Polymer Modified Steel Fibre Reinforced Concrete Seminar and PPT with pdf report:The steel fiber reinforced concretes are the building materials which are more significance very fast because of the enhancing demand for high building properties in the building materials. These compounds have a more tensile strength to compress, more toughness and more absorption of energy.

All the above properties can be increased by adding a suitable polymer into it and the polymer cement concrete has more strength of tensile, fine behavior of ductile. The network has the void-filling effect and due to that, there is a decrement in the porosity, along with it the pore radius is purified. To enhance the ductile behavior and flexural power of steel fiber reinforced concretes, the styrene butadiene rubber emulsion is combined; to increase the closeness of the cementitious matrix the silica fume and fly ash are availed.

Steel fiber Reinforced Concrete:

General: The plain unreinforced concrete is a fragile material which has a less power of tensile and along with it less capacity of strain. The steel fiber reinforced concrete is majorly used as the important and special reinforcing method for concrete slabs and also for the prefabricated products of concrete. The genuine contribution of the fibers is to enhance the quality of being tough of the concrete under all types of the loads. In the form of small discrete fibers, the fiber reinforcement acts in a way to produce desired results as stiff inclusions in the matrix of concrete.

Mix design of steel fiber reinforcement: Like any other type concrete the mixing proportions of the steel fiber reinforcement depends on the necessary things for a job like strength, workability and much more. The workability of the resulting mix is emphasized by many procedures which are used for the proportioning steel fiber reinforced concrete mixtures. To enhance the workability of high volume mixes of fiber, water decreasing admixtures and superplasticizers are more commonly used in union with the entrainment of the air. 

Properties of SFC: The major properties of the SFC are as follows:

  • Compressive strength
  • Tensile strength
  • Flexural strength

Applications of SFC: From the last 30 years, the SFC has spread a lot that it is complex to make categories among them and also among their applications. The very common applications of the SFC are as follows:

  • Pavements
  • Bridge deck slab repairs
  • Shotcrete
  • Pavements and slabs
  • Airports pavements
  • Tunnel linings

Polymer modified SFC:

The emulsion of a styrene-butadiene rubber is united with the steel fiber reinforced concrete and the polymer modified steel fiber reinforced concrete is as follows:

Experimental polymer: The experimental polymer explains about the following features:

  • Materials: The materials availed in the test were the normal Portland cement, silica fume and fly ash.
  • Specimen preparation and test methods: In the test, the quantity of the polymer and the steel fiber changes but the fly ash and silica fume persist same.

Results:

It gives the results of the following properties:

  • Mechanical properties and cost feasibility
  • Porosity
  • Pore size distribution

Conclusion:

  • The analyzing was done on the microstructure and the mechanical behavior of the materials, they are as follows:
  • The mixing of the steel fibers to a concrete will enhance its compressive power and also about being flexural.
  • The flexural power enhances a lot when it has 3-10 wt% of SBR, there will be a decline in the compressive power when the mixing is at 10 wt% and in overall, and the observed decline is about 16%.
  • The polymer films play the role of bridges and intersect the pores and cracks.
  • The distribution of pore size shows two peaks and they will be present in the range of 5nm-20nm and also in the range of 50nm-1000nm.
  • There will be an enhance in the porosity when the level of SBR is enhanced.
