Supplementary cementitious materials are the mineral admixtures consisting of powdered or pulverized materials which are added to concrete before or during mixing to improve or change some of the plastic or hardened properties of Portland cement concrete.

What is the BS concrete design mix for class 20?

40 20 concrete design mix is the water to cementitious materials ratio. This is what determines the class of the design mix.


How much cement required in 1 Quebec meter concrete?

In Quebec, a cubic meter of concrete typically requires about 300 to 350 kilograms of cement, depending on the specific mix design and intended application. This is generally around 10-12% of the total volume of the concrete mix. The exact amount can vary based on factors like desired strength, workability, and the inclusion of additives or supplementary cementitious materials. Always consult local standards and guidelines for precise calculations.

Can Cement be put on top of cement?

If the question means: "can new concrete or mortar be put on top of old concrete", for example to restore a reinforced concrete structure, the answer is NO. You will have to use proprietary non shrinking cementitious mortars (say Emaco or similar), otherwise the patch will fall to the ground ! vAR - Roma, Italy Yes you can! However first check the pH of the concrete to insure it is no higher than the number 9ph. If pH is between 7.5 and 9ph you are ready to repair. Apply a densifier to the concrete and resurface with a high performance repair material or overlay. JH Super-Krete


How is concrete made?

Concrete is made from cement and other cementitious materials such as fly ash and slag cement, coarse aggregate made of crushed stone, fine aggregate such as sand, water, and chemical admixtures. For more information please visit the related link.

Can Bauxite be used in concrete?

Yes, bauxite can be used as a raw material in the production of cement and concrete. It can be added to concrete mixes to improve the strength and durability of the final product. Additionally, bauxite residue, a byproduct of bauxite processing, can also be used in some concrete applications as a supplementary cementitious material.

What is micro concrete?

Microconcrete is a dry ready mix Cementetious based composition formulated for use in repairs of areas where the concrete is damaged & the area is restricted in movement making the placement of conventional concrete difficult., It is supplied as a ready to use dry powder which requires only addition of clean water at site to produce a free flowing non shrink repair micro concrete. This is a cementitious material, with additives, which impart controlled expansion characteristics in the plastic state with reduced water demand.

Is concrete a compound an element or a mixture?

Concrete is a composite construction material, composed of cement (commonly Portland cement) and other cementitious materials such as fly ash and slag cement, aggregate (generally a coarse aggregate made of gravel or crushed rocks such as limestone, or granite, plus a fine aggregate such as sand), water and chemical admixtures.
