Fiber reinforced concrete contains fibrous material that enhances structural integrity. In this type of concrete, fibrous materials are distributed uniformly and randomly. This type of concrete is excellent from the perspective of durability and toughness performance of concrete and mortar. Fibers present in the concrete decrease shrinkage cracks, increase strength, increase energy absorption, and decrease … Read more
A huge quantity of concrete is placed in large structures such as dams, canals. the tunnel, bridge, flyover, etc is called mass concrete. For mass concrete, the slump value varies between 25 to 50 mm. Large size aggregates are used for mass concrete. These aggregates provide low slump value and very stiff concrete. Large size … Read more
Stamped concrete is concrete that is patterned or textured to resemble brick, slate, stone, flagstone, tile, wood, and other different patterns and textures. Stamped concrete is a very innovative concept in concrete widely applied for the floor in patios, car porches, driveways, sidewalks, etc. The idea of concrete decoration with stamped concrete adds strength to … Read more
Workability of concrete is the characteristic of freshly mixed concrete which defines the ease and homogeneity with which it can be mixed, transported, placed, compacted, and finished as described by ACI Standard 116R-90 (ACI 1990b). As per ASTM “that property determining the effort needed to manipulate a freshly mixed quantity of concrete with minimum loss … Read more
Polymer Concrete Polymer Concrete is a special type of Concrete that utilized Polymer instead of Lime-type Cement as a binder. In certain circumstances, Polymer is used in addition to Portland cement to make Polymer Cement Concrete (PCC) or Polymer Modified Concrete (PMC). The traditional concrete is puros due to the presence of air voids, water … Read more
Creep in Concrete Elastic and long-term deformation of Concrete under a continuous load is called Creep. Long-term stress alters the shape of the concrete structure and deformation occurs along the direction of applied stress. After the removal of stress, the strain is reduced immediately. The amount of the reduced strain is equal to the elastic … Read more
Shrinkage is an intrinsic characteristic of concrete. The shrinkage in concrete can be characterized as the volume changes observed in concrete because of loss of moisture at various stages due to different reasons. Concrete Shrinkage The loss of moisture content due to Evaporation in concrete is known as the shrinkage of concrete. In the first … Read more
Shotcrete Shotcrete is also known as sprayed concrete. Shotcrete is pneumatically projected or sprayed with the help of a nozzle at high velocity on the prepared surface. The complete system is also called spraycrete. Shotcrete is poured and consolidated at the same time due to the load ejected from the nozzle. Shotcrete can be placed … Read more
Reinforced Cement Concrete in short form called RCC. Most of the building structures are made of either steel or RCC. A normal building structure is made by RCC. It is a very innovative material that resists both tensile forces as well as compressive force. Due to the huge load resisting capacity, it is widely used … Read more
Lintel A Lintel is a type of beam which is placed across the opening of doors, windows, and equipment opening in the wall. The Lintel is a load-bearing structure and it is provided across the width of the window. In the window, the beam provided at the bottom level is known as the Sill. Sill … Read more
