Making concrete is simple in theory—you simply combine cement with water and an aggregate like sand or crushed stone—but the strength and durability of the mixture can vary quite a bit depending on the water ratio and consistency of the mixture....
Determination of Indirect Tensile Strength of Bituminous Concrete Mix Prepared Using Stone Dust and Cement as Filler MaterialsPavement engineers are too much concerned about the tensile properties of bituminous mix because of the problems associated with cracking. Hence tensile strength of bituminous ...
