The capacity of concrete is reported in psi – pounds per sq inch in US units and in MPa – mega pascals in SI unitsThis is usually called as the characteristic compressive strength of concrete fc/ fck For normal field applications, the concrete strength can vary from 10Mpa to 60 Mpa
containers may not allow to pour into, without possible large voids A fast check on the correct weight is also possible by turning the bucket with up-side down If the weight of the is minimum 80 g/l and does not drop out of the bucket, the consistency of the is correct
Jun 12, 2012· In this paper, we report the results of our investigation on the possibility of producing concrete by using a geopolymer system Class C fly ash was mixed with an alkaline activator solution (a mixture of sodium silicate and NaOH), and was added to the geopolymeric mixture to produce lightweight concrete
