Evaluation of Fly Ash in Water Reduced Paving Mixtures;MLR-84-07, June 1985 [PDF]
, 1985 Fly ash was used to replace 15% of the cement in C3WR and C6WR concrete paving mixes containing ASTM C494 Type A water reducin9 admixtures. Two Class C ashes and one Class F ash from Iowa approved sources were examined in each mix.

Journal of Applied Polymer Science, Volume 143, Issue 39, October 15, 2026.This work explores the use of various fillers, including eggshell powder, feather meal, peanut hulls, and sawdust to reinforce a base binder GFS90 (comprised of 90 wt.% sulfur, 5 wt.% chicken fat, and 5 wt.% sunflower oil). The resulting composites showed impressive compressive strengths ranging from 15.3 to 36.2 MPa, making them a potential ...

Optimization of Soil Stabilization with Class C Fly Ash; HR-260 , January 1987 [PDF]
, 1987 Previous Iowa DOT sponsored research has shown that some Class C fly ashes are ementitious (because calcium is combined as calcium aluminates) while other Class C ashes containing similar amounts of elemental calcium are not (1).

Beyond Equilibrium CO Production via Temperature Swing Adsorption‐Assisted Reverse Water–Gas Shift
ChemCatChem, Volume 18, Issue 18, 28 September 2026.SE‐RWGS over a CuO/ZnO/Al2O3 catalyst mixed with Zeolite 3A adsorbent is investigated experimentally in a fixed‐bed reactor. CO2 conversion and CO yield exceed 80% during the sorption‐active phase, far surpassing the thermodynamic equilibrium limit.

Evaluation of porous concrete leachate to improve water quality
Journal of Environmental Quality, Volume 55, Issue 5, September/October 2026.Abstract Porous concrete is increasingly explored as a multifunctional material for water quality improvement, stormwater management, and emerging agricultural applications. However, uncertainties remain regarding nutrient and trace metal leaching, particularly for freshly cast concrete. This study investigated the time‐dependent leaching behavior of a

A Study of Ferrospheres in the Coal Fly Ash
Open Journal of Applied Sciences, 2019 Coal fly ash is an industrial by-product, produced from coal combustion in thermal power plants. It is the most complex anthropogenic materials, which consists of combination of minerals originated from different sources. Coal fly ash and its byproduct has become an environmental concern over the World.

Land Degradation &Development, Volume 37, Issue 15, Page 11613-11627, September 2026.ABSTRACT Coal mining severely degrades soil profiles and ecosystem functions, highlighting the need for effective reclamation. Reconstructing soil profiles with industrial solid wastes offers a promising waste‐to‐resource approach, but the ecological effects of different engineered key‐layer materials remain unclear.
