The various methods of hand compaction are as given below. 1. Rodding. It is a method of poking with 2m long, 16 mm dia rod at sharp corners and edges. The thickness of layers for rodding should be 15 to 20 cm. 2. Ramming. It is generally used for compaction on ground in plain concrete. It is not used either in RCC or on upper floors.

Best Practices Guidelines for Self-Consolidating Concrete 3 WHAT IS SELF-CONSOLIDATING CONCRETE? Self-Consolidating Concrete (SCC), also referred to as self-compacting concrete, is able to flow and consolidate on its own. At the same time it is cohesive enough to fill spaces of almost any size and shape without segregation or bleeding.

Self-Compacting Concrete Uses . Self-compacting concrete has been used in bridges and even on pre-cast sections. One of the most remarkable projects built using self-compacting concrete is the Akashi-Kaikyo Suspension Bridge.In this project, the SCC was mixed on-site and pumped through a piping system to the specified point, located 200 meters away.

Self Compacting Concrete. Self Compacting concrete is a type of concrete that is more flowable than the normal concrete and compacted by itself. Not like normal concrete, vibration is not required to compact it. It flows through the connection areas with reinforcements. Most of us know what is the self compact concrete means.

Because of CO2 emission in the atmosphere temperature is increased in atmosphere and Global warming ...

concrete is dense, homogeneous and has at least engineering properties at par with and durability as traditional vibrated concrete. The principle behind Self Compacting Concrete (SCC) is that the settlement of aggregates is related to the viscosity of the fresh concrete. SCC can be produced using the same ingredients as that of normal concrete.

Self-compacting concrete (S.C.C) which is produced through the addition small amount of Nano silica results in concrete with high strength and Durability. Hence, it could be used to construct complex shapes and improved concretes mechanical strength. Self-cleaning concrete could be made by adding nano titanium dioxide (Nano TiO2).

Self curing concrete Self curing concrete.pptx (Size: 855.52 KB / Downloads: 253) What is curing of concrete? Curing is the maintenance of a satisfactory moisture content and temperature in concrete for a period of time immediately following placing and finishing so that the desired properties may develop.
