What Is Pneumatic Structures? Pneumatic Structures are a special type of structure that is generally characterized by the slightly higher air pressure of internal surroundings. The word ‘Pneumatic’ means structures that are constructed with the support of Air Pneumatic structures were introduced in Building Technology about 40 years ago. The pneumatic structure is a membrane…

What Is a Concrete Vibrator? A concrete vibrator is a machine used for construction purposes in civil projects. concrete vibrators come in a variety of shapes and sizes. Some concrete vibrators are smaller, more efficient, and at battery power, while others are much larger with a primary power source based on electric power lines. Choosing…

Introduction of RQD In Civil engineering, different parameters are used to characterize the Quality of the rocks. Evaluation of the Mechanical Properties of the rocks and Characteristics of rocks is one of the challenging parts of rock engineering. Rock mass has wide applications in the construction of structures, excavation, and tunnels and in maintaining stable…

Introduction to Extra Rapid Hardening Cement Time is one of the most important factors in construction projects. Time is directly connected to the cost of the project. The use of ordinary portland cement in the construction required more time for hardening and removal of Formwork. Whereas the Extra Rapid Hardening cement sets faster and also…

What Is a Retaining Wall? A retaining wall is a design of a structure; it is built when there is a desired change in ground elevation and to resist the lateral pressure of soil that exceeds the repose angle of the soil. At different levels on the two sides supporting soil laterally retaining, walls are…

Introduction of RCC ( Reinforced Cement Concrete) Concrete is a versatile material that is widely used for the construction of structures. RCC’s full form is Reinforced cement concrete. RCC meaning in civil engineering is a composite material that consists of steel and concrete ( which is a mixture of cement sand and aggregate) and is…

Introduction of English Bond & Flemish Bond Various types of bonds in brick masonry used for wall construction are classified depends on bonding style and laying of bricks in walls. The bond pattern used in brick masonry is developed by the mortar filling between two layers of bricks and in grooves when bricks are laid…

What Is Formwork? The construction of a concrete building requires formwork to support the slabs (horizontal formwork) as well as columns and walls (vertical formwork). The terms concrete formwork and concrete form carry the same meaning and are used interchangeably in this book. Formwork is defined as a temporary structure whose purpose is to provide…

Reamed Meaning Reamed is a cutting procedure for which a cutting process creates a very precise hole size. What Is Under-Reamed Pile Foundation? The Under-Reamed Piles Foundation is a response in areas whereby black cotton soil might eventually cause structural instability. In most instances, soils experience volumetric variations due to fluctuations in moisture below the…

What Is Chicken Mesh for Plaster? Chicken wire has specific properties for plastering use. Chicken wire mesh is formed by twisting two adjacent wires at least four times, forming a strong honeycomb mesh structure. So, it has high strength and durability. Using it when plastering effectively prevents the plaster layer from drying out and cracking….
