Magan Agarwal Binani Cement Limited Key factors that control the compatibility between Naphthalene-based super plasticizers and ordinary Portland cements Synopsis: Super plasticizers improve the workability of concrete at low water cement ratio but this workability is sometimes lost rapidly in the first hour after contact between the cement and water. This is especially the case for naphthalene-based and melamine-based superplasticizers when used with the so called incompatible cements. It

the Angel I think the angel was there to heal the child and the people. The child was sick with a temperature. The story says‚ “…the newborn child had a temperature all night…”. The people were sick in the sense that they were treating things that were different from them as animals.

Consolidation of plastic concrete is termed as compaction. In the process of compaction‚ efforts are only directed to reduce the voids in the compacted concrete. Compaction of concrete can be done either manually or mechanically. When it is done manually it is called hand compaction or tamping‚ and in second case it is termed as machine compaction. Hand compaction: Hand compaction is done with the help of steel tamping rods‚ or timber screeds. Marrow and deep members are compacted with tamping

object thereby strengthening it. The idea of pretensioned concrete has been around since the late 19th century‚ but its use was limited by the quality of materials available at the time. It wasn’t until the 1920s that materials of a suitable quality were available in sufficient quantity to allow pretensioned concrete to be used with confidence. The pioneers of this field were Freyssinet‚ Magnel and Hoyer. Description: In pre-tensioned concrete tensile elements such as cables‚ ribbons‚ or rods are clamped

Engineering B45 Concrete Lab Report Introduction: Concrete is a mixture of sand and rock or similar inert material (aggregates) held together by a cementing material. Usually the cementing material is Portland cement‚ but sometimes binders such as asphalt or gypsum are used‚ in which case the concrete may be called asphaltic concrete or gypsum concrete. Properties of concrete are governed not only by the properties of its ingredients (cement‚ water‚ sand‚ and coarse aggregate) but also‚ to a great

introduction of concrete as a construction medium and the true arch as a structural component made it possible for the Romans to build strong‚ elaborate‚ expansive structures that would endure the test of time. Concrete Roman concrete‚ called opus caementicium‚ was made by mixing traditional lime mortar with stone aggregate called caementa. This material used less water and was very thick compared to modern concrete; therefore it was laid rather than poured (Roman Architecture‚ n.d.). Concrete was an important
