MIX DESIGN OF SELF COMPACTING CONCRETE USING LIME . Nishant. 1, Himanshu1, A Tiwari1, S Narayan1. 1. National Institute of Technology, Uttarakhand, India . ABSTRACT. In this paper, Investigation for establishing a rational mix-design method with self-compatibility been carried out from the viewpoint of making self-compacting concrete.
Self-compacting concrete (SCC) compacts itself without any vibration. Well proportioned SCC can flow under its own weight through and around congested reinforcement, filling forms completely and producing a void-free mass with little or no mechanical vibration. Buildings made with self compacting concrete . Properties of SCC
May 08, 2014· Compaction is a process of expelling the entrapped air. If we don’t expel this air, it will result into honeycombing and reduced strength. It has been found from the experimental studies that 1% air in the concrete approximately reduces the strength by 6%. Different Methods Of Concrete …
Self Compacting Concrete (SCC) mix design must involve key practices to achieve the requirements of quality and durable mix. The mix designed as per the requirements are tested before using it in construction. The basic properties to be achieved by an SCC mix is flowability, passing ability, strength, and segregation resistance.
Feb 27, 2014· self compacting concrete 1. By the early 1990's, Japan has developed and used SCC. Self compacted concrete is highly engineered concrete with much higher fluidity without segregation and is capable of filling every corner of formwork under its self weight .
Jan 01, 2019· Self-compacting concrete (Self-consolidating concrete) (SCC) Concrete that is able to flow under its own weight and completely fill the formwork, while maintaining homogeneity even in the presence of congested reinforcement, and then consolidate without …
