Results of thermogravimetric tests on hardened cement pastes containing fly ash are reported. Ashes derived from subbituminous and lignite coal were used at replacement levels of 30~c and 50~ by weight.

## Disagreement exists in the literature as to whether or not fly ash accelerates or retards the early hydration of fly-ash blended cements. As an outgrowth of this controversy the effects of two fly ashes, a Class C and a Class Fj their leachates and leached fly ash residues upon the first 24 ho

This paper considers the sulfate corrosion of Portland cement-pure and blended with 30 wt% of fly ash. As raw materials, three kinds of Portland cements, with different content of GA (5.45-l 1.84 wt%), were applied. Fly ash was added so as to decrease the GA content (to 3.82-8.29 v&Oh). The test sam

Blended cement pastes made of Portland cement and fine sand (known in Egypt as El-Karnak cement) were made using a water-cement ratio of 0.25 by weight. Three pastes containing admixture (water-soluble condensates) were also prepared using a water-cement ratio of 0.25 and condensate (superplasticize
