Assessment of Behaviour of M-Sand Concrete by Addition of Different Types of Steel Fibers: An Update

This chapter assesses the behaviour of M-Sand Concrete by Addition of Different Types of Steel Fibers. Concrete being a global material in the construction industry is being a research material as an alternative and effective one is being aimed upon and the limit of experimentation is infinite. The material such as M-Sand and Steel Fiber leads to major variation in strength parameters of concrete. The objective is to achieve required charactertics such as strength, durability and workability in an economical manner. The use of manufactured sand as an alternative to natural sand in the production of concrete results in cost savings and an improvement in strength metrics. Concrete gains strength as a result of the use of various steel fibre kinds, including crimped steel fibres. In this research paper M-Sand is replaced by Natural Sand completely along with different proportion of crimpled steel fibers i.e. 0.00%, 0.50%, 1.00%, 1.50%, & 2.00% as different mix with nominal coarse aggregate and OPC 43 grade of cement. The research works shows that crimped steel fiber at 1.50% the compressive strength of concrete increases because of the increase in crimped steel fiber due to which interconnection between void are reduced.The concrete prepared will be of M25 grade concrete by adopting IS code method. With varying percentage of steel fibre in addition to M-Sand the proportion have varying strength. It has been concluded that the concrete prepared by using M-Sand as replacement of fine aggregate gives uniform workability throughout the mix.
