Recycling Bio-BasedWastes into Road-Base Binder: Mechanical, Leaching, and Radiological Implications
(MDPI, 2023-01)
This work presents a physical, mechanical, durability, leaching, and radiological assay of three wastes (egg and scallop shells and olive pomace ash) as road-base binders. Two different waste/Portland-cement ratios (7.5/92.5 ...
