Concrete Additives

Concrete Additives Concrete additives are fine materials which are generally added to concrete in significant proportions (around 5–20 %). They are used to improve or obtain specific fresh and/or hardened concrete properties. European Standards lists

Equations of Static Equilibrium Equations of Static Equilibrium: Consider a case where a book is lying on a frictionless table surface. Now, if we apply a force F1 horizontally as shown in the Fig.1(a), then

Self-compacting Concrete: Fresh Properties

TeamCivil Concrete, Materials, Types

Self-compacting Concrete: Fresh Properties Self-compacting concrete has specific fresh state properties which conventional concrete does not have. Fresh concrete properties of SCC are obviously related to its property of self-compactability. Self-compactability in mechanism terms is

Concrete Repair and Maintenance Steps

TeamCivil Repair

Concrete repairs have occurred on Reclamation projects since the first concrete was placed in 1903. Unfortunately, even though the best available knowledge and materials were used, many repair failures have occurred during the 112 years
