scope:

ACI 211.1 provides methods for proportioning concrete with slumps greater than 25 mm (1 in.) as measured by ASTM C 143/C 143M. This guide is an extension of ACI 211.1 and addresses the proportioning of concrete having slump in the range of zero to 25 mm (1 in.).

The paired values stated in inch-pound and SI units are the results of conversions that reflect the intended degree of accuracy. Each system is used independently of the other in the examples. Combining values from the two systems may result in nonconformance with this guide.

In addition to the general discussion on proportioning no-slump concrete, this guide includes proportioning procedures for these classes of no-slump concrete: roller-compacted concrete (Appendix 3); roof tiles (Appendix 4); concrete masonry units (CMU) (Appendix 5); and pervious concrete (Appendix 6).
