A short description of research activities:

a) Development of Alkali Ash Material

In this project, a new type of construction material, called Alkali Ash Material (AAM) concrete, has been developed. AAM contains 40-95% Class F fly ash and is used as cement to bind sand, stone, and fibers creating concrete. AAM concrete has been tested for strength, durability, mechanical properties and, most importantly, economic viability.

AAM concrete is economically and technically suitable for many construction applications. Some properties include rapid strength gain (90% of its ultimate strength in 1 day) and high ultimate strengths (110 Mpa or 16,000 psi in 1 day). AAM’s resistance to chemical degradation by sulfuric (H2SO4), nitric (HNO3), hydrochloric (HCl), and organic acids, makes it superior to Portland cement concrete. AAM is also resistant to freeze-thaw attack based on ASTM C-666 specification.

Immediate applications of AAM material could include use in blocks, pipes, median barriers, sound barriers, and overlaying materials. Eventual markets are high-strength construction products, bridge beams, pre-stressed members, concrete tanks, highway appurtenances, and other concrete products.

b) Removal of Heavy Metals from Contaminated Water.

Contamination of water is a serious problem in the United States. Heavy metals account for 50% of surface and ground water contamination. I am developing an inexpensive, permeable, reactive barrier made of alkali-activated fly ash, called Alkali Ash Material (AAM). This material is capable of reducing heavy metals such as mercury, lead, cadmium, chromium, zinc, cesium and cobalt in water from a concentration of 100 ppm to below the drinking water standards.

To test this material, fly ash was chemically activated with the aid of a gassing agent to achieve the desired permeability of approximately 10 -1 cm/sec. Synthetic solutions of 10 ppm, 100 ppm and 1000 ppm of heavy metals were passed through a column packed with activated fly ash material. The results indicate that activated fly ash is capable of removing heavy metals from the aqueous solution to a level below the drinking water standard

c) Preventing Steel Rebar Corrosion Using Alkali Ash Material (AAM)

Concrete is a construction material that is relatively easy to work with. However, the tensile strength of concrete is very weak in comparison to its compressive strength. Because of the low tensile strength, reinforcing steel bars are placed in regions of tension in a concrete member. This combination of concrete and steel provides a relatively inexpensive and durable material that has become widely used in construction of roadways, bridges ,etc.

A refined metal such as iron or steel has a natural tendency to corrode. The rate of steel corrosion depends on its composition, grain structure, and the presence of entrained stress from fabrication. It also depends on the nature of the surrounding environment, such as the availability of water, oxygen, and ionic species, pH and temperature. AAM concrete has unique chemical properties because the hardened cementitious product is a sodium aluminosilicate hydrate rather than a calcium silicate hydrate. The AAM matrix has low porosity, low permeability, high pH, and creates a layer of silicate on reinforcing steel. The silicate layer inhibits corrosion beyond the effects of elevated pH. The resulting matrix provides a superior protection of steel from corrosion. In addition, AAM is resistant to chemical corrosion. AAM has shown excellent durability in a variety of severe chemical environments including strong mineral acids.

In this project, rebar was coated with AAM and tested for resistance against corrosion. The results were compared with those of uncoated steel and epoxy-coated steel. As the preliminary results indicted, AAM-coated rebar demonstrates a five-fold increase in resistance of corrosion over uncoated steel. Epoxy-coated

rebar performed three times better than AAM-coated rebar against corrosion. However, the performance of damaged epoxy-coated rebar was only 8% of undamaged epoxy-coated rebar.
