Ordinary Portland Cement: Uses, Advantages & Disadvantages

Introduction to ordinary Portland cement: Ordinary Portland cement is one of the most widely used cement. The name Portland cement was given by Joseph Aspdin in 1824 due to its similarity in colour and high quality when it hardened like a Portland stone. Portland stone is white grey limestone within the island of Portland, Dorset.

Characteristics and mechanism of modified triethanolamine

Effects of modified triethanolamine as cement grinding aids on particles characteristics and mechanical property of cement were studied, and its reaction mechanism was analyzed by IR, Zeta potential, SEM, XRD and TG-DTA. The results show that the content of 3-32 μm particles for cement with 0.015% modified triethanolamine(M-TEA) is increased by 12.4%, and the compressive strengths of cement

Rapid Hardening Cement | Properties, Uses, Advantages

The 3 days strength of rapid hardening cement is equivalent to the 7 days strength of OPC when the water-cement ratio for both the cement is taken to be same. The increased rate of strength is due to the fact that higher proportion of tri-calcium silicate (C 3 S) is contained in RHC along with finer grinding of the cement clinker.

How Portland Cement is Made? Manufacturing Process of

Portland cement can be made by following two different processes – a dry one and a wet one. Joseph Aspdin first made portland cement in his kitchen stove in England in the 19th century. Lime and silica make up approximately 85% of portland cement. The materials that are commonly used are limestone, shells, chalk, shale, clay, slate, silica sand, and iron ore. Since limestone is the main
