High-volume fly ash mortar is considered a "green" material, a sustainable development solution for the construction industry, in which the fly ash replacement Portland cement content is over 50%. However, this material has the major disadvantage of slow strength development, especially at an early age, which limits its applicability.

The results identified that fly ash could be primarily considered as hazardous waste with 5/14 heavy metal parameters exceed the limit from 1.7 to 9.5 times and needs to be collected and treated properly. This result is also quite similar to the studies that have been done in China, the US or Viet Nam. Thus, SEM/EDX method could be used for analyzing heavy metal components in fly ash samples of solid waste treatment plants.

The main objective of this paper is to use the data-driven approach to predict and study the factors affecting the compressive strength of steel fiber concrete. Therefore, six machine learning (ML) models were evaluated against a database of 166 samples and ten input variables, including Cement content, Water content, Silica fume content, Steel fiber content, Coarse aggregate content, Sand content, Superplasticizer content, Fiber diameter, Fiber length, Fly ash content.

The objective of this study was to determine physicochemical properties (color, moisture, ash, pH, free acidity, HMF, reducing sugars, sucrose and electrical conductivity) of honey produced in Chena district, Southwestern Ethiopia. Nine (9) honey samples each of 0.5 to 1kg were obtained from Chena district. Moisture and ash content were determined by AOAC method.
