Results show that as far as the compressive strength is concerned both aggregates regardless of the water content produced concrete with an acceptable ultimate compressive strength ∫ c ′.However as expected ∫ c ′ decreases as the W/C increased.
Chat OnlineConcrete is one of the most important building materials. From sidewalks to skyscrapers we see concrete everyday everywhere. There are many different kinds of concrete. Reinforced concrete is strengthened by steel. This is done by casting concrete around steel rods or bars and most large structures such as bridges need this extra strong concrete.
