Carbon Fiber Reinforced Polymers- Properties, and Applications
Carbon fiber reinforced polymer (CFRP) is a type of composite materials consist of carbon fiber and polymer. The carbon fiber provides the strength and stiffness while the polymer acts as cohesive matrix to protect and held the fibers together. CFRP ...
5 Monitoring Techniques for Early Strength Gain of Concrete in the Field
Monitoring early strength gain of concrete in the field is crucial task for the success of some construction works like starting critical shoring and reshoring steps which is required during multi-storey building construction and removal of formwork. There are several ...
Requirements of High Performance Concrete
High performance concrete (HPC) is produced in order to meet several requirements which are crucial for the successful construction of buildings in special circumstances. The performance requirements of HPC may involve improvement of concrete placement and compaction without segregation, long-term ...
Applications of Reinforced Concrete
Applications of Reinforced Concrete is mainly due to its versatility, adaptability and resistance to fire and corrosion resulting in negligible maintenance costs.
6 Types of Deleterious Substances in Aggregate
Deleterious materials in aggregate are those substances which detrimentally effect the fresh and hardened properties of concrete for instance strength, workability, and long-term performance of the concrete in which such are used. Deleterious materials and highly undesirable constituents. Organic impurities, ...
Alkali Aggregate Reaction in Concrete – Types, Causes, and Effects
Alkali aggregate reactions (AAR) occur when aggregates in concrete react with the alkali hydroxides in concrete producing a hygroscopic gel which, in the presence of moisture, absorbs water and causes expansion and cracking over a period of many years. This ...
