Title: Structural Performance Of Semi-Rigid Connection Steel Frames Authors: Mohit, Satani; Joshi, Darshan Abstract: Civil structure should be economical, durable & stable. Economical structure is a main goal of structure engineer in recent years. Out of many methods to generate economical structure one method is semi rigidity of connection. By the concept of semi rigidity, cost optimization can be achieved by transferring desire moment from beam to column or vice -versa. In this concept cost of connections, beam & column is variable factor & function of semi rigidity. By trial & error method element optimization can be achieve. The variation of moment, shear force, axial force, displacement and stress is investigated in a selected axis of the structures. This study reveals that the effect of semi-rigid connections on structural systems shows different variations from structure to structure. Connection stiffness depends on semi rigidity, material and shape of section.

Title: Experimental Study on Self-Compacting Concrete using E-plastic waste materials in partial replacement of coarse aggregate Authors: Nandawana, Nayan N.; Bhuva, Prashant K.; Borad, Chetan V. Abstract: Use of waste materials and by-products is a partial solution to ecological and environmental problems. Utilization of these materials not only helps in getting them used in cement, concrete and other construction materials, it reducing the cost of concrete and cement manufacturing, but also has many indirect benefits such as reduction in land-fill cost, saving in energy, and protecting the environment from possible pollution effects. E-waste (EW) is abbreviation of Electronic waste, consists of discarded computers, TV, Laptop, refrigerators – basically all electrical or electronic appliance that has reached its end-of-life. Efforts have been made in the concrete area to use non-biodegradable components of E-waste (EW) as a partial replacement of the coarse aggregates.An experimental study is made by preparing specimens by utilizing E-plastic waste particles as coarse aggregates in Self-Compacting Concrete (SCC) with a percentage replacement from 0% to 30% i.e. (5%, 10%, 15%....up to 30%). And Conventional specimens are also prepared for M30 and M35 grade Self-Compacting Concrete (SCC) without using E-plastic waste aggregates. By conducting tests for both the specimens Fresh Properties and hardened properties of Self-Compacting Concrete (SCC) are studied. It is found that use of E- plastic waste aggregates results in the formation of Self-Compacting Concrete (SCC) which has lesser weight than that of conventional concrete. This study ensures that reusing of E-waste as coarse aggregate substitutes in concrete gives a good approach to reduce cost of materials and solve solid waste problems posed by E-plastic waste.

Title: Modification in Self-Compacting Concrete Authors: Agnihotri, Namrata D.; Chovatiya, Mitul K. Abstract: Self-compacting concrete (SCC) is a concrete that does not require vibration for placing and compaction. In plastic state it is able to flow under its own weight, completely filling formwork and achieving full compaction, without any segregation and maintaining its homogeneity even in the presence of congested reinforcement and can flow through all shapes and obstructions. The hardened concrete is dense, homogeneous and has almost the same engineering properties and durability as normal concrete. By adding Polypropylene fibre, Polyester fibre. Glass fibre .Fibres arrests shrinkage cracks and increases resistance to water penetration, abrasion and impact. It makes concrete homogeneous and also increases compressive behaviour, ductility and flexural strength together with improving a structure‟s ability to absorb more energy the super plasticizer and viscosity modifying agent are added in Self compacted concrete. Test on fresh concrete is slump spread for all trial mixes. The mix that has the largest slump spread is tested with V-funnel, L-shaped box and U-shaped box Conventional specimens are also prepared for M20.By conducting tests for the specimens the properties of concrete will be investigate. This study ensures that using of fibre as substitutes in concrete gives a good approach to reduce cost of materials and will accomplish the better properties of self-compacted concrete at all ages.

Title: Performance of Roof Tile Powder as Partial Replacement of Cement in Self Compacted Concrete Authors: Chovatia, Mitul K.; Akbari, Yogesh V.; Vaniya, Shradhha R. Abstract: The delegated concrete works could promote structure failure after earthquake. Compaction and pouring of concrete on element of structure with dense reinforcement and structural joint like beam column joint are difficult. So the self-compacted concrete is a better solution for this problem. Use of self-compacted concrete that has flow ability, filling ability and passing ability is better than the normal concrete. On this research using of roof tile powder in self-compacted concrete give better workability and also strength of self-compacted concrete. The roof tile powder is easily available in Indian villages. The possibility of using roof tile powder (RTP) with fly ash for partial replacement of ordinary Portland cement (OPC) will explore in this research. An experimental study is made by preparing specimens by utilizing roof tile powder (RTP) as partial replacement of ordinary Portland cement in Self compacted concrete with a percentage replacement from 0% to 50% i.e. (0%, 10%, 25%, 30%, 40% and 50%) . The super plasticizer is added in Self compacted concrete. Test on fresh concrete is slump spread for all trial mixes. The mix that has the largest slump spread is tested with V-funnel and L-shaped box. Conventional specimens are also prepared for M30 and M35 grade Concrete without using RTP and fly ash. By conducting tests for both the specimens the properties of concrete will be investigate. This study ensures that using of roof tile powder (RTP) as partial replacement of ordinary Portland cement substitutes in concrete gives a good approach to reduce cost of materials and will accomplish the better properties of self-compacted concrete at all ages.
