Determining the properties of green laterized concrete with fly ash for sustainable solid waste management

Fly ash is an industrial solid waste that has found application in concrete production for minimization of CO2 emission. The introduction of fly ash into concrete and the replacement of the conventional fine aggregate with laterite can be viewed as an attempt to convert industrial waste material cum...

description Fly ash is an industrial solid waste that has found application in concrete production for minimization of CO2 emission. The introduction of fly ash into concrete and the replacement of the conventional fine aggregate with laterite can be viewed as an attempt to convert industrial waste material cum locally available fine aggregate to a purposeful use. This paper presents the results of a comprehensive experimental investigation on the strength characteristics of green laterized concrete with fly ash. The physical and chemical properties of fly ash and laterite were studied to evaluate its possible influence on both fresh and hardened state of cement and laterized concrete. A total of 120 cubes of 100 mm dimensions were cast and cured in water for 7, 14, 21,28 and 56 d of hydration. The results show that the 28 d density dropped from 2467 kg/m3 to 2300 kg/m3 andthe compressive strength from 21.94 N/mm2 to 15.02 N/mm2 for 20 % of fly ash content with 0 % - 30 % laterite introduced. The compressive strength decrease with increase in laterite content; the strength of the laterized concrete increases as the curing age progresses.
