13 Types of Cement and their Uses in Concrete

Rapid hardening cement is used in prefabricated concrete construction, road works, etc. 4. Quick setting cement. The difference between the quick setting cement and rapid hardening cement is that quick-setting cement sets earlier. At the same time, the rate of gain of strength is similar to Ordinary Portland Cement, while quick hardening cement gains strength quickly. Formworks in both cases

Concrete Vs. Asphalt Roads — Which Is Better? –

Like concrete, asphalt is made using aggregate. Its binder, however, is bitumen, a dark, sticky substance derived from crude oil. When roads, parking lots or driveways are built using asphalt construction, hot asphalt (bitumen mixed with fine aggregate) is poured onto a bed of heavier aggregate and then pressed into it with a steamroller.

26.02.2020· In the construction of flexible roads mainly bituminous materials are used. Defects in the flexible road can be seen on the surface if there is a settlement of the lower layer. The design of flexible pavement is done by considering the overall performance of the road, and the stresses produced should be kept well below the allowable stresses of each road layer.
