formed? Q1: B: The specific gravity and absorption test was performed on fine aggregate and the following data were obtained: Mass of SSD sand = 500.0 g Mass of pycnometer with water only = 623.0 g Mass of pycnometer with sand and water= 938.2 g Mass of dry sand = 495.5 g Calculate the specific gravity values (dry bulk, SSD, and apparent) and the absorption of the fine aggregate.
Laboratory specific gravity and absorption tests are run on two coarse aggregate sizes, which have to be blended. The results are as follows: Aggregate A: Buck specific gravity = 2.395; absorption = 4.69% Aggregate B: Buck specific gravity = 2.601; absorption = 0.51% What is the specific gravity of a mixture of 50]% aggregate A and 50% aggregate B by weight?
Determine the suitability of the aggregate, with the gradation tabulated below, for use in Portland cement concrete. Review the grain size distribution to determine if it meets all of the relevant specifications for use in concrete (i.e. gradation limits, fineness modulus and % fines).
