Influence of waste concrete aggregates on the performance and durability of OPC concrete / Ahmad Ruslan Mohd Ridzuan, Azmi Ibrahim and Abdul Manaff Mohd Ismail

The effects of using crushed waste concrete as course aggregates upon compressive strength and carbonation were investigated. Waste concrete cubes, which had been tested for compressive strength in compliance with construction specification, were crushed and utilized as coarse recycled aggregates i...
