Circular Prestressing

Circular Prestressing is basically utilized to indicate the prestressing of cicular structures, for example, pipes and tanks where the prestressing wires are twisted in circles. As opposed to this term, “linear prestressing” is utilized to integrate every single other kind of prestressing, where the cables can either be linear or bended, however not twisted in […]

Recycled Aggregate Concrete

For attainment of good grade concrete with the usage of recycled aggregate it is very vital to follow the bare minimum prerequisites as per the needs stated by the relevant Structure Standards. Up to standard characteristics of aggregates are the pivotal features which determines the concrete strength, nonetheless ample amount of mixture proportions and concrete […]

Fire Proof Concrete

At extreme high temperatures which are generally experienced in fires, hydrated cement in concrete slowly gets dried out, returning to water (in reality, steam) and cement. This leads in a lessening of strength and modulus of flexibility (stiffness) of concrete. In a few fires, spalling of concrete happens – parts of concrete loosen up from […]

Reactive Powder Concrete

Reactive power concrete (RPC) is: A composite material of ultra high quality with mechanical properties. Mixture of fiber strengthened, super plasticized, silica rage, bond and quartz sand with low water concrete proportion. Quartz sand utilized rather than normal total. Thus, these lines increments compressive quality. Composition It is made out of comparative modulus of flexibility […]

Durability of concrete

The concrete durability has been defined by American Concrete Institute (ACI) as its resistance to the weathering activities, different chemical attack, scratch and other dilapidation processes and activities. Durability is the capacity to keep going quite a while without huge disintegration. A solid material helps the earth by saving assets and decreasing squanders and the […]

Cement Plastering

The breakdown regularly appears as a dynamic de-holding of the plaster of mortar/cement from the surface of the solid and for the most part begins with the development of little hollow zones. This condition for the most part weakens until the plaster on an entire divider gets to be unbonded and lumps exteriorly. On soffits, […]
