ACI 305.1-14 (R2020) (IN-LB) PDF Download

ACI 305.1-14 (R2020) (IN-LB) is a standard specification for hot weather concreting. It provides requirements that can be applied to any construction project involving hot weather concreting. This specification can be cited in the project specification to ensure that appropriate measures are taken for concreting under hot weather conditions.

The standard includes checklists that assist the architect/engineer in supplementing the provisions of the specification. These checklists help in designating or specifying customized project requirements based on the specific conditions of the project.

The specification covers various aspects of hot weather concreting, including production preparations, delivery, placement, finishing, bleed-water evaporation, curing, and concrete protection. It provides guidelines for conducting a preplacement conference, determining concrete mixture proportions, setting maximum allowable concrete temperature, measuring the rate of surface evaporation, implementing evaporation control measures, and accepting a concrete mixture based on field experience or preconstruction testing.
