Self Compacting Concrete - Types of Concrete Uses and Applications of Self Compacting Concrete It is used in location unreachable for vibrations e g underground structure deep wells or at bottom of deep sea SCC can save up to 50% in labor costs due to 80% faster pouring and reduced wear and tear on formwork Shotcrete Get price Get Price


Compaction is the process that expels entrapped air from freshly placed concrete and packs the aggregate particles together so as to increase the density of the concrete The compacting and finishing of concrete are generally two separate operations but sometimes particularly with flat horizontal surfaces they become parts of the one operation Get price Get Price

1 1 SELF-COMPACTING CONCRETE Self-compacting concrete (SCC) is defined as the concrete which can be placed and compacted into every corner of formwork purely by means of its self-weight by eliminating the need of either external energy input from vibrators or any type of compacting effort Get price Get Price

Role of Concrete Curing

Curing plays an important role on strength development and durability of concrete Curing takes place immediately after concrete placing and finishing and involves maintenance of desired moisture and temperature conditions both at depth and near the surface for extended periods of time Get price Get Price


Self-consolidating concrete or self-compacting concrete (commonly abbreviated to SCC) is a concrete mix which has a low yield stress high deformability good segregation resistance (prevents separation of particles in the mix) and moderate viscosity (necessary to ensure uniform suspension of solid particles during transportation placement Get price Get Price

May 08 2014What is Compaction? 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 Compaction There are two methods [] Get price Get Price
