Types of Retaining Walls

Crib walls are made up of interlocking individual boxes made from timber or pre-cast concrete The boxes are then filled with crushed stone or other coarse granular materials to create a free-draining structure There are two basic types of crib wall - Timber and - Reinforced pre-cast concrete

Uses Benefits and Drawbacks of Fly Ash in Construction

Fly ash can be used as prime material in many cement-based products such as poured concrete concrete block and brick One of the most common uses of fly ash is in Portland cement concrete pavement or PCC pavement Road construction projects using PCC can use a great deal of concrete and substituting fly ash provides significant economic benefits

15 Factors Affecting Durability of Concrete

Quantity of cement used in concrete mix will also be a factor affecting durability of concrete If cement content used is lower than the required then water cement ratio becomes reduced and workability also reduced Adding more water to this mix results in formation capillary voids which will make concrete as permeable material

Types and Causes of Concrete Deterioration

leading cause of deterioration in concrete When steel corrodes the resulting rust occupies a greater volume than the steel This expan-sion creates tensile stresses in the concrete which can eventually cause cracking delamination and spalling (Figs 1 and 2) Steel corrodes because it is not a naturally occurring material

MIT students fortify concrete by adding recycled plastic

Oct 25 2017Concrete is after water the second most widely used material on the planet The manufacturing of concrete generates about 4 5 percent of the world's human-induced carbon dioxide emissions Replacing even a small portion of concrete with irradiated plastic could thus help reduce the cement industry's global carbon footprint

Concrete as a Building Material

If an engineer specifies M30 / 20 concrete he wants M30 concrete with a maximum aggregate size of 20mm He does NOT want concrete with a strength of between 20-30 n/mm2 which is a common misinterpretation in some parts of the world Concrete that is cast in place in its mould is called cast-in-situ concrete
