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.

What are the properties of Self-Consolidating Concrete?
Mixing and handling can significantly alter the air content of fresh concrete. Thus, field tests are used to ensure that the concrete has the proper air content prior to placing. Air content can be measured with the pressure, volumetric, gravimetric, or Chace air indicator methods. The pressure method (ASTM C231) is widely used, since it takes less time that the volumetric method. The pressure method is based on Boyle's law, which relates Figure 7.13 Consolidating concrete with an internal vibrator. pressure to volume. A calibrated cylinder (Figure 7.14) is filled with fresh concrete. The vessel is capped and air pressure is applied. The applied pressure compresses the air in the voids of the concrete. The volume of air voids is determined by measuring the amount of volume reduced by the pressure applied. This method is not valid for concrete made with lightweight aggregates, since air in the aggregate voids is also compressed, confounding the measurement of the air content of the…
