ASTM C1435/C1435M − 14 Standard Practice for Molding Roller-Compacted Concrete in Cylinder Molds Using a Vibrating Hammer

ASTM C1435/C1435M − 14 Standard Practice for Molding Roller-Compacted Concrete in Cylinder Molds Using a Vibrating Hammer

Scope

1.1 This practice2 covers molding cylindrical test specimens from concrete when the standard procedures of

rodding and internal vibration, as described in Practice C31/C31M and Practice C1176/C1176M, are not

practicable. This practice is applicable to freshly-mixed concrete, prepared in the laboratory and the field.

1.2 Freshly-mixed concrete is molded in cylindrical molds using an electric vibrating hammer equipped with a shaft and circular plate.

1.3 The values stated in either SI units or inch-pound units are to be regarded separately as standard.

Within the text, the inch-pound units are shown in brackets.

The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other.

Combining values from the two systems may result in non-conformance with the standard

Significance and Use
4.1 This practice, intended for use in testing rollercompacted concrete, may be applicable to testing other types

of cementitious material such as coarse-grained, soil-cement.

This practice provides standardized requirements for molding stiff to very dry consistency concrete mixtures

commonly used in roller compacted concrete construction.

This practice is used instead of rodding or internal vibration, which cannot properly consolidate concrete of this

consistency.
