Please I would like to know the ratio of cement to sand and gravel concrete mix using the ratio 1:2:4 and 1:3:6.....like in 1:2:4 I heard it's a bag of cement to two wheebarrows of sand and 4wheelbarrows of gravelani don't know how true it is.
Secondly,pls how many headpans of sand is in a wheelbarrow and how many wheelbarrows of sand is a tonn.......thanks and God bless

Its ratio 1:2:4
1bag of cement to 2wheel barrow of sand and 4 wheelbarrows of gravel.
25 headpans makes a tonne

thanks..God bless

So,does it means two headpans makes a wheelbarrow?because two headpans makes a bag of cement

Approximate. But the basic thing is thatan whichever tools that you want to adopt as a means of measurement, be consistent. If its heapan that you want to adopt, be consistent with it. If its wheelbarrow, be consistent. By so doing, you will be able to control the outcome of your measurement thereby avoiding unnecessary variations that might bring about confusion

This must b a highest order confusion! How come will u say 1:2:4 and equate it to 1bag of cement to 2wheelbarrows just as d number appears! Ain't u using batch by volume?? Is it possible a bag of cement full a wheelbarrow ...unless mayb in lab shar....lol
On site where d real tin happens, a bag of cement is 2headpans and a wheelbarrow is 4headpans. For a bag of cement, u'll b using 1wheelbarrow of sand and 2wheelbarrow of gravel. Do the maths urself and verify it PRACTICALLY! ...*winks*...1Love!

1bag of cement -- 2 headpans !
1:2:4 means -- 2 headpans of cement , 4 headpans of fine aggregate (sand), 8 headpans of coarse aggegate(gravel).

1:3:6--- 2 headpans of cement, 6 headpans of fine aggregate (sand), 12 headpans of coarse aggegate(gravel).
4headpans = I wheel barrow, 20 bags of cement-- 1 tonnage of cement, 1bag of cement --50kg, 1 headpan full-- 25kg, 40 headpans full--1 tonne;

There are other mix ratio depending on structural elements to be built and workability of fresh concrete .

The info here has been of help.... Thanks

How many shovel makes an headpan please

Please for a normal pillar for the building where the blocks will be joined and that of the front of the building, what ratio is advice.
Kindly assist.

Use 1:2:4

Use 1:2:4

Many thanks.
Please I have three questions, please what quantity of sand, cement and granite/gravel stones will be required
1. To make a pillar that will be between block joining
2. To make lintel on 9 inch block
3. No of cement to lay 100 blocks

3--2.5--3 bags is enough, some use 2bags to lay 100blocks.

You may need to learn how this quantity is calculated from diagrams ok. It will help in future.

Whatsapp me let me explain some things to you .

Amastermovic:


Use 1:2:4

Just like that,

The way you folks pick up ratio like ...

Do you know they type of building.

No wonder columns buckle at will

firstly Engr. the minimum mix ratio for a reinforced concrete is what I provide to the op and he's not employing d service of a structural engr and from his post you know he's building a bungalow or most a 2 storey building which 1:2:4 is still likely to work or work self

The buckling issue engr is caused when u didn't factor your load rightly and the member can not resist d forces here I didn't choose the column size nor reinforcement...
columns does not buckle by will sir. you can only say next time be sure to ask for the intended use of d structure and conditions

Thank you Engr morning

What's the intended use of the structure let me know to help you accordingly. if you have d Architectural drawings it will go along way..

check my signature and contact me on whatsapp or upload it here If u wish

I intend to out up 11 (two front pillars inclusive) pillars so the concrete parapet does not fully rest on the blocks.

Sorry, please I don't understand. Is it 3 bags per pillar or what. Kindly assist with your WhatsApp number to assist

Thank you for the feedback ,
Dont be offended anyway.

2.5 --3 bags of cement i mean to lay 100blocks.

A bag of cement to lay 50numbers of 9inches block

for a column of 225by225 each use....

cement 16 bags
gravel 35 wheel barrow
sharp sand 17.5 wheel barrow

I estimated using wheel barrow to measure the materials needed incase u still have materials available at ur site because in tonnes its small..

though I don't know what stage of work u r presently if you r just starting adding d footing German floor etc to the estimation will increase it... if you already built and only want to insert d columns estimating the materials will give a better view of the materials like 5tonnes which can easily be got.. I hope you understand this... and my bozz koolengrtimmy will finish d rest for u via whatsapp..

Thank you boss , this is very detailed.

Dear Good people,

Please assist with materials for concrete parapet that is moderate for a building dimension of 19.8m by 13m

I would also appreciate if you can give the number of parapet curves in a 1 by 12 plank.

Thank you as I await feedback.
