An investigating the effect of using Lumachelle as a substitute of aggrigate in RCC

According to lack of sufficient fine aggregate in some coastal area, using of other aggregate material are advisable. In this experimental study use of Lumachelle as a substitute of fine aggregates and replacement of lime and pozzolan as a part of cement are investigated on roller compacted concrete...
