Influences of Environment Climate Conditions on Concrete ...

Environment climate conditions are important influencing factors on concrete carbonation rates. Influences of concrete internal microclimate conditions including internal temperature (T) and relative humidity (RH) and external climate conditions including wind speed and wind direction on concrete carbonation rates were studied through laboratory accelerated carbonation experiments.

Influence of Environmental Conditions on Temperature Field ...

The temperature cracking of early-aged concrete is often met by constructors in recent years, because of large temperature difference of core and surface of concrete. Experimental study on temperature field of concrete under different environmental conditions is conducted. Different environmental conditions such as wind speed, formwork removal, sun radiation and conservation are involved.

30/08/2010  Carefully controlled temperatures ensure that the compounds combine, melt, and cool properly to form marble-sized pellets called clinker. After cooling, this clinker is ground into a fine powder and gypsum is added (typically 5% by weight) to aid the setting time, storage, and workability of the cement. The portland cement is then bagged at the plant or sent to precast or ready-mix facilities ...

This process can be initiated without any influence on the environment or with the support of the environment. The increase in the volume of the concrete causes cracking. Generally, the sulfate related stresses are developed in the surface of the concrete referred to as external sulfate attack. It causes by the reaction of the sulfates contained in the groundwater or soil reacting with the ...
