Concrete mix design is economically proportioning of concrete ingredients for better strength and durability based on construction site. While the nominal concrete mix may have a higher amount of cement, when it is designed mix, Here nominal concrete mix and design concrete mix are the two types of concrete mix design the cement requirement ...Read More
Slump The slump test is used to classify the workability of the concrete, which governs how easy the mix is to work and handle. It is measured by filling a hollow cone mould which is 300 millimetres high and has a 100mm diameter at the top and 200mm at the bottom with concrete, compacting it and then removing the cone.Read More
