摘要：为了研究振动搅拌及水泥温度对混凝土凝结时间的影响，选取不同的搅拌方式（普通搅拌、振动搅拌）和水泥温度（常温、50 ℃、80 ℃）进行了混凝土的凝结时间试验。结果表明：相同搅拌方式下，随着水泥温度的升高，混凝土的凝结时间缩短；相同水泥温度下，振动搅拌混凝土的凝结时间比普通搅拌混凝土的凝结时间更短；当水泥温度在一定范围内时，振动搅拌对混凝土凝结时间的影响占主导作用；而当水泥温度较高（80 ℃）时，水泥温度对混凝土凝结时间的影响占主导作用；相比普通搅拌，振动搅拌可以使混合料颗粒充分分散，水泥颗粒分散均匀，加快水泥的水化速度，从而缩短混凝土的凝结时间。 Abstract: In order to study the effects of vibration mixing and cement temperature on the setting time of concrete, different mixing methods (ordinary mixing, vibration mixing) and cement temperatures (room temperature, 50 ℃, 80 ℃) were selected for concrete setting time tests. The results show that under the same mixing method, the setting time of concrete decreases with the increase of cement temperature. At the same cement temperature, the setting time of vibration mixing concrete is shorter than that of ordinary mixing concrete. When the temperature of cement is within a certain range, the influence of vibration mixing on the setting time of concrete is dominant. When the cement temperature is high (80 ℃), the influence of cement temperature on the setting time of concrete dominates. Compared with ordinary mixing, vibration mixing can fully disperse the particles of the mixture, evenly disperse the cement particles, accelerate the hydration rate of cement, thus shortening the setting time of concrete.
