Limitations of Concrete or Disadvantages of Concrete | 8 Reasons

Though Concrete is one of the most widely used construction materials, there are lot of disadvantages associated with it. Some of these disadvantages of concrete are modified by adding admixtures or modifying the concrete structure and ingredients. Still there are lot of limitations associated with concrete. Major limitations of concrete are listed below. 1. Concrete … Read more

Preloaded Bolts (Pre-tensioned Bolts) | Advantages | Applications

Manual Pretensioning of Preloaded Bolts

Preloaded Bolt Bolts are tightened such that a high tension, usually above yield strength, is developed in the bolts, these are called preloaded bolts. The plates of the connection are thus clamped together and shear transfer between the plates is achieved through friction. Preload is the tension load developed in a fastener while tightening. The … Read more

Ground Anchor (Earth Anchor) | Types | Anchor Length

Earth Anchors after installation - aarsleff

Ground Anchor A Ground Anchor, also known as Earth Anchor, is a structural member which transmits an applied tensile force to capable ground. The tensile force is resisted by shear strength of the surrounding ground. An earth anchor may comprise of following three main components Tension pile Rock bolt Deadman Nowadays, a High strength steel … Read more

Impact Factor | Dynamic Allowance in Design | Causes | Characteristics | Bridge Loads

Impact Factor is considered for Vibration induced by Truck on Bridge

Impact Factor Vehicular Live loads are multiplied with an Impact Factor to accommodate this dynamic effect in the design of bridges. The dynamic loads for moving vehicles are considered Impact in bridge engineering because of the relatively short duration. The magnitude of the impact factor depends on the bridge span, stiffness and surface roughness, and … Read more

Concrete Formwork (Shuttering) Releasing Agents | Type | Functions

Removal of Hardened Concrete Block From Shuttering

Releasing agents are coatings applied on the formwork surface, prior to concreting, in-order to facilitate easy removal the form work or shuttering. If the appearance of the concrete surface is of significance, it is important that care is taken with the finish surface of the shuttering. Finished concrete surface will reflect all the defects on … Read more

6 Crucial Design & Construction Requirements of Formwork (Shuttering)

Formwork The function of formwork (Shuttering) is to hold freshly placed and compacted concrete till it has gained sufficient strength to be self-supporting. It also serves the purpose to produce a concrete member of the required shape, size and the desired finish. 6 Major Design and Construction requirements of Formwork The formwork should be sufficiently … Read more
