Data for: Performance of Fly ash blended Crushed Sand Concrete

The dataset contains the semi-adiabatic temperature measurement of mass blocks of M50 grade concrete proportioned with (i) ordinary portland cement (OPC) with crushed sand (CS), (ii) OPC with 20% replacement of fly ash and river sand (RS) and (iii) OPC with 20% replacement and CS, designated as CCS, CFRS and CFCS respectively. This dataset also includes cube compressive strength of 200 samples of CFRS & CFCS concretes tested from different batches of field concrete, rapid chloride penetration test (RCPT) results and fines (silt) content variation of CFCS concrete used in a major construction project.

本数据集包含M50等级混凝土大体积块体的半绝热温升测试数据，对应三种配合比方案：(i) 普通硅酸盐水泥（Ordinary Portland Cement, OPC）搭配机制砂（Crushed Sand, CS）；(ii) OPC掺加20%粉煤灰并采用河砂（River Sand, RS）；(iii) OPC掺加20%替代组分并搭配机制砂，上述三种配合比分别命名为CCS、CFRS与CFCS。此外，本数据集还涵盖了取自不同批次现场混凝土的200组CFRS与CFCS混凝土试样的立方体抗压强度测试结果、快速氯离子渗透试验（Rapid Chloride Penetration Test, RCPT）数据，以及某大型建筑工程中所用CFCS混凝土的粉粒（淤泥）含量变化情况。
