How to Build A Durable RCC Structure Concrete is an amazing building material, but making it strong and long-lasting involves mastering five crucial elements: site investigation, structural design, material selection and mixing, careful handling, and ongoing maintenance. Let us discuss each 1. Site Investigation: Imagine you’re planning to build something with concrete, even a small … Read more
What is Alkali Aggregate Reaction Alkali-Aggregate Reaction (AAR), also known as Alkali-Silica Reaction (ASR) or Alkali-Carbonate Reaction (ACR), is a chemical reaction that occurs in concrete structures. It involves the interaction between certain components in the concrete mix: Alkalis: Alkalis are compounds found in cement, primarily sodium oxide (Na2O) and potassium oxide (K2O). Aggregates: Aggregates … Read more
From High Strength to High Performance Concrete Durability of concrete is now becoming the major concern for engineers as concrete may deteriorate with time in several ways. The most common durability failures in an outdoor climate are due to reinforcement corrosion or frost attack. In special environments concrete may suffer from chemical attack by various … Read more
Concrete structures which are subjected to freezing and thawing are likely to deteriorate earlier. Structures which are mostly affected under similar climatic conditions due to freezing and thawing are the exposed surfaces of the top 60 cm of walls, piers, parapets, cornices etc. the durability of such structures can be improved by adopting certain weather … Read more
