Abstract: - Self-Compacting Concrete (SCC) - an advanced concrete which can flow under its own weight without the 1.2 LITERATURE SERVEY. need for vibration. SCC is characterized by favorable filling, passing and segregation resistance properties, Chiranjeevi Tadi and T. Chandrashekar Rao et.al making it practical for use in concrete structures with (2022) Experimental Study on behavior of SCC congested reinforcement and complex formwork. The Pavement with cement partial replaced with GGBS present study is carried out on M30 grade Self-Compacting concentrated essentially towards fresh mechanical, and Concrete with inclusion of Polycarboxylate Ether (PCE) durability properties needed for use in pavement superplasticizer and Ground Granulated Blast Furnace applications. In this context, SCC mixes were produced Slag (GGBS) as partial replacement of cement. SCC for PCE superplasticizer at different concentrations (0% to by partially replacing the GGBS from 0% to a maximum 3%) and establishes some fresh and hardened properties. percentage in order to develop optimum partial The evaluation of fresh concrete properties was done by replacement of GGBS. They wrote in their research, Slump Flow Test, T₅₀ Time Test, V-Funnel Test and L-Box "The better the workability properties of slump flow, Test for flowability, viscosity and passing ability. Various passing ability and segregation resistance can be fresh and hardened properties of concrete such as attributed to the finer particle size of GGBS compared compressive strength test on concrete cubes (casting, to Portland cement and hence, it provides better packing curing and crushing in the compression testing machine) effect. The mechanical properties like compressive were performed after 7, 14 and28 days. strength, split tensile strength and flexural strength were The behaviors of SCC having 1.5% and 2% super plasticizer were tested, and the test results revealed that noticed highest when cement is replaced 40% by GGBS both mixes (SCC-1.5 PCE and SCC-2PCE) exhibited an but then started decreasing gradually with higher levels. excellent workability, flow ability, pass ability, and The samples also exhibited reduced drying shrinkage reduced segregation according to EFNARC specifications. and improved abrasion resistance, parameters of interest Compressive strength of concrete improved using PCE in evaluation of rigid pavement performance. and GGBS, GGBS contributed by decreasing the cement Polycarboxylate Ether (PCE) superplastizer was used to utilization and modifying durability attributes, which obtain same consistency without segregations of high eventually helped towards sustainability.
