Abstract

Fly ash waste (resulting from coal factories) causes pollution in air and water. However, it can be used as the major component of geopolymer which is a cementing material with a very high compressive strength and low permeability. This research introduces preparing nanolime (NL) mechanically in an innovative technique. This will facilitate the industrial applications on large scale. Nano size will be confirmed by measuring the size distribution using a dynamic light scattering device (DLS). Followed by, formulating and testing geopolymer (GP) mixed with NL as an economic well cement type that results in higher strength and lower permeability at higher temperatures. The final compressive strength (CS) of nanolime-geopolymer (NLGP) was measured using different molarities and ratios of its components in order to compare and evaluate the results. Besides that, the NL concentration increase was studied versus the increase in the CS to explain the effect of NL concentration on GP. In addition, the permeability (k) and density (ῥ), rhyology of different compositions are compared. The results indicate that 12% NLGP led to (CS = 55 MPa, K = 0.011 mD, ῥ =11.7 ppg and highest viscosity curve). The low permeability is very effective for gas wells. Integration calculations proved that the high compressive strength leg to a reduction equals 32/45 for the average fractures width after rupturing. Finally, NLGP can be sold with a competitive price (2000 USD/ton) to achieve profit = 370 %. The novelty is highlighted by introducing the innovative NLGP. 12% NLGP is the recommended product technically and economically. The resulting values of CS, K, ῥ for 12% NLGP are very competitive compared to cement fly ash (CF) and an innovative cement containing manganese tetroxide (MT) mixed with hematite (H).
