Low Heat Portland Cement

IS Standard : IS 12600: 1989

Compared to ordinary Portland cement, Low Heat Portland Cement (LHPC) is a specific variety of Portland cement that is intended to produce less heat during the hydration process. Clinker, the main raw material used in the creation of cement, is chemically altered in order to create this cement.

The lowered heat of hydration is the primary feature of Low Heat Portland Cement. In the process of making concrete, ordinary Portland cement and water undergo a chemical reaction known as hydration. As the process proceeds, heat is produced; this is referred to as the "heat of hydration." Thermal cracking can occur in some building applications due to overheating, particularly in big concrete structures. Portland cement at low heat is utilized to lessen this problem. This cement is distinguished by a larger percentage of dicalcium silicate (46 percent) and a lower concentration of tricalcium aluminate (C3A) (C2S).

In order to make low heat Portland cement, calcareous and argillaceous materials must be completely mixed with other components that contain silica, alumina, or iron oxide. Following the burning process, materials may only be added in the form of gypsum, water, or both. Additionally, air-entraining agents may be added up to 1% of the total.

According to IS standard IS 12600: 1989, all low heat Portland cement is included in the obligatory ISI Certification Scheme. 

This product must have the ISI Mark on it in order to be sold in the Indian consumer market or be allowed to be imported or exported.


About ISI / BIS Certification

Indian Standards Institute, or ISI was renamed the Bureau of Indian Standards (BIS) in 1987. The official mark that the Bureau of Indian Standards provides for manufacturers of various goods is the ISI Mark. It is used to indicate compliance with Indian standards (IS) set by the Bureau of Indian Standards (BIS) and has been used as a conformity marking for industrial products. Manufacturers received permission from BIS to use the ISI Mark on items that comply with relevant Indian requirements through the product certification program. 

Only manufacturers (domestic or foreign) who produce the finished product will be awarded ISI Certification. This will not be given to any product importers, traders, dealers, or distributors.


Documents Required for ISI / BIS Certification

The following documentation is required to get an ISI certification:

Process of ISI / BIS Certification

There are two approaches for Indian manufacturers to become certified with the ISI Mark:

  • Regular Procedure
  • Simplified Procedure 


Regular Procedure

With the possible exception of cases deemed "All India first," which might take up to 180 days, the licensing procedure is expected to be finished in 120 days. This timeline starts on the day the application is received, assuming that at different points in time the documentation, unit assessment, and product conformance are all deemed acceptable.

Step 1: Manufacturing Unit Customization in Compliance with Applicable Indian Standards

  • Identifying the applicable Indian Standard
  • Establishing in-house testing facilities as per the Standard's requirements

Step 2: Submission of the Application Form

  • Preparing an Internal Test Report for the product by the relevant Indian Standard
  • Compiling all necessary documents
  • Completing the Online Application Form
  • Online payment of application fees directly to BIS
  • Submitting hard copies of the Application Form with all enclosures to the relevant Branch Office (BO) of BIS

Simplified Procedure

This is a much faster process than the standard procedure. After a factory inspection is deemed satisfactory and the initial evaluation establishes that the sample complies with the applicable Indian Standard(s), the license application process is expected to be finished in 30 days.

Step 1: Adapting the Manufacturing Unit to Comply with the Relevant Indian Standard

  • Identifying the applicable Indian Standard
  • Establishing in-house testing facilities to meet the Standard's requirements

Step 2: Sample Testing

  • Obtaining the necessary certificate for raw materials (Material Test Certificate - MTC)
  • Conducting product sample testing at a BIS-recognized testing laboratory
