Abstract: High-strength concrete is a type of concrete with compressive strength greater than 40 MPa (megapascals), which is much higher than the strength of normal concrete. High-strength concrete is often used in construction projects where greater strength is required, such as high-rise buildings, bridges, and other structures that need to withstand heavy loads or harsh environments. The high strength is achieved through the use of high-quality materials and careful proportioning and mixing of the concrete. Higher strength concrete experiences excessive early age cracking due to low water binder ratio. This early age shrinkage cracking directly affects the strength and durability of concrete. This paper discusses a review of methodologies used to assess the early age shrinkage cracks in concrete which will help in further high strength concrete shrinkage cracking study. In this review restrained shrinkage ring test, free shrinkage tests are discussed.
