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.

Question

mix with 8.1 kg of cement and 0.9 kg of fly ash?
OA 4.5 mL
O B) 6 mL.
OC 12 ml
OD) 9 mL
During Lab 9, a 150 mm x 300 mm diameter cylinder was placed horizontally in the
Universal Testing Machine and a load was applied. This test was done to determine
the
strength of the cylinder.
O A Shear
O B) Tensile
OC) Compressive
OD) Torsional
The estimated batch weights required for 1 cubic meter a concrete mix are: water =
