The Utilization of poorly graded aggregates in concrete mixes, by B. K. Sengupta & F.E Phiri, Zambia Journal of Science and Technology, Vol.2, no.4, October 1997, Pg. 8-16.


ABSTRACT

Properly graded aggregates are not likely to be available in many areas of Zambia and therefore the possibility of utilizing poorly graded aggregates for concrete was investigated. Poorly graded aggregates were used in designing concrete mixes by extrapolating on the mix design data of the American Concrete Institute and, in general, concrete with satisfactory strength and workability was obtained.
