2020-6-30Fresh concrete is prepared for various percentage replacements in concrete grade of M30 and their workability is analysed. The replacement is done at the rate of 0 to 15 in the increment of 5. Various cubes are casted by replacing river sand with cast iron slag in concrete and compressive strength is determined after 7 and 28 days of curing.

2020-7-1The research covered the manufacture of concrete using hand fed concrete mixer fed up to a reasonable capacity of 35 to 45 percent of gross drum volume, ASTM, 1978 . Batches were mixed for 2 minutes in accordance with Indian Standard IS 456, 2000, with 20 seconds charging intervals. Same batch size was used for each individual mixing sequence.

AbstractThe main goal of the presented research was to verify the possibility of obtaining ecological self-compacting concrete of low hardening temperature, containing different types of cements with calcareous fly ash W as main component and the influence of these cements on basic properties of fresh and hardened concrete. Cements CEM II containing calcareous fly ash W make it possible to.
