Hi good people

Of late,several buildings have some hollow blocks evenly arranged before the slab is laid. I understand that they reduce the cost of laying a slab by almost half. Can anyone please shed some light on this?

Thanks fantony

The span will be around 12 metres. Will gather more info on this. I understand that they are made by clayworks. However,i am made to understand that they have to make the beams too.

Good people here sound enlightened in matters building..So am looking for ideas for a final year undergraduate project in Bsc civil eng.,At the end of it i need to have come up with a solution to an existing problem in the industry..Am Hoping to do something really original and preferably commercially viable.i think u guys out there might have an idea of something u wished worked differently,or could be done or you just wonder if an idea could work. Your ideas are most welcome.

what problem did you want to solve with your education from the outset?

- respectable credentials
- aviod / get out of poverty
- help the society
- satisfy your curiosity

depending on the above you might just identify the area of 'study'.











Essentially,you might be in that class for all of the wrong or right reasons. sit down and ponder about your preferred future. And what you want to spend your time doing with it.

it doesn't make sense to study roads when your entire constituency has only one river that dries up even in wet weather.

or study water; while you think showering is not essential.

or study roads yet you dont like the sun and/or wet weather.

or materials while you know all the best labs are on another continent and whatever your findings will be were in std 8 chemistry report in japan.

or management while all you wish in your life is to be left alone.

Mmmh,didnt know we had structural Engineers as members of SK
@Tito,what do you mean that the beams too have to be made by Clayworks,thats CRAP,the beams are cast insitu,all you need to know are the hollow block dimensions and loading regime i.e what kind of load are you going to subject the suspended slab to.
If you geeky enough,try going through BS 8110:1 1997 clause 3.6. Good luck.

There are different technologies to construction. i believe what tito meant was using 'precast caly hollow block cast on the ground and erected.To elaborate further,
You arrange 1row of the clay hollow blocks on the ground . The blocks have a groove at the top where you place a steel bar running through. you then place meshwire above the blocks and lay about 50-75mm thick concrete overlay on top. what you get is a 'precast beam,which you can place on top of a beam. The beams are place abutting each other and when the slab is all covered you can lay 50 mm thick concrete. this is deemed a cheap technology and faster method of construction.
