Cement – 611 pounds; Sand – 1450 pounds; Stone – 1600 pounds; Water – 33 to 35 gallons; So, you can see more cement and less sand is needed to get stronger concrete mix, which is ideal for driveways, pool decks, exterior patios, sidewalks and commercial garages. Irrespective of the batch size, it is imperative to keep the ingredients in ...

Apr 27, 2015 · The setting characteristics of Portland cement paste are defined by initial set and final set. Initial set indicates the approximate time at which the paste begins to stiffen considerably. Final set roughly indicates the time at which the cement paste has hardened and can support some load.

Under this circumstances, the low heat cement or low heat portland cement can be effectively used. In low heat cement , ingredients are proportioned in such a way that C3A and C3S are formed in less amount but C2S is formed in increased amount so that C2S and C3S collectively impart the same strength as Ordinary Portland Cement (OPC).

Cement stabilization of soil is done by mixing pulverized soil and Portland cement with water and compacting the mix to attain a strong material. The material obtained by mixing soil and cement is known as soil-cement. The soil cement becomes a hard and durable structural material as the cement hydrates and develops strength.

Geopolymer concrete is considered to be an innovative material that is a viable alternative to traditional Portland concrete or cement used in transportation infrastructures, certain constructions and offshore builds. It is very resistant to several of the durability issues that can cause traditional concretes to crack and crumble.

Soundness of cement: In order to keep cement sound, we need to be careful in some aspects. It is essential that a cement paste, once it has set, does not undergo a large change in volume.
