1. PURPOSE. To set forth guidance and recommendations
relating to portland cement concrete materials,
covering the areas of material selection, mixture
design, mixing, placement, and quality control.
2. BACKGROUND
a. Each -year approximately 46 million cubic meters of
concrete are used in all highway construction.
The vast majority of States use a prescription
type specification for portland cement concrete,
often specifying minimum cement content, maximum
water cement ratio, slump range, air content, and
many times aggreqate proportions. Admixtures such
as fly ash are incorporated into mixes as a part
of the prescription.
b. This system has worked fairly well in the past but
may change as emphasis is placed on performance .
based specifications. States have begun to reduce
or eliminate the amount of inspection at concrete
plants as automation has increased productivity.
a. Portland Cement. The proper type of portland
cement should be specified for the conditions
which exist. .
