14. Technical Names of Curves on Roads
Our civil engineers know that there are 4 forms of street curves: easy, compound, inverted and divergent. We all know the way to use the proper equations to design a street alongside every of those curves. Not solely that, however we all know the way to calculate the slope at which the street should curve to forestall vehicles from sliding off the street.
13. Concrete by no means dries

As a civil engineer, I in all probability love concrete greater than something. It’s grey and mushy, then quickly it turns right into a stable rock. If love does not appear like that, I do not know what’s. Nevertheless, in all seriousness, we all know how dry concrete is in some unspecified time in the future in its curing cycle. We additionally perceive that concrete technically continues to dry and strengthen all through its lifetime.
12. Particle sizes for various soil sorts
We all know small dimension variations between silt (.05 to .002 mm), sand (2 mm to .05 mm), and clay (< .002 mm). A few of us could not even should calculate the particle dimension, we will solely see and know the soil. With these factors of information, we will decide what combos of soils make for a greater basis and what must be finished to make the land extra appropriate for building.
11. Why are there gaps within the street on bridges and in tracks on railways?
Civil engineers know that growth joints are wanted in roadways and railways to permit the steel to broaden and contract with temperature. If these usually are not constructed into the infrastructure, roads and railways can fail or bend.
10. There’s a enormous distinction between concrete, cement and mortar
I do not know what number of occasions I’ve heard somebody confer with cement as concrete – the within of me simply cringed. We all know that concrete is a cement with a fantastic and coarse combination and that mortar has a excessive focus of cement with further fantastic aggregates like sand. Cement is the one binding materials. Civil engineers in all probability additionally know that vehicles carrying concrete usually are not known as cement mixers, which is mistaken anyway, they’re known as transit mixers.
9. How briskly is it for sewage in a pipe

One of many much less glamorous components of civil engineering is the way to deal with wastewater. We all know that sewage has to circulate over 3 toes per second in horizontal pipes. We additionally know that if sewage flows very quick, comparable to greater than 12-18 toes per second, harmful gases could be created and everybody has a foul day. There’s much more science round dealing with your waste than you suppose.
