CEMENT & CONCRETE

Cement and concrete is widely used in the construction industry for it’s durability and hardness. Cement and concrete are made from grinding down materials like limestone, chalk and other rock-like substances. The process of making cement also involves controlling the amount of calcium, silicon and other materials to create the powdered cement used in construction.

Construction companies want their cement to be the same light grey colour so that paint can easily be applied ensuring a consistent coating. The SABS stipulates the level of whiteness that different grades of cement should be, and this can be measured using objective colour measurement.

At the end of the day, colour is an important attribute of grading cement and it needs to be accurately and objectively controlled. This helps avoid customer complaints and rejections while ensuring that cement producers comply with South African standards.

Objective colour measurement is used in the Cement and Concrete industry in the following ways:

• Measure the colour of raw materials before the cement production process
• Measure and grade cement based on colour
• Reduce customer debates around colour
• Ensure consistency during production
• Save time and money with objective colour measurement
