ABSTRACT We all know that mortar is nothing but the mixture of cement, sand and water. When concrete is used in presence of reinforcement then it is called as RCC (Reinforcement cement concrete). And if we eliminate fine aggregates concrete then it is called as no fines concrete. It is also known as porous, pervious, gap graded, permeable, and cellular concrete. No fines concrete is widely used construction of pavements, for roadways where less traffic is observed and for sidewalks. The typical grading of coarse aggregates used for no fine concrete is either single-sized or ranging between 9.5 mm to 19 mm to gain sufficient strength of concrete without reducing porosity. In this study no aggregate concrete (NAC) an attempt has been made considering steel fibers of different aspect ratios as NAC is having brittle failure and less tensile strength. The compressive strength, flexural strength, and split tensile strength of control concrete mix, NAC mix without steel fibres and NAC mixes with steel fibres are studied. The paper gives idea about strength and durability properties of no aggregate concrete using fibers. Keyword: No aggregate concrete (NAC); Fly ash; Steel fibers; drying shrinkage; Water absorption. INTRODUCTION No aggregate concrete (NAC) is an advanced type of concrete in which the use of coarse aggregates are totally eliminated. This leads to preservation of natural resources of rocks such as hills and mountain. Also this project eliminates the use of sand to stop erosion of river beds. NAC is the concrete which have low density and gives high order of strength. It proves economical as it does not contain coarse as well as fine aggregate. Compaction is not required for this particular type of concrete for casting in situ situation. It is also easy to pump this concrete at high levels without taking additional efforts. It is also possible to reduce wall thickness with this concrete which leads to more floor area available for the use. Special care has to be taken while mixing and placing of No fine concrete. OBJECTIVE OF THE STUDY NAC is the new type of concrete. It is having low density and high order of strength but it is brittle in failure and has low tensile strength. So to overcome with this aspect in this study steel fibres were introduced in NAC. These NAC mixes with steel fibres were compared with Control concrete and NAC mixes without steel fibres.  To study the strength parameter of control concrete mix, NAC mix without steel fibres and NAC mixes with steel fibres.  To study the effect of water absorption on control concrete mix, NAC mix without steel fibres and NAC mixes with steel fibres.  To study the flexure test on RCC beams of control concrete mix, NAC mix without steel fibres and NAC mixes with steel fibres.
