Thesis on self compacting concrete

Construction One solution for the achievement of durable concrete structures is the employment of SCC which can be compacted into every corner of a formwork, purely by means of its own weight and the without the need for vibrating compaction.

SCC was first developed in to achieve durable concrete structure. Investigations for establishing a rational mix-design method and Self-compact ability testing methods have been carried out from the view point of making SCC a standard concrete.

Modern application of SCC is focused on high performance, better and more reliable and uniform quality. It has proved to be beneficial because it allows faster construction, improved durability and greater freedom in Thesis on self compacting concrete etc.

It is being blindly believed that SCC is much costlier than normal or high strength concrete. Though the material cost for SCC is high, if other components of costs such as cost of compaction, finishing etc are considered, one can realize that SCC is certainly is not a costly concrete for comparable strength.

Portland cement concrete mixes are being used over years. They are mixed, placed into the form and then compacted.

It is essential to compact the concrete so that it completely covers the reinforcement bars and fill the space within the forms, for meeting strength and durability requirement. If the compaction is not complete, it will lead to loss in strength and also effect the performance of the structure.

Design and testing of self-compacting concrete Download 15MB Abstract Self-compacting concrete SCC can flow into place and compact under its own weight into a uniform void free mass even in areas of congested reinforcement.

The compaction becomes difficult when percentage of reinforcement is high and rebars get congested without allowing for insertion of the vibrator at some places.

In such places the concrete should be flowable in nature and should be self compacted. SCC has more favorable characteristics such as high fluidity, good segregation resistance and the self compacting ability without any need of vibration during the placing process.

Development of SCC For several years beginning inthe problem of the durability of concrete structures was a major topic of interest in Japan. The creation of durable concrete structures requires adequate compaction by skilled workers.

By the yearthe SCC has become popular in Japan for prefabricated products and ready mixed concrete. Duringthey founded European federation of natural trade associations representing producers and applicators of specialist building products EFNARC.

All types of cement can be used. But for better SCC mix high grade cement is used. The maximum size of aggregate is generally limited to 20mm. For congested reinforcement mm size aggregate is desirable. Well graded cubical or rounded aggregates are desirable. Grading must be uniform throughout the work.

High quality must be established on the same line as that for using reinforced concrete or prestressed concrete.
