Where a retaining wall is constructed at the toe of the slope, the height if the slope shall be measured from the top of the retained earth behind the wall to the top of. (A lesser slope is usually acceptable for paved areas because hard surfaces like concrete or asphalt naturally conduct water away from the foundation much more efficiently than a porous surface like a mulch bed). You don't mention how steep it is, how much rise you need, or what you are using it for. Two key measurements determine the pitch of a concrete surface: the surface length and the change in height over the length. For a good concrete mix, aggregates need to be clean, hard, strong particles free of absorbed chemicals or coatings of clay and other fine materials that could cause the deterioration of concrete. 30- to 45-degree slope--1- to 3-inch slump; more than 45-degree slope--double forming may be considered for concrete thickness of about 6 inches or more [or shotcrete should be used] "Lightweight concrete of a given workability does not slump as much as normal-weight concrete due to the lighter weight of the aggregate.
