Contact2017. 11. 25. CHEMICAL ADMIXTURES: Chemical admixtures are materials in the form of powder or fluids that are added to the concrete to enhance the properties of the concrete. The common types of admixtures are as follows: Accelerators Retarders Air entraining
Contact2017. 1. 22. RECENT ADVANCES. IN CONCRETE TECHNOLOGY Merits of concrete Ingredients of concrete are easily available in most of the places. Unlike natural stones Concrete is free from defects and flaws. Concrete can be manufactured to desired strength with economy. Thedurability of concreteis very high. It can be cast to any desired shape.
Contact2016. 12. 16. Admixtures are ingredients other than portland cement, water, and aggregates. Admixtures are added to the concrete mixture immediately before or during mixing. The use of admixtures in concrete is now widespread due to many benefits- It reduces the amount of water requirement in Concrete. It control the setting behavior of Concrete. It also improves the workability, durability & strength of the Concrete.
Contact2019. 1. 3. 1.1 CONCRETE DEFINITION AND HISTORICAL DEVELOPMENT Concrete is a manmade building material that looks like stone. The word “concrete” is derived from the Latin concretus, meaning “to grow together.” Concrete is a composite material com-posed of coarse granular material (the aggregate or filler) embedded in a hard matrix of material
