Practically weight of 1 cum M:15 concrete mix is more than M:20 concrete mix. Do you agree? I'm asking this because i have seen this in my batching plant after loaded on transit mixture. Let me know what you think. Thank you. By, Kunal Kumar Gupta

I'm currently working on a new construction site and facing problem measuring the level of the construction. My question to all pro civil engineers that what technique could be used to measure the level in a building construction?
The main steel is reinforced in the shorter direction for slabs in building construction. Why it is not done in the longer direction?
Where 'Grillage Foundation' is used? What are the advantages of using Grillage foundation?

I'm a student so am still learning, anyway I think I know what a continuous beam is: a beam that spans more than two supports. I have a project to design a building however going through lecture notes for preliminary design I have come across this:
'Based on the practice of experienced designers a number of “rules of thumb” have been suggested to propose the initial size of members. For instance some designers use the following “rules of thumb” for the preliminary sizing of RC beams:
for simply supported beams: h>=L/16
for beams with one end continuous: h>=L/18.5
for beams with both ends continuous: h>=L/21
for cantilever beams: h>=L/8
where h= height of the beam, L= length of span'
Now I can't seem to find anything anywhere else that differs between continuous beams, and nor can I think what it might mean. I feel stupid asking this but no one seems to know and my lecturer has been ignoring me :/ I possibly thought he may not mean a continuous beam as such but be referring to an overhang but given that the building I am designing is a general grid layout I don't think anything is overhanging so am just a bit puzzled. Any help would be greatly appreciated :)

I'm stuck with the question. Where does the point of con-traflexture occurs in a loaded beam? Is it the place where bending moment is minimum or whether bending moment is maximum?

I heard the word 'hacking' from a civil engineer friend but couldn't remember the exact meaning of the term. What does it mean?

The title of our topic would be: "The Distributing of Fire Rating on reinforced Concrete structure due to Elevated Temperature"
SHORT DESCRIPTION: This study aims to produce a reference table of the initial rapid assessment of the flexural serviceability of the reinforced concrete beam in a residential-type structure. The RC beams will be subjected to fire with elevated temperature on certain time durations. The data that will gathered will be used as the basis in designing structures considering the possible effects of fire in the resisting capacity of reinforced concrete beams.
is this study valid to be defended? Thank You. -from the Philippines.
