different additives. Additives may be either mineral additives (fly ash, silica fumes, rice husk ash etc..,) or chemical additives (plasticizers, super plasticizers, retarders etc..,). Our project involved the utilization of recycled coarse aggregates, fly ash and rice husk in no-fine concrete. After this study, it was concluded that ‘upon the addition of additives, it increases permeability by decreasing its strength and vice-versa’. Balancing its permeability and strength remains challenging.
