Effects of marble, timber, and glass powder as partial replacements for cement
Abstract
Waste materials, such as glass, marble, and timber, are pressing environmental problems worldwide, and their environmental impact can be best overcome by reusing them. This research mainly aims to determine the impact of using waste materials, such as crushed glass, crushed marble, and burned wood in powder form, as partial replacements for cement on the compressive strength of concrete. Mechanical properties (e.g., compressive strength) and physical properties (e.g., workability and unit weight) were investigated. The powdered waste materials (after passing through sieve #200) were partially replaced with cement by ratios of 10%, 20%, and 30%. Compressive strength was tested on the 7th, 28th, and 56th days. Results showed that workability decreased as the partial replacement level of glass powder, marble powder, and timber ash increased. The results also showed a decrease in the compressive strength of concrete when the replacement level was increased from 10% to 30% for each waste material.
