Mass concrete (MC) is widely used in dam concretes due to their large aggregate grain diameters, low cement dosage, and low hydration temperatures. Monitoring of the hydration temperature and compressive strength is an important consideration during the casting of MC in the field. The purpose of this study is to determine the relationship between the compressive strengths of cylindrical specimens with different maximum aggregate grain diameters (D_max) and different dimensions in MCs used in dam construction and to investigate the usability of the weighted maturity method in determining the compressive strength of dam MC. In this study, the compressive strength transition coefficient (fck ø15 × 30/fck ø25 × 50) of the cylindrical samples with different dimensions in MC was found to be 1.135. It was found that the weight maturity method can be used to estimate concrete strength in dam MC with low hydration temperature.

大体积混凝土中不同形状和尺寸的样品的抗压强度之间的过渡系数和大坝施工中的权重成熟法。

大体积混凝土（MC）由于其大的集料粒径，低水泥用量和低水化温度而广泛用于大坝混凝土。在现场浇铸MC期间，水化温度和抗压强度的监测是重要的考虑因素。这项研究的目的是确定具有不同最大聚集晶粒直径（D _max）的圆柱形试样的抗压强度之间的关系。）和在大坝施工中使用的MC的不同尺寸，并研究加权成熟度方法在确定大坝MC的抗压强度方面的可用性。在这项研究中，MC中不同尺寸的圆柱样品的抗压强度跃迁系数（fckø15×30 / fckø25×50）为1.135。研究发现，在水化温度低的情况下，重量成熟度法可用于估算大坝MC混凝土强度。
