A study was conducted to investigate the suitability of commonly used materials in Goma, DR Congo for concrete production. The objectives of the study were to characterize the raw materials and determine their optimal use for desired resistances. Idjwi sand used, with a fineness modulus of 2.53 and a sand equivalent of 83, was found to be suitable for concrete production. Volcanic origin gravel was well graded but required consideration for its water absorption coefficient of 13.5%. Nyiragongo and Hima cements met standard requirements. Compression tests were carried out on laboratory specimens made using the Dreux Gorisse method, and material quantification results were used to create a table for 1 m3 of concrete based on desired resistances.
Author Keywords: Compressive strength, Concrete, dosage, Workability.

Abstract
A study was conducted to investigate the suitability of commonly used materials in Goma, DR Congo for concrete production. The objectives of the study were to characterize the raw materials and determine their optimal use for desired resistances. Idjwi sand used, with a fineness modulus of 2.53 and a sand equivalent of 83, was found to be suitable for concrete production. Volcanic origin gravel was well graded but required consideration for its water absorption coefficient of 13.5%. Nyiragongo and Hima cements met standard requirements. Compression tests were carried out on laboratory specimens made using the Dreux Gorisse method, and material quantification results were used to create a table for 1 m3 of concrete based on desired resistances.
