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.

Although the constituents of concrete (aggregate and hydrated cement paste) behave in a linear elastic manner if stress is applied to them and the resulting strain is measured, concrete is not a linear elastic material throughout its entire stress-strain curve. What is the main reason for the deviation from this behavior?
