Types of Distresses in Concrete Pavements and their Causes
There are various types of distresses in concrete pavements which may cause its failure. These distress in pavements and their details are discussed. Types of Distresses in Concrete Pavements and their Causes Following are the different types of distresses in ...
Requirement for Detailing of Reinforcements in Concrete Structures
Reinforced concrete is a composite material, hence a proper bond between the two materials – concrete and reinforcement is the first requirement. A minimum length of reinforcing bar is needed to develop the full bond strength between concrete and steel. ...
Preplaced Aggregate Concrete – Uses for Concrete Repair
Preplaced aggregate concrete (PAC) is the coarse aggregate densely pre-packed in formwork. PAC is used for densely reinforced concrete and masonry repairs.
Methods of Concreting of Columns, Pedestals and Footings
Proper concreting of reinforced concrete columns, pedestals and footings is needed to ensure desired strength and durability of these structural members. Improper method of concreting may lead to corrosion of steel reinforcement due to pores, cracks in concrete and concrete ...
Ferrocement: Applications and Advantages in Construction
Ferro-cement is a relatively new construction material consists of wire meshes and cement mortar. Applications of Ferro-cements includes housing, marine, agricultural, rural energy, anticorrosive membrane treatment.
Performance of Various Types of Buildings during Earthquake
Performance of various types of buildings during earthquakes such as masonry, reinforced concrete, wooden, mud, steel and composite buildings are discussed.
Sealing of Various Types of Joints in Building Construction
Protection systems of joints include the sealing of cracks, contraction (control) joints, expansion joints, and construction joints. Joint sealants in concrete minimize the intrusion of liquids, solids, or gases, and protect the concrete against damage.
Mix Design of High-Strength Concrete: Methods, Procedure and Example
Mix design of high strength concrete is influenced by properties of cement, sand aggregates & water-cement ratio have compressive strength above 40 MPa. To achieve high strength, it is necessary to use lowest possible water-cement ratio, which invariably affects the ...
Role of Fiber Reinforcement in Concrete
The role of the fiber reinforcement in concrete is to repair cracks that may develop in concrete due to environmental factors such as drying or due to loading conditions. The fiber reinforcement has very little effect on strength of concrete ...
