Paving blocks are today a popular paving solution for urban surfaces. Considering the wide variety of products currently on the market, it is possible to build pavements that differ in terms of functionality, bearing capacity, skid resistance, visual impact, and aesthetic integration with the surrounding landscape. Interlocking concrete paving block is the most common construction technology .
The aim of this work was to study the use of coal waste to produce concrete paving blocks. The methodology considered the following steps: sampling of a coal mining waste; gravity separation of the fraction with specific gravity between 2.4 and 2.8; comminution of the material and particle size analysis; technological characterization of the material and the production of concrete paving blocks.

Building materials, such as concrete, are the most widely produced materials in the world, and the utilization of waste materials as concrete ingredients is being strongly promoted . In the last few decades, the use of various by-products and waste materials has .
produce concrete paving blocks: for example, gasifica- tion residues , crushed clay bricks , and ceramic tile production wastes . Thus, the aim of this work was to study the use of coal waste as fine aggregates to produce concrete blocks for paving. The article briefly evaluates the main technical.
The effects of recycled aggregate replacing levels and cement dosage were analyzed based on compaction test. The results showed that the use of 100% recycled concrete aggregates increased the optimum moisture content and decreased the maximum dry density of base course materials compared to those of natural base materials.
This crushed stone packs extremely well, making it a great driveway material or base for concrete pavers and retaining walls. It is light to dark gray in color and, unlike crushed washed limestone, it contains fines, which help bind the mixture together, making it a concrete-like finished product.
application of coarse recycled concrete aggregate, as the component materials in the con-crete mixtures, it is possible to produce structural concrete that can be satisfactory and even with high quality, which primarily depends on the characteristics of crushed demolished concrete.
The graphite tailing causes serious environmental pollution, and the pollution problem becomes worse and worse with the increase in graphite demands. This paper focuses on the graphite tailing concrete, which can alleviate the environment problem through utilizing graphite tailings. With the orthogonal experimental design, 16 groups of specimens were designed to investigate the compressive .
