Effect of raw clay type, fineness, water-to-cement ratio and fly ash addition on workability and strength performance of calcined clay – Limestone Portland cements

Workability and strength performance of blended cements with different replacement levels have been investigated for two calcined clay mineral additions (1:1 and 2:1 type) and mixtures with limestone. The effect of fly ash addition and different water-to-cementitious ratios was also evaluated. The results show that the SO3 content of the blended cements, and the ratio of calcined clay to limestone, can be optimized for maximum strength depending...
