    mixture of adequate proportion of cement, water and aggregate. Hardening (or) strength of this material is obtained by the chemical action between water and cement. As the time increases the stronger it grows (i.e strength of concrete is directly proportion to its age).The durability, strength, versatility and other characteristics of concrete depends upon the properties and proportion of the gradients in the mix. Strength of concrete is its resistance to rupture on application of load. It is…

    of the crack propagation. The vessels help enhance the fracture toughness and also help reduce the overall weight of the bamboo, thus making it very lightweight. The bamboo reacts to crack propagation, by increasing its fracture toughness as the strength of the crack growth also increases. The fibers within the bamboo contribute to a lot of the fracture toughness it has, as well as the combination of the parenchyma ground and the hollow vessels. Hard biological Materials Many biological…

    This GPC mix has two limitations such as delay in setting time and necessity of heat curing to gain strength. In order to overcome these limitations of GPC mix, 10% of fly ash was replaced by OPC to overcome the limitation necessity of heat curing and 5% of fly ash was replaced by Ground-Granulated Blast-Furnace Slag (GGBS) to overcome the limitation delay…

    Experimental Analysis The experimental work is carried out to evaluate the shear strength of steel fiber reinforced concrete deep beams without stirrups. For this 18 beams are cast. The beams are tested under two-point loading as per IS after 28 days curing. Fiber fraction is varied as 0%, 1.5% and 3%. The shear span-to-depth ratio (a/d ratio) for beams is kept as 0.60 for case-I and 0.74 for case-II. The cube compressive strength is estimated. The experimental results are compared with…

    Large-scale and industrial construction projects require a unique blend of materials, quite different from those used in home construction. One of these is pre-cast concrete components such as stairways, beams, floors and walls. These elements lend structural integrity, fire safety and insulation benefits. For companies that transport these heavy construction materials, great care must be taken to ensure they arrive at their destination in a timely, safe, and efficient manner. Weight Limits…

    Sushil Bhandari (1997) defined vibration as a repeated movement in the normal rest position. The parameters involved with vibration are commonly amplitude or displacement and velocity or acceleration of the ground movement (Visvan, 2005). During demolition operation, vibration is normally caused by the impact of fallen structures or by the use of explosives (BS 6187:2000), which could pose detrimental effects of structural damage of adjacent premises, buried services like gas pipes, disturbance…

    Polymers Lab - IZOD Impact Test of Notched Polymer Introduction The IZOD impact test is a method used to determine the impact resistance of materials. The main objective of this experiment is to measure the impact strength of three specimens’ material by measuring the amount of the energy required to cause the material to fracture, using Avery Denison 6709 IZOD impact tester. Materials and Methods Apparatus: Three specimens with a machined 45° notch (V-Notch) at room temperature…

    1. At Marino Rocks there is a substantially difference between the rock types on the ‘beach’. Some of these are grain size, age, complexion very common rock types that can be found at Marino Rocks include: sandstone and siltstone. Sandstone is a sedimentary rock composed of sand-sized grains of mineral, hence why its called ‘SAND-stone’. It also contains a cementing material that binds the sand grains together. This is in contrast to siltstone, silt is a size term used for material that's…

    different tutor-specified scenarios Concrete is used for foundations as when compressed, concrete can suffer extremely high compressive stresses before any type of cracking of failure occurs which makes it an ideal substance for supporting large masses such as buildings. Concrete will also be less prone to movement. Also concrete can be made in a large variety of strength depending on the required resistance of the foundation by the amount of the sand and gravel used when mixing, the amount of…
