ACI 363.2R-11 PDF Download

The ACI 363.2R-11 standard provides guidance on the quality control and testing of high-strength concrete (HSC). The use of HSC has become increasingly popular as an alternative to conventional normal-strength concrete in infrastructure systems. This guide offers general information and recommendations based on extensive research and practical applications of HSC worldwide.

The standard acknowledges that HSC can be used to reduce member cross sections, extend span lengths, decrease the number of system members, and enhance system sustainability in concrete structures. It recognizes the importance of quality control and assurance in the production and testing of HSC to ensure that it meets the desired strength and performance requirements.

The guide emphasizes the need for proper material selection, mixture proportioning, and testing procedures to achieve the desired strength and durability of HSC. It provides recommendations on the quality control and testing of constituent materials, including aggregates, cementitious materials, and admixtures. It also discusses the importance of proper curing methods, temperature control, and curing time to optimize the performance and strength development of HSC.
