One thing about spending less cash when you are handling a building project is knowing what is required, in what quantity and quality and then having the right hands to handle these without wasting much or any at all. For this reason, i will be Discussing on How to Calculate Materials Required to Mold 3500 Blocks.

On this article, i will be using a 6 Inch block as case study, this is because i see a lot of builders using 6 inches blocks except those building anything above a storey building. Do not forget that in a building project, you’re faced with making decisions such as whether or not to buy or mold your own blocks.

Whether you buy from block industries or mold your own blocks, do not forget to ensure the blocks are strong enough to provide you the strength required as prescribed by the standards in your country.

In Nigeria, a 6 Inch Block (450mm x 150mm x 225mm) is used in various aspects of building construction. Some builders actually use it for septic tank construction also.

## Properties of 6 Inch Block

A 6 inch block has a length of 450mm,

it is 150mm wide and

225mm high

Having known the properties of a 6 inch block, lets talk about the materials required to mold at least 35 pieces of it.

Note: Number of Blocks = 35 pieces

Standard: 1 Bag Of Cement To Produce 35 blocks (Solid only)

## How to Calculate the Volume of a 6 Inch block (Solid Only)

In order to be able to calculate the volume of a 6 inch solid block, we need to understand its dimensions

Length = 450mm (0.45m)

Width = 150mm (0.15m)

Height = 225mm (0.225m)

Now we quickly multiply all the dimensions in order to obtain the volume of 1 6 inch solid block

Volume of Block = (0.45 x 0.15 x 0.225) = 0.0152m^{3}

Next we estimate the volume of all 35 blocks we are required to make by multiplying the volume of each block by 35

Therefore, the volume of 35 6 inch blocks would be

(35 x 0.0152) = 0.535m^{3}

Having known the volume of all 35 solid 6 inches block, lets now calculate the volume of sand required to make these blocks

## How to Calculate the Volume of Sand required for 35 solid 6 inch Blocks

The Mass (M) of 1 bag of cement is 50kg Right?

The density (D) of a bag of cement is 1440kg/m^{3} right?

Lets assume the Volume (V) is unknown and marked x

But Density = Mass/Volume

D = M/V (kg/m^{3})

Where D = 1440kg/m^{3}

M = 50kg

V = ?

Therefore 1440 = 50/v

1440v = 50

v = 50/1440

So V = 0.034m^{3}

### The Volume of a bag of cement is 0.034m^{3}

Because we are still on site and may not have all necessary equipment at hand, i will like to make it clear that the volume of a wheelbarrow is 0.065m^{3} (unheaped).

But it takes 2 x 50kg bags of cement to fill a wheelbarrow.

So how many wheelbarrows of sand is required to make 35 blocks from a bag of cement?

lets not forget that the total volume of 35 blocks is 0.535m^{3}

lets assume the number of wheelbarrows of sand required is x

Therefore, we will need (1 bag of cement) + (total volume of sand) to make a total volume of blocks required

but Volume of bag of cement = 0.0347

Volume of sand required = x(0.065)

volume of 35 blocks = 0.535

Therefore, (0.0347) + x(0.065) = 0.535

x(0.065) = (0.535 – 0.0347) = 0.5003

0.065x = 0.5003

x = 0.5003/0.065

x = 7.7 unheaped wheelbarrows of sand

Therefore the volume of sand required for 35 solid 6 inches blocks = 7.7 x 0.065 = 0.0500

Therefore, in order to make 35 6 inches blocks, you’ll need

1. **1 Bag of cement (50kg)**

2. **7.7 wheelbarrow trips of sand or 0.50m**^{3}

### But what if you had need for 3500 blocks?

So if you had to make 3500 blocks, here are the materials you’ll need

Remember that it takes 0.50m^{3*} of sand for 35 blocks

This means you will need (3500/35) x 0.50 = 50m3 of sand (about 13 trips of sand for 3500 solid 6 inches blocks)

**Since a bag of cement makes 35 blocks, you will need 100 bags to come up with 3500 blocks**

Well, from this post on *How to Calculate Materials Required to Mold 3500 Blocks*, we have been able to show the steps to calculate the volume of sand required to make 35 6 inch solid blocks which we accomplished by first calculating the volume of each block.

We also calculated the quantity of sand required for the 35 blocks as well as that required for 3500 blocks.

Having studied **How to Calculate Materials Required to Mold 3500 Blocks**, i therefore put it to you that you can estimate the materials to required to make as many blocks as you’ll require for any building project with a few exceptions!

Write more, thats all I have to say. Literally,

itt seems as though you relied on the video to

make your point. You clearly know what youre talkjng about, wwhy thjrow away

your intelligence on just posting videos to your weblog when you could

be giving us something enligfhtening to read?

I feel this is one of the so much mportant info for

me. And i'm goad reading your article. But want to remark on ffew ommon issues, Thee site stye is ideal, the articles is really great :

D. Good activity, cheers

I wonder what video you're talking about sir! Mind you over 80% of what you read here are personal experiences.

Woah! I'm really digging the template/theme of this site. It's

simple, yet effective. A lot of times it's hard to

get that "perfect balance" between user friendliness and visual appeal.

I must say that you've done a excellent job with this.

Additionally, the blog loads super quick for me on Firefox.

Superb Blog!

I learnt a lot from this. Thank you so much.

You are much welcome sir

This is my first time visit at here and i am actually

pleassant to read everthinng at one place.

Very good post! We will be linking to this particularly great article on our site.

Keep upp the great writing.

I'm truly enjoying the design and layout of your website.

It's a very eeasy on the eyes which makes it muh more enjoyhable for me

to cme here and visit more often. Diid you hire out a developer

too create our theme? Outstanding work!

Thiis web site really has all of the info I needed concerning this subject and didn't know who

to ask.

Glad you found us useful sir

Hey there, I think your website might be having browser compatibgility issues.

When I look at your website in Opera, it looks fine

but when opening in Internet Explorer, it has some

overlapping. I just wanted to give you a quick heads up!

Other then that, excellent blog!

Not really, i think you are using an old version of internet Explorer.

Download and install Microsoft Edge and check it out!

Post writing is also a excitement, iff you be familiar with after that you

can write otherwise it iss complicated to write.

What's the mix proportion…it should be really taken into consideration

It's fantastic that youu are getting thougfhts from this pieche of writing as well as from our discussion made here.
