self compacting concrete containing shell lime

Effect of Local Materials on Self Compacting Concrete - IJERT

The material passing through 90 µm sieve is used in the self compacting mortar (SCM ) mixes. The properties of RHA is used in this paper is shown in Table 6. From that table, whatever RHA obtained from the burning process is with moderate fineness and high loss of ignition. These characteristics would certainly affect the SCM mixes.

Development of self compacting concrete with various mineral admixtures

The advantages of using shell lime powder are that it blends in the concrete mix easily and forms a very good cohesive mix. It also acts as a good viscosity modifier for fresh concrete paste. The research shows that utilization of shell lime powder less than 30% in concrete gives satisfactory results [9].

compacting gravel /crushed rock fill - Fine Homebuilding

Probably self compacting #57, which is 1/2 to 3/4-inch gravel is generally considered to be self compacting. This is because there are no fines to inerfer with the movement, so it goes to where there is direct contact between the particles. Short of braking the rocks, which would require a great deal of force, the material won't get any tighter.
