During the last few decades, the construction industry has increased the use of both mineral admixtures such as fly ash and chemical admixtures such as superplasti­cizers. Mineral and chemical admixtures play an important role in changing the physical and chemical properties of the concrete matrix. When both calcium hydroxide (CH) and polycarboxylate type superplasticizers are added to Portland fly ash blended cement, the properties are changed considerably. Hydration of Portland cement blended with 20 wt% fly ash and 5.0 wt% calcium hydroxide in the presence of 0.5 wt% superplasticizer has...
