Overall, concrete with 19 mm crushed stone showed improved result in both the tests compared to others. The compressive strength was found as 3142 psi for concrete with 19 mm crushed stone, which was 7.96% more than 14 mm and 4.93% more than 28 mm and the split tensile strength was established as 1920 psi for concrete with 19 mm crushed stone

Crushed stone is the most important raw material for concrete and asphalt production. As a high-volume low-unit-value industry, the crushed stone production sector is highly competitive which implies the necessity to optimise the costs of all of its production operations, i.e. drilling and blasting, secondary breaking, loading, hauling and crushing. In this context, this paper investigates the

This research focused on evaluating the effect of waste glass powder as a partial replacement of crushed stone dust filler in hot mix asphalt. Three hot mix asphalt samples were produced using crushed stone dust of 5%, 6.5%, and 8% as mineral filler with five different bitumen content of 4%, 4.5%, 5%, 5.5%, and 6%, respectively.

Crushed concrete aggregate is used in construction projects such as bridge foundations, soil-cement pavement bases, airport runways, and oil and gas civil construction projects. It is also used for pavements, shoulders, and sidewalks. In addition, it can be used for making structural grade concrete, lean-concrete, and bituminous concrete.

Crushed stone: If you hear the generic “crushed stone” term, it usually refers to stone that has a mixture of stone dust in it. This type of stone is best used for a base when heavy compaction is needed. As a result, it is typically used for the base of concrete and paving projects, foundations of structures, and driveway bases.

Effect of Size. The grading or size distribution of aggregate has a considerable effect on the properties of concrete as it determines the paste requirement for workability of concrete. The paste also affects the cost of the mix as cement is the most expensive component in the mix. Hence, it is required that optimum size of aggregates is used

The Effect of Aggregate Properties on Concrete Concrete is a mixture of cementious material, aggregate, and water. Aggregate is commonly considered inert filler, which accounts for 60 to 80 percent of the volume and 70 to 85 percent of the weight of concrete.

The use of crushed limestone dust may affect the properties of concrete. As per Celik and Marar the inherent property of concrete to flow known as workability decreases with the use of crushed limestone dust. This is due to the presence of finer particles whose specific surface area is high, which absorbs more water and leads to a reduction in slump value.

Abstract. The amount of crushed cement concrete continues to grow every day from the demolition of old structures, causing more pollution. Hence, owing to the increase in environmental awareness and stringent regulations governing the disposal, as set by environmental protection agencies, more effective measures for the handling and disposal of crushed concrete must be implemented.
