Clay or concrete? - Ask bout pv

[Surya Lee]

Hello sir...
can u tell me the strength of clay paving with 100mm thickness??

exactly what is different between clay paving and concrete paving ?

Exactly i am planning to use one of this in Indonesia to build road..

Thanks you all, You are so kind

Clay pavers are not manufactured in 100mm thicknesses: 80mm is the normal maximum thickness. 100mm units could be manufactured, but as they are non-standard, I have no data for them.

The differences between clay and concrete pavers are explained on the main website, on the Choosing blocks page.

[Surya Lee]

Thanz a lot.
Can the clay pavers which had 80mm thickness used for port or highway?Is it strong enough?

[Tony McC]

65mm clay pavers are normally used on low-speed carriageways, such as pedestrianised town centres. *0mm pavers are 'special order' and tend to be used for applications such as Bus lanes.

I'm not sure about suitability for ports, which normally use a 100mm concrete paver. You'd need to check individual pavers with the manufacturers.

[Surya Lee]

ok..
Thank you for your information and attantion.

In my oppinion, clay paving and clay brick is the same material.Izzit??
If i not wrong the different is clay brick can be use to build house and clay paving used to build road.

[Tony McC]

They are made from the same base material, a clay, but the requirements of clay pavers and clay facing/engineering bricks are slightly different, so, in some cases, different clays, or blends of clays are used.

Hmm...Thanks...
Can I produce paving blocks using only cement and soil(not clay) only?By using hydrolic press mechine.
Is it strong enough?

[alan ditchfield]

This is not possible, the clay block are baked not mixed with cement, and true soil is not at all similar to clay even though it may have some clay content in it. I am sure Tony can give you a more defined explanation on this but i will be suprised if his answer is not the same.

Concrete pavers require a carefully controlled ratio of portland cement, aggregates, sand, water and admixtures mixed to gether and compressed to a minumum 8000psi. A new state of the art paver plant goes for about U.S. $12 million-20 million start up capital.

So, if you can find a way to make high quality pavers with a hydraulic press, please call me, I'm looking to start my own block company! LOL

Believe it or not, you can actually buy moulds to make individual wet-cast pavers in various sizes and shapes, (you can even make fish pavers) but I'd limit making those kinds of pavers to a hobby, because they are going to be worthless unless you plan on never walking over them.

[Surya Lee]

swt.
My hydrolic mechine press 60tons to the paving blocks.So the thickness from 130mm reduce to 70mm.It makes the paving blocks very strong and firm.Really..
The mechine is diffrent with baked ones.This mechine is the latest and newest mechine.If you interested you can call me.Maybe you can start a business too.:laugh: :laugh:

[Surya Lee]

here more detail
Our mixture is 100 kg soil+150kg sand (get from river)+62.5kg cement=62 pieces(215mm[length] x 100mm[width] x 100mm[depth])

The hydrolic mechine press with 60 tons per piece.After 24 hours,we pour water to the paving.
We already test it in labotarium and the strength is about 40mpa-50mpa.


Can you give me some suggestion?

Is there any reason why an FL clay brick cannot be used instead of a clay paver?

I want to create a brick path in a cottage garden and most pavers do not look "rustic" enough. Is there a risk of FL bricks spalling if laid on sand and haunched?

Grateful for any help on this.

Facing bricks are intended for walls. Although they may have sufficient frost resistance, they have not been assessed for permanent contact with damp ground and they have not been manufactured to cope with even modest levels of foot traffic, so there is a problem with abrading.

Although some facing bricks could be used for light use paving projects, it's impossible to say that any FL standard brick would be suitable, and I would never recommend their use. Horses for courses, as they say.

There are hundreds of different clay paviors available and I'm sure there must be at least one that looks sufficiently 'rustic'. Have you considered the Barn Pavers from Baggeridge, or the Van Dyck range from Blockleys?
