Hot Weather Concrete Construction

Hot Weather Concrete Construction

Concrete applications may be considered hot weather concrete at temperatures ranging from 77 to 95 degrees Fahrenheit depending on the specific application. Precautions should be planned in advance to counter the effects of high temperature well in advance of execution to counter these effects.

Optimization of TemperatureControl Measures for Concrete

Optimization Of Temperaturecontrol Measures For Concrete

Temperature control and crack prevention in sluice pier concrete is a key issue in the early design and construction period. Strong surface insulation may lead to cracks after formwork removal, while weak surface insulation may result in a high crack risk in the early age. The water-cooling measure may also cause severe cracks at a rapid cooling rate.

Cement is a finely ground powder which, when mixed with water, forms a hardening paste of calcium silicate hydrates and calcium aluminate hydrates. Cement is used in mortar to bind together bricks or stones and concrete bulk rock-like building material made from cement, aggregate, sand, and water.

Using Chilled Water or Ice to Slow the Cement Hydration

Using Chilled Water Or Ice To Slow The Cement Hydration

Jul 30, 2018 The maximum reduction in concrete temperature that can be obtained is approximately 10 F. Rule of Thumb 1 For every 1 F drop in concrete temperature desired, the mix water temperature must be reduced by 3.6 F. On a weight basis the mix water has the greatest effect on the final concrete temperature. This stems from its higher specific heat ...
