Cavity walls are the double-wall, consisting of two separate leaves of wall between which there is the presence of a thin air gap or filled by insulating material connected together with the wall tiles. The cavity intercepts movement of moisture, sound and heat from the outer leaf to the inner leaf. They can be of …

Estimation of Earth work excavation in civil engineering is the process of calculations of expected quantity required, amount of work to be done, the number of worker and equipment required and total expenditure cost to complete any project. Different types of quantities are required to be estimated accordingly to their types of work. For example, …

The pipeline is the arrangement of the closed conduit to flow and transport any fluid (both gas and liquid) from one destined place to another with a minimum amount of loss. Different types of pipelines are used for a different purpose. Both pressure flow and non-pressurized flow can be achieved in pipelines. The pipe is …

What is Concrete Topping ? Concrete topping is the process of overlaying (resurfacing) the hard, non-abrasive, structurally tough layer of concrete over any existing surface. The old surface may be worn out or structurally not suitable for the special purpose; such as installing pieces of machinery and big equipment causing impacts and vibration at workshop, …

Concrete has the unique property of the plastic behaviour at its fresh or green state and then hardens to the rigid structure within a few intervals of time. This property of concrete helps to cast it into a different shape. It also allows us to provide a different kind of surface texture with help of …

What is Box girder bridges? Girders are the large section beams above which the slab(deck) rests. They are generally adopted for the bridges. The Box Girder are hollow channel-shaped beams containing two (or more) side webs and two flanges. The box shape can be either trapezoidal or rectangular. In such girder, one of the flanges …

Elasticity, stress and strain When the external force is applied to the material body, it processes for change in shape and size. If the force is not too sufficiently large then the material body returns to its original state when force is removed. T his property of the material body due to which it returns …

What is a Spillway? Definition Dams are generally constructed to store water of the channel so that it can be used for future work like irrigation, electricity, and mostly for flood control. In some case, dam get overflow of water which may damage the whole design and structure if we do not discharge excess water …

Introduction Retaining walls are built in order to retain the soil masses located at suddenly abruptly changing elevation and provide lateral confinement. The retain mass on another side of the wall exerts lateral force and overturning moment to the constructed wall, and thus the wall is needed to design to encounter such forces and moment …

What is Grout? Grout is quite viscous fluid or slurry obtain by admixing the cementing or binding materials along with required chemicals, a polymer that increases adhesive property and water so that they can be easily pressurized or flow in a gap space and capillaries. Thus they are used in reinforcement techniques where there is …
