Abstract
This study aims to assess the production of cellular micro-concrete, consisting of quarry dust, calcareous fly ash, cement, and aluminum powder as aerating agent. The proposed mixture design methodology is based on a Box–Behnken fractional factorial experimental design. Testing of specimens included compressive and flexural strength, density, water absorption, and thermal conductivity measurements. Results indicate that density is a characteristic property which determines all the measured properties. Aerating agent to cement and fly ash ratio has the strongest effect on all the measured properties. The developed methodology is a valuable tool for the production of cellular micro-concrete with predetermined properties by utilizing large amounts of quarry dust.
Highlights
Aggregate quarrying operations such as crushing, sieving, etc., are used to produce large quantities of fine by-products (
Analysis of the cellular micro-concrete (CMC) pore structure was beyond the scope of this study
The aerating agent to cement and fly ash ratio has a significant effect on the density of the hardened specimens, which is a physical property of great importance since, as already mentioned above, it strongly affects all the measured properties
Summary
Aggregate quarrying operations such as crushing, sieving, etc., are used to produce large quantities of fine by-products (
