Experimental Study on Temperature Data of Mass Concrete Construction in Hot Weather Conditions

Abstract:

Through studying on temperature data of mass concrete poured completely after 20 days, the temperature time-history curves were plotted in different heights section of the raft foundation. Moreover, the characteristic parameters such as solid concrete temperature, temperature difference between inside and outside , also between surface and atmosphere, and its cooling rate were studied. Then by checking cracks of the mass concrete, the most likely period of temperature stress cracks appearing is pointed out. The useful experience data of the mass concrete construction in conditions of hot weather is accumulated, whose concrete strength standard is evaluated by 28d age.
