 · Chromite ore processing residue is the solid waste remaining after aqueous extraction of oxidized chromite ore that is combined with soda ash and kiln roasted at high temperature. Chromium is a trace of metallic element that is found in the earth's crust in concentrated ore deposits, principally as FeCr 2 O 4.

 · Besides preventing valuable natural resources from going to waste, using stone waste from stone processing plants in concrete helps reduce environmental pollution and, therefore, offers a convenient route to sustainable development. The present study aims to use granite waste (GW) in high-strength refractory concrete. Sixteen high-strength refractory …

Although aggregates are most commonly known to be inert filler in concrete, the different properties of aggregate have a large impact on the strength, durability, workability, and economy of concrete. These different properties of aggregate allow designers and contractors the most flexibility to meet their design and construction requirements.

Aggregate is a widely used building material in modern engineering. In general, the aggregate is divided into coarse aggregates and fine aggregates. Specifically, the fine aggregates with a particle size below 5mm are also called sand. The particle size above 5mm is called coarse aggregate, which is often called stone. Camelway has years of experience in producing sand …

70 to 80% of the volume of concrete is aggregate keeping the cost of the concrete low. The selection of an aggregate is determined, in part, by the desired characteristics of the concrete. For example, the density of concrete is determined by the density of the aggregate. Soft, porous aggregates can result in weak concrete with low wear resistance, while using hard …

Aggregate" is a collective term for the mineral materials such as sand, gravel and crushed stone that are used with a binding medium (such as water, bitumen, portland cement, lime, etc.) to form compound materials (such as asphalt concrete and portland cement concrete).
