in a simple way it is the strength of concrete, which it can bear the loads of its specified grade ex C 25 grade can resist the weight of 25kn/m2 after 28days of 60% after 7 days.
http://simscience.org/cracks/advanced/concrete2.html A common mistake people make is to use the words cement and concrete interchangably. It is important to remember that cement is only a component of concrete and concrete is the structural material. The cement used in concrete is not used as a building material because it would be too expensive and not as strong as concrete. So when you see a parking garage, a driveway, a sidewalk or a road remember it is made of concrete, not cement. And, by the way, that funny looking truck is a concrete mixer, not a cement mixer! But, if cement is not concrete, then what is it? Cement is a general name for a material that binds other materials together. Yes, it is another name for glue. There are many materials which we would classify as cements and they are usually identified with certain uses, and can produce different types of "concrete". The type of cement used to make the riding surface of some of our roads (blacktop!) is called asphalt cement. It is a petroleum bi-product, and it binds rock into the road material we call asphaltic concrete.
Cement is called green when it is just poured. It is "green" until it sets up and cures or dries. This will vary depending on conditions. Wet cement has a slight green cast to it that changes to gray when it dries.In addition to consuming considerable amounts of limestone, sand and energy, producing each ton of Portland cement releases one ton of carbon dioxide into the environment. One of the emerging concrete technologies for sustainable development is to use "green" materials for construction. The "green" materials are considered as materials that use less natural resource and energy and generate less CO2. They are durable and recyclable and require less maintenance.
wil or WIL stands for Walk In Linen (Linen cupboard)
It would depend on two factors.. 1. are you mixing the concrete your self or 2. are you buying the concrete pre-mixed Mixing your own concrete by com-binding sand and cement is the way to go as its cheaper. Also by your sand in large loads as again its much cheaper than buying bags. If you want more in-depth answer sent me a message on my website.
You will need a minimum of 0.665 cubic meters of cement for this walkway. (if 60 lbs per bag, it is 52.1 bags. If 80 lbs per bag, it is 39 bags).
whats in cement
Girls Aloud Girls Aloud did a cover version of it. It was first sung by Aerosmith, then Run DMC and Aerosmith.
There is no easy way to repair asbestos-cement pipe. If damaged, it should be removed and replaced.
Walk This Way is an American rock song. It was by Aerosmith and is classified as hard rock. It has also had many cover versions, which have ranged in style, including parodies, pop and rap, although the covers are also still mainly rock.
i am paving drive way with Boston city paves i want Portland cement type 11 mixed with sand and additive. thank you
easiest way is to core drill and use pour stone to cement it.
Oh, dude, walking 600 meters? That's like, what, a stroll in the park? I mean, if you're taking your time and enjoying the scenery, it might take you like 6-8 minutes tops. But hey, don't stress about it, just take your time and enjoy the walk!
they walk the way we do
Walk This Way was created on -19-02-01.
Cement is used for various construction projects. Basically all of the modern building foundations are made of cement in one way or the other. There variations as to the kinds of cement but they are basically all meant for similar things. Sidewalks and pavements and certain sports courtyards are made from cement.
did you mean "Walk this Way"? Walk this Way was originally done by Aerosmith, and then remade in the '80s with help from Run DMC.
