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.

1. Question 2 Refer to Appendix A for tables and equations to be used. Use the CNCI method. You are given the following design parameters for a concrete mix: The compressive strength of the concrete mix must be 40 MPa after 28 days. The cement that is going to be used is a CEM I 52.5 with a relative density of 3.14. The stone available is a 19.0 mm stone with a dry compacted bulk density (CBD) of 1780 kg/m³ and a relative density of 2.24. An average, natural sand with a fineness modulus of 2.45 and a relative density of 2.86 is going to be used for the mix. The slump on site is specified as 75 mm. The concrete is going to be compacted by moderate vibration on site. Calculate and show the amount of water, cement, stone and sand that is needed to make up 1 m of concrete mix as specified above. water requirementinliters w:c ratio • Cement content (kg/m3 of concrete) = • Mst = CBDS: (K – 0.1 FM) M.
