A cement accelerator is an admixture for the use in concrete, mortar, rendering or screeds. The addition of an accelerator speeds the setting time and thus cure time starts earlier. [ 1 ] This allows concrete to be placed in winter with reduced risk of frost damage. [ 2 ]
Further south, on June 19, 20 and 21, Toronto experienced its first official early season heat wave (In Canada, a heat wave is defined as three or more consecutive days with temperatures at or above 32 °C (89.6 °F)), with temperatures ranging between 33.4 °C (92.1 °F) and 34.5 °C (94.1 °F) and the minimum temperature on June 20 not ...
The curing of concrete when it continues to harden after its initial setting and progressively develops its mechanical strength is a critical phase to avoid unwanted cracks in concrete. Depending on the temperature (summer or winter conditions) and thus on the cement hydration kinetics controlling the setting and hardening rate of concrete ...
Climate change in Indiana encompasses the effects of climate change, attributed to man-made increases in atmospheric carbon dioxide, in the U.S. state of Indiana. According to the United States Environmental Protection Agency, "Indiana's climate is changing. Most of the state has warmed about one degree (F) in the 20th century.

Daily high temperatures range from 70 to 80 °F (21 to 27 °C) in the summer to 50 to 65 °F (10 to 16 °C) in winter, with low temperatures from the 60 °F (16 °C)s in summer to the mid 40s F in winter. [citation needed] Like most Mediterranean climates, much of coastal California has a wet winter and dry summer. Early summers can often bring ...
A humid subtropical climate is a subtropical-temperate climate type, characterized by long and hot summers, and cool to mild winters. These climates normally lie on the southeast side of all continents (except Antarctica), generally between latitudes 25° and 40° and are located poleward from adjacent tropical climates, and equatorward from either humid continental (in North America and Asia ...
