A reliable determination of the carbon and sulphur content in cement is an essential part of the quality control process. If the sulphur content is too high, the cement could be destroyed as a result of the chemical reaction of sulphuric acid. The carbon content is usually certified as CO2 and sulphur content is given as SO3.

Name * Color test. The colour of the Portland cement should be uniform at the site. The best and preferable … A reliable determination of the carbon and sulphur content in cement is an essential part of the quality control process. If the sulphur content is too high, the cement could be destroyed as a result of the chemical reaction of sulphuric acid.

2- Presence of lumps. 3- Temperature test. 4-Float test. 5- Strength test.

Ordinary Portland cement 43 grade is a moderate strength Portland cement where according to BIS requirement the compressive strength of this cement should not be less than 43 MPa after 28 days. Chemical Composition: The strength is obtained because of high percentage of C3S content about 50%.90-95% clinker is grinded with 4 to 5 % of gypsum to make this cement. Properties : Chemical …

In portland cement manufacturing process, the quality of cement clinker directly affects the quality of the finished product cement. The following are several important factors affecting the cement clinker quality. In the process of clinker production, strict control of these factors can ensure the production of high-quality, high-yield clinker. COMPREHENSIVE QUALITY CONTROL OF PORTLAND CEMENT CONCRETE WITH SEISMIC METHODS. The feasibility of seismic methods for determining the quality and thickness of portland cement concrete layers was recently studied. The study consisted of performing nondestructive laboratory seismic tests on cylinders that were laboratory-cured for 2 to 90 days.
