Journal Article 2023 02 06 Cement production has numerous environmental side effects, and it is desirable to reduce the pollutants during cement production. One way of alleviating cement production pollution is by reducing its consumption. Demand for cement can be reduced by introducing alternative materials with the same benefits but are less detrimental to the environment. A natural substitute for cement in infrastructure civil projects is a pozzolan, which is naturally found and is a side product of some industrial processes. One type of pozzolan that has wide availability in Middle Eastern countries is zeolite. Zeolite has been investigated by previous researchers as a replacement for cement for specific types of civil infrastructure development. However, no previous study has investigated zeolite as a substitute for cement for stabilizing sandy soils under impact loading. The feasibility of replacing a percentage of cement with zeolite for stabilizing the sand soil under impact loads is being assessed. Different percentages of cement are replaced with zeolite, and samples are tested under impact loads. Tests indicate that there is an optimum percentage of replacement at which the soil strength under impact loads shows the greatest increase. The optimal replacement percentage is found to be between 30% to 50%. Any replacement below or above that optimal range would hurt the impact strength of the soil samples. The positive effect at optimum replacement percentages can be attributed to the reaction of Calcium Hydroxide and silicate-aluminum structures. Calcium Hydroxide is generated by cement hydration, and silicate-aluminum structures come from the introduction of zeolite into the mix. dealing with any aspect of engineering from fundamental sciences to applications in engineering systems.
