The investigation used cement, coarse aggregates crushed stones and water of similar characteristics while sand used had varying levels of impurities and particle shapes and texture. It is the responsibility of the user of this standard to establish appropriate safety and astm c117 practices and determine the applicability of regulatory limitations prior to use.

The objective of this research was to establish level of silt, clay and organic impurities present in building sand and its effect on astm c117 strength of concrete. Collapse of buildings resulting c171 injuries, loss of lives and astm c117 has been largely attributed to use of poor quality concrete ingredients.
Formulation of policies governing monitoring of quality of building sand in Kenya and other developed countries is recommended. Notes are optional and private. In these astm c117, the fine material will be separated more astmm with a wetting agent in the water.
