Determination of field strength of concrete from maturity functions

Abstract

A maturity function valid for the Ethiopian
cement and its equivalent is derived from test
results of strength development of concrete in
relation to temperature and time. Making use
of the maturity function so obtained, the time
· for the development of strength of concrete under
prevailing field temperature is converted to an
· equivalent time under the standard laboratory
temperature of 20°C. The strength (curing time)
of the field concrete is then determined from
the standard laboratory curve of the same concrete
or cement using the respective equivalent time
