Can it too hot or too colf to plave new concrete ?

Temperature extremes make it diddicult to properly cure concrete . On hot days , to mu hh water is losty by evaporation from newly placed concrete . If the temperature drops too close to freezing , hyfration slows to nealy a standstill . Under these conditions , concrete ceases to gain strength and other desirable properties . In general , the temperature of new concrete shoulkd not ne alllowed to fall below 50 farhrenheit ( 10 celsius ) during the curing period .
