ST1 – Concrete A low strength (lean mix) ST1 concrete for general 6 units of mm gravel, with 3 units of a grit sand and 1 unit of ordinary »More detailed/5. Application of Different Types of Cement Rapid Hardening Portland Cements Rapid hardening versions of CEM I cements are available. The average particle size is smaller in these cements and they gain strength more quickly than do ordinary CEM I types. They generate more heat in the early stages and can be useful in cold weather concreting.

Portland cement is the most common type of cement in general use around the world as a basic ingredient of concrete, mortar, stucco, and non-specialty was developed from other types of hydraulic lime in England in the early 19th century by Joseph Aspdin, and usually originates from is a fine powder, produced by heating limestone and clay minerals in a kiln to form clinker.

ASTM's cement and concrete standards are instrumental in the evaluation and testing of concrete, cement, and aggregates. Concrete can have different properties depending upon the mixture that is used in creating it, which contains cement, chemical admixtures, and aggregates.

The removal of formwork also called as strike-off or stripping of formwork should be carried out only after the time when concrete has gained sufficient strength, atleast twice the stress to which the concrete may be subjected to when the formworks are removed.

It is also necessary to ensure the stability of the remaining formwork during formwork removal.

Division on setting time of cement is based on Initial setting time of cement and Final setting time of cement. Generally Initial setting is the time elapsed between the moment water is added to the cement to the time at which paste starts losing.

1. RAPID HARDENING CEMENT: Rapid hardening cement is very similar to ordinary portland cement (OPC). It contains higher c3s content and finer grinding. Therefore it gives greater strength development at an early stage than OPC.

The strength of this cement at the age of 3 days is almost same as the 7 days strength of OPC with the same water.The cement shall be ordinary Portland cement, or rapid hardening Portland cement complying in all respects with the requirements of B.S. 12, “Sulphate Resisting Cement”, shall comply with B.S.
