Influence of Steatite and Fly Ash on the Fresh-Hardened Properties and Micromorphology of Self-Compacting Concrete

Table 1

Trial and error method to obtain SCC.

Trial	Mix ratio	Identified fault	Implemented action to eradicate the fault according to European guidelines (as per Table C.2)
1	1 : 1.52 : 1.52 with - ratio of 0.48	Rapid loss of workability	Use different superplasticizer, use slower reacting cement type
2	1 : 1.52 : 1.52 with ratio of 0.48	Segregation	Increase the mortar volume, reduce the water content
3	1 : 1.52 : 1.48 with ratio of 0.4	Viscosity too high	Increase the water content
4	1 : 1.52 : 1.48 with ratio of 0.43	Nil	—
