This research has a purpose to study the physical properties of concrete when using bagasse as an alternative for coarse aggregate in the mixture of concrete quality fc’ 17 MPa. The research consisted of 3 tests, they were porosity, shrinkage, compressive strength. The bagasse used were 0,3%, 0,5% and 0,7% of total weight of coarse aggregate. The compresive strength and porosity was tested at…
