Civil Engineering Horizon - application of retarding admixture in hot weather by S K Ahmad

Concreting in hot weather is a challenge to the construction industry. On the basis of the results obtained in this study there is a clear indication of improvement in the properties of fresh and hardened concrete under hot weather conditions. This study provides a basis for producing economical concrete mixes with a high workability, high strength and low water-cement ratio. The addition of Pozzolith will also reduce the water required for the curing of concrete. The retardation of the initial setting will play an important role in placing the concrete as well as the transport of concrete from the ready-mix plant to the construction site. There will be great saving of precious potable water, which is in high demand in countries with high temperatures for most of the year. It will help to prevent the cold joints. It can be predicted that the chances of corrosion will also be reduced, as the water retained in the core will be small.
