Disadvantages of Concrete & Limitations. Disadvantages of Concrete are as follows: Concrete has a very low tensile strength and requires the use of reinforcing bars in concrete tensile zone.; Expensive form is required for casting and molding and to hold the concrete in place until it hardens sufficiently.; The low strength per unit of weight of concrete leads to heavy s and is an
Another disadvantage of concrete is its low thermal/thermally conductivity. While concrete is normal/normally used as a layer of fireproofing between walls, it can be bad/badly damaged when exposed to intense heat. The concrete will help to contain the spread of a fire but will become unusable/unusably in the process. Warning.
Concrete is considered as a chemically combined mass where the inert material acts as a filler and the binding materials act as a binder. The most important binding materials are cement and lime. Inert materials used in concrete are termed as aggregates.Most common aggregates are sand, brick chips, stone chips, gravel, shells, etc.The concrete plays a very important role in all branches of

Sep 09, 2017· Concrete is versatile, but it isn't easily repurposed. "That's the fundamental contradiction of concrete: incredibly flexible while you're making something, utterly inflexible once it's made." It's also long-lasting, and will outlive materials like and metal. But that's not necessarily the case for all buildings constructed from concrete.
Work practs. When laying concrete block, have different sizes on hand to avoid cutting or hammering to make them fit. Work in ways that minimize the amount of cement dust released. Where possible, wet-cut rather than dry-cut masonry products. Mix dry cement
Concrete has similar virtues when used as a residential flooring material. It is difficult to damage, and high heels, furniture legs, and pet claws won't scratch the surface. You also don't have to worry about damage from most dropped items. While it is possible to chip or scratch a concrete surface, you have to
Colored cement paste and patching materials help disguise cracks. Environmentally suspect: While concrete itself is an inert, biodegradable material, the process of making cement requires a lot of energy and produces carbon dioxide. Compared to other building materials such as steel, and , concrete
Figure 5.3 shows an example of the changes in CO 2 emissions from the process of producing blended cement. This example the shows effect of the substitution of clinker by granulated slag for a CEM II/B
