Optimization of fly ash particle size distribution for cementitious systems with high compactness
(Elsevier Sci Ltd, 2019)
Compactness is of special importance for aggregates in concrete; however, the particle-size distribution (gradation) of powdery ingredients is commonly disregarded especially for pozzolanic materials such as fly ash. Without ...
Physical and permeability properties of cementitious mortars having fly ash with optimized particle size distribution
(Elsevier Sci Ltd, 2019)
Gradation of powder materials is often avoided in pozzolanic materials, such as fly ash and slag. Without good gradation, powder materials result in high void ratios similar to the case of aggregates and the products ...
