Shrinkage Reducing Concrete Admixture: Mechanism, and Applications
Shrinkage-reducing concrete admixture promote expansion of the concrete at about the same volume that normal drying shrinkage is contracting it. The net change in length of the hardened concrete is small enough to prevent shrinkage cracks. Shrinkage reducing concrete mixture ...
Reinforcement Repair: Methods, and Procedures
Repair of corroded or deteriorated steel reinforcement and prestressing stands is one of the techniques by which deteriorated structural elements are rehabilitated to regain its original load carrying capacity. Corrosion of reinforcements is frequent due to chemical attacks, fire, and ...
Water-reducing Set-retarding Admixtures: Affects, and Applications
Water-reducing and set-retarding admixtures are chemicals that slow down the initial reaction between cement and water by reducing the rate of water penetration to the cement and slowing down the growth of the hydration products. As a result, concrete stays ...
20 Advantages of High Performance Concrete in Design and Construction
There are several advantages of high performance concrete (HPC) application in building construction which are not achievable using conventional concrete. The strength, durability, resistance to chemical attack, and workability of high performance concrete are high. So, high performance concrete is ...
Applications and Importance of Non-destructive Tests on Concrete
Non-destructive tests (NDT) are widely used and play an important role in engineering projects including newly constructed and existing structures. For new structures, applications are mainly quality control or the resolution of doubts about the quality of materials or construction. ...
Applications of Rice Husk Ash in Building Constructions
Rice husk ash (RHA) plays two roles in concrete constructions. The first role is using rice husk as a substitute for Portland cement which leads to the reduction of the cost of concrete, and the other role is as an ...
Pigments for Concrete: Types, Purposes, and Influences
Pigments are fine dry powder or slurry or aqueous suspension that added to the concrete ingredients to produce colors, other than the normal grey color. It is added during batching as a liquid or finely divided colored inert powder. Pigments ...
