Effect of Different Coarse Aggregate Sizes on the Strength

Effect of Different Coarse Aggregate Sizes on the Strength

The high cost of conventional concrete materials is a major factor affecting housing delivery in developing countries such as Nigeria. Since Nigeria is blessed with abundant locally available materials like laterite, researchers have conducted comprehensive studies on the use of laterite to replace river sand partially or fully in the concrete. However, the works did not consider the optimum ...

Effects of Granite Sourced from Selected Locations in

Aggregates constitute 60 – 80% of total concrete constituents. The characteristics of concrete may be affected by the sources from which the aggregate was obtained. The effects of granite sourced from four selected locations within Ogbomoso, Nigeria; on the fresh and hardened properties of concrete were investigated. The granites were obtained from: Asafa (80 4.681 N and 40 20.781 E), Ola ...

Jul 04, 2015 In addition, crushing strength is also related to porosity, grain size and amount of altered minerals in a rock. A high crushing value indicates a weak, potentially non-durable material (McNally 1998). Thus, the lower the ACV, the stronger the aggregate in terms of its ability to resist crushing.

Aggregate crushing was carried out in a Los Angeles drum, in accordance with the requirements of EN 1097-2:2020. The analysis showed that for grits of the 10–14 mm fraction, the lower values of the LA indices were obtained, which allows for obtaining a bigger index of crushing strength than in the case of crushing using the 4–8 mm fraction.
