Pour a 1-inch layer of crusher run stone into the trench. Spread the stone out as evenly as possible using a rake. Push a plate compactor over the crusher run stone to tamp it down. Place the level on the layer of stone to ensure that it is even. Does crushed stone need to be compacted? I read several places that 3/4" crushed stone is "self ...

Self Compacting Fiber Reinforced Concrete (SCFRC) is the one where fibres are added to the self compacting concrete, which is able to flow under its own weight, and completely fill the formwork and encapsulate the reinforcement, while maintaining homogeneity and can consolidate without the need for vibration compaction.
o Self compacting concrete is an innovative concrete that does not require vibration for placing and compaction. o Self compacting concrete is a concrete that can be compacted into every corner of a formwork purely by means of it's own …
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.
o Self compacting concrete is an innovative concrete that does not require vibration for placing and compaction. o Self compacting concrete is a concrete that can be compacted into every corner of a formwork purely by means of it's own weight, with out using any external vibrators. o It is a highly engineered concrete with much higher fluidity.
