What is CSA A3000?
CSA A3000 : Cementitious materials compendium.
What is cementitious surface?
Cementitious coating refers to a coating that contains Portland cement as one of its components and is held on the surface by a binder. Proper selection of materials and their correct application is required for an effective cementitious coating.
What is cementitious material used for?
Supplementary cementitious materials can be used for improved concrete performance in its fresh and hardened state. They are primarily used for improved workability, durability and strength. These materials allow the concrete producer to design and modify the concrete mixture to suit the desired application.
What is meant by cementitious?
: having the properties of cement cementitious mortar.
What are supplementary cementitious materials?
Supplementary Cementitious Materials (SCMs) are materials that, when used in conjunction with portland cement, portland limestone cement or blended cements, contribute to the properties of hardened concrete through hydraulic and/or pozzolanic activity.
What is a cementitious surface?
What is cementitious mortar?
Cementitious mortar is a cement-based binding material used to stick building blocks such as bricks, stones and other similar building materials together. It is composed of sand, a cement binder, water and possibly other additives. Most commonly, cementitious mortar is used when constructing walls, fences and walkways.
What is reinforced concrete structure?
The reinforced concrete structure refers to the members, such as beams, boards, columns, roof trusses, consisting of concrete and steel bars. In these structures, the steel bars are enwrapped by concrete, but their mechanical properties will still lose due to the fire to destroy the whole structure.
Which is the fifth edition of the cementitious materials compendium?
Preface This is the fifth edition of CSA A3000, Cementitious materials compendium. It supersedes the previous editions published in 2013, 2008, 2003, and 1998. Significant changes from the previous edition include the following: a) Ground glass pozzolans have been introduced as new supplementary cementitious materials.
What are the different types of cementitious materials?
There are two types of cementitious materials: hydraulic cement and supplementary cementitious materials (SCMs). Hydraulic cements set and harden by reacting chemically with water.
What kind of cement is used in concrete?
Portland cement is the most common hydraulic cement. SCMs are used in conjunction with portland cement in concrete mixtures to improve the workability of fresh concrete and reduce thermal cracking in massive structures by reducing heat of hydration.

What kind of fume is used in cementitious material?
Typically, silica fume is used between 5% and 10% of the total cementitious materials. Another group of SCMs are natural pozzolans, which are produced from natural siliceous and aluminous mineral deposits, including metakaolin (calcined clay), calcined shales, rice husk ash, diatomaceous earth, and volcanic ash.
