CONCRETE
Concrete is one of the most important contemporary civil engineering materials. It is a composite construction material formed by mixing an aggregate with cement and water, then allowing the mixture to dry and harden.
RAW MATERIALS OF THE CONCRETE
coarse & fine aggregate
The coarse aggregate are granular materials obtained from rocks and crushed stones while fine aggregate are the sand obtained from river beds or quarries.
cement
The cement acts as a primary binder to join the aggregate into a solid mass.
water
The water is required for the cement to hydrate and solidify.

Great!This information is quite good n helpful to me report.
Thank you.
Wish you can post more information abt building material.

*like* ^^
info n pics interesting..

thanks for your compliment..

Like the content of the blog where construction materials are explained generally in precise way
Somehow I have a question:
What is the relationship between concrete density and concrete strength?

good description with nice picture...

This information give us the basic knowledge about the process of making cement and others. Besides, it is easy understanding by us by providing the picture with the explanation.

Nice background , Nice description ~

This is an awesome place for a layman to learn interesting fact about construction!
By the way, can I have the coffee machine?
^^

thanks~~
the coffee machine u can try to make urself...^^

thanks for your commend.^^

Thanks for the great info in all your posts. May i know what kind of sand did cement made of? =)
13 March 2012 at 04:39
thanks for your commend.
by the way, we will try to update more information about the concrete.
13 March 2012 at 04:47
thanks~~the sand is the silicon dioxide or silica...

which kind of the brick is the cheapest and most expensive?

-> Lim Ooi Yuan aka Iverson D.Yuan
Concrete strength is directly proportional to concrete density. A higher concrete density means that the porous structure in concrete has reduce reduce. This is because the void in concrete has been occupied by hydration product. This hydration product is the main component of concrete strength

Is that concrete harder than brick?
