The mix ratios for C20, C25, C30, C35, and C40 concrete are as follows: C20: 1:2:4 C25: 1:2:3 C30: 1:1.5:3 C35: 1:1:2 C40: 1:1:1.5 The numbers represent the ratio of cement, fine aggregates, and coarse aggregates, respectively. For example, in C30 concrete, there is 1 part cement, 1.5 parts fine aggregates, and 3 parts coarse aggregates.
Genral concrete term I used for the concrete which we used generally for structural elements with compressive strength 35mpa and slump values are from 75mm to 125mm.
@@CivilEngineerAtSite as you said General concrete 75mm to 125mm slump value and wet 160mm to 240mm as we know high workability may affect the strength of concrete if the workability goes up the strength will be go down but you said the strength will be same 35mpa in both cases how we will maintain the same strength of both concrete sir.
Bro AOA If HR call to candidate for initial interview and ask about expected salery and about joining...then how many chances for technical interview or again call from HR for interview?????
@@CivilEngineerAtSite Thank you so much that you have reply me on good manner. C's for lean concrete is 2000 psi(14mpa) for pre-cost concrete is 5000 psi(35mpa) And for cast in place concrete 4300 psi please study SAES-Q-001
Highly anticipated sir
Good
Very nice
Waiting
Nice information. Please continue this series about these technical questions and answers.
In Shaa Allah
Thank you so much brother
Indeed you are doing very great job for us .
Appreciate all ur videos Jazakallah 🥰
Thank you dear
I think astm c1064 say there temperature 18 to 32 mostly we are focusing on site
Well done brother keep going on❤
❤❤❤❤❤

Behtreen 👍
Zbrdast video da ror me
Continue sir
Sir if client said that we don't do concrete at night time.what we do at that time.and what we do maintain concrete temperature
You have to follow client instructions.
Bro don't mint but for structure like slab , beam foundation etc C25, C30 are used C35 is used for Precast pre stressed structural members.
Who told you this?
we use M-20 concrete use in RCC structure but PCC we used M-10 or M-15
In pcc we are using C16 in Saud Arabia who’s compressive strength is 16 mpa
Sir in aramco slump value should be 150 +- 40 ? Correct or not kindly guide?
Dear depends on mix design some times
In previous one video you mentioned 1.5 meter maximum height for concrete falling and here mentioned 1 meter.
Bro 1 meter is standard and in Neom 1.5 meter is acceptable
@@CivilEngineerAtSite Noted,
Thank you for your kind response once again
We are also following 1.5 m
Pls info me sir.. recently vacancy of civil engineer in Saudi arebia
What is the difference between wet and general concrete as you said in the vedio sir?
Genral concrete term I used for the concrete which we used generally for structural elements with compressive strength 35mpa and slump values are from 75mm to 125mm.
Wet concrete are high workability concrete with compressive strength 35mpa and slump values 160mm to 240mm.
Difference on the basis of slump test
@@CivilEngineerAtSite General concrete is not a wet concrete?
@@CivilEngineerAtSite as you said General concrete 75mm to 125mm slump value and wet 160mm to 240mm as we know high workability may affect the strength of concrete if the workability goes up the strength will be go down but you said the strength will be same 35mpa in both cases how we will maintain the same strength of both concrete sir.
Dear respected Engineer the temperature ranges is from 12 to 32 degree centigrade am I right
You are talking generally like summer and winter season. But as I mentioned it’s for summer
Thank you soo much dear respected
please share the standard book in pdf format
Brother please write these questions and share
Can you send me the details for wet concrete as you said in video ASTM C143 SAY
WET CONCRETE RANGE 160-240MM
waiting
THANK YOU

Bro AOA
If HR call to candidate for initial interview and ask about expected salery and about joining...then how many chances for technical interview or again call from HR for interview?????
Depends on your response to the questions
Dera dera manena Sir
Asalamulaikum brother i have completed my bachelor degree in civil recently with 1 month experience only can i get job in saudia arabia and how ?
No minimum 5 years experience
Brother don't mind u r guiding people on wrong way please study a lil more.
What is wrong here ? Correct me, you commented that I am guiding people wrong? Please tell me
What’s wrong here?
I will mind it dear.
@@CivilEngineerAtSite Thank you so much that you have reply me on good manner.
C's for lean concrete is 2000 psi(14mpa) for pre-cost concrete is 5000 psi(35mpa)
And for cast in place concrete 4300 psi please study SAES-Q-001
And temperature range from 10 to 35
But you said 26 to 35
In summer
Study ASTM C 1064-86
I need structure drawing for practice
I have uploaded video on this topic. check playlist about drawings.
Improve your English language, please
Ok. Bro 😎
Thoda slowly bolte
Next time tez Bolonga
Kya bolta ho kuxh kuch v samajh ma nahi aata
🤔 q ?
Mee too
