▎ 摘  要

NOVELTY - The method involves obtaining (S101) the raw material of the concrete. The fine aggregate is weighed according to predetermined proportion, fly ash, cement, mixed fiber, coarse aggregate, gypsum, graphene oxide, water reducing agent. The raw material is used (S102) after cooling to combine the proportion data of each raw material to configure the concrete. The prepared concrete is divided into several areas (S103), and a temperature sensor and a pressure sensor are preset in each area. The cooling pipeline is paved (S104) based on the measured temperature of each area concrete. The proportion data of each raw material is combined. The water is added to the graphene oxide after cooling, the temperature is raised to 75-90 degrees C, ultrasonically dispersion is performed for 30-45 minutes at ultrasonic frequency of 20-100 kHz in the ultrasonic machine. The poured concrete is secondary fed and vibrated (S105). The paved cooling pipeline for cooling is used (S106). USE - Rapid casting and temperature control method for large volume concrete. ADVANTAGE - The method can uniformly improve the temperature of the concrete, improve the effectiveness of the temperature control, and avoid crack. DESCRIPTION OF DRAWING(S) - The drawing shows a flowchart illustrating the rapid casting and temperature control method for large volume concrete.
