density. The fly ash percentage corresponding to the maxi­ mum density of the A-2-4 silty sand also seemed to coincide with the minimum value of the optimum moisture content. Other mix combinations of cement plus fly ash and lime plus fly ash with the A-3 sand also produced gains in density.

Utilization of MSWI fly ash as partial cement or sand

2019-11-18  The strength of cement substituted mortar decreases with the increase in fly ash amount, whereas the strength increases when the fly ash is blended as sand substitute. A mortar with highest strength (compressive strength = 30.2 Mpa; flexural strength = 7.0 Mpa) was obtained when the sand replacement ratio was 0.75%. The k value (cementing efficiency) of fly ash varied between 0.36 and
