Concrete Mix Design - Art of Balancing the Conflicting Requirements Why we need to explore potentials of Indigenous materials in Pakistan Concrete, like all other engineering materials, needs to be designed for properties like strength, durability, workability and cohesion. This extremely versatile material can be designed for strength ranging from 10 Mpa to 200 Mpa and workability ranging from 0 mm slump to 250 mm slump. It’s all characteristics including strength, workability and durability, are in our hands. One can make it flow like a liquid, make it light like foam and dense like a stone. One can predict [...]
