NO AGGREGATE CONCRETE

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.
