Concept explainers

Types of Cement

Cement is a fine mixture of limestone, chalk, or marl and clay which when mixed with water, becomes compacted due to the formation of strong molecular bonds. Due to hydration, cement turns into a hard mass when left for a sufficient amount of time upon mixing with water. The water turns the cement compounds into gel-like submicroscopic particles having higher surface areas. It is due to the hydration properties of cement, they are often known as hydraulic cement. For instance, Portland cement is a popular example in this category.

Four standard mortar cubes were made using nonpotable water available atthe job site, and four others were made using potable water. The cubes weretested for compressive strength after 7 days of curing and produced the failureloads in kilograms shown in Table P6.24.Also, the Vicat test was conducted on the cement paste made with the ques-tionable water and showed that the set time is 0.5hour less than the set timeof paste made with potable water. Based on these results, would you acceptthat water for mixing concrete according to ASTM standards? Explain why.
