---------------------------------------------------------------------***--------------------------------------------------------------------SFRC is the developed by addition of steel Fiber with Abstract – Concrete is being widely used in the construction work e.g. buildings, bridges, highways, tunnels etc. due to its high strength. A lot of research has been done or ongoing to improve the concrete strength with the advancement of technology. Relating to this a study has been carried out on the impact of concrete strength by using acrylic latex polymer modified concrete and steel fibre reinforced concrete (SFRC). It was observe in previous researches, in addition of SFRC increases the mechanical properties (compressive strength, tensile strength and flexural strength) of concrete. Now we will observe that the Involvement of acrylic latex polymer individual or combined with steel fibres effects on mechanical properties of concrete. For this, we have prepared a design mix of M25 grade as per IS 10262:2009.
Keywords – Concrete, construction, polymer, steel fiber,

1. INTRODUCTION Many new construction materials are being developed all over the world to improve the concrete properties with considerable effect. The economic progress of any construction project depends more on intelligent use of the materials and constant improvement of available materials. So that we can achieve the high performance of concrete for various construction work by applying the steel fibre's and polymers in concrete. Concrete is the mixture of cement ,coarse aggregates, fine aggregates, and water. It is widely used in construction industry. Cement is used as a binding material in concrete. After addition of water in concrete, chemical reaction takes palace and concrete sets rapidly. Concrete plays a vital role in the development of any nation or any human civilization from ancient times. Concrete is usually characterized by its compressive strength. Concrete is widely used for making architectural structures foundations, brick/block walls, bridges/overpasses, motorways/roads, runways, structures, dams, pools/reservoirs, pipes, fences and poles and even boats. © 2017, IRJET

concrete at the time of mixing with definite proportions. There are many types of fibres such as steel fibre, glass fibre, rice husk etc. which are used in concrete. Steel fibres are mostly used now a day. These steel fibers are helpful to reduce the crack width in concrete member which results in reducing the permeability of concrete. Due to this concrete gains durability and strength for a very long time in compare to the concrete without steel fiber. Steel fiber also improves the toughness and load carrying capability in the concrete members. Now a days many polymers are using in concrete to improve the various properties of concrete. Peoples are taking advantages polymers in form of Oils, tars, and gums etc. Polymer modified concrete are prepared by mixing of Portland cement concrete with a advanced polymers such as polyvinyl acetate, Styrene butadiene rubber, acrylic latex polymer and ethylene vinyl acetate. Out of these polymers acrylic polymer has a constant color which makes its very suitable construction materials in architecture. There are various research work are done and going on due to the massive impact of polymer on concrete. Fiber reinforced polymer concrete (FRPC) consist of mixture of fibers and polymer in concrete. This type of concrete also gives the remarkable observation in concrete properties. 2. EXPERIMENTAL INVESTIGATION We take a series of specimen of a specific size and shape for experiment. Cubes of size (150 mm × 150 mm), prisms of size (100 mm × 100 mm × 500 mm) and cylinders of size 150 mm dia. × 300 mm in height are taken for observing the compressive strength , flexural strength and tensile strength of concrete respectively. There are four types of concrete mixes of M25 concrete grade is prepared with or without using acrylic latex polymer and steel fibres. These are plain cement concrete( M25) , Plain cement concrete with acrylic latex polymer ( M25+ AL), plain cement concrete with steel fibre (M25+SF), and plain cement concrete with combination of acrylic latex polymer and steel Fibre
