CONCRETE MIX DESIGNS-SCREEN ANALYSIS- TERMINOLOGY

The following information has been prepared to assist in the selection of concrete mix designs in certain areas where the use of concrete pumps is a new industry.

The result of years of experience by many concrete pump users and aggregate suppliers has proven the importance of certain requirements necessary to successful concrete pumping. The strength and quality of the concrete is relative to the cement/water ratio and the type of gradation of the aggregates used.

Special emphasis is given to the gradation of the fine aggregates, coarse aggregates sand and used in all pump mixes. Generally speaking, if the screen analysis of the local sand and rock conform to the A.S.T.M. specifications shown on Pages and 13 and the proper ratio of sand and rock are used in the mix, you can expect a pumpable mix.

If difficulty is experienced in pumping the mixes shown on Pages 11 and 12, consult your local aggregate supplier with this information and make the necessary adjustments.

CONCRETE MIX INFORMATION

DEFINITIONS

ONE SACK CEMENT (U.S.)-94lbs. (42.58 KG)

S.S.D.-Saturated Surface Dry: Meaning sand particles may be saturated with moisture but there is no free water on the surface.

OVEN DRY-meaning all the moisture is removed from the sand particle.

SLUMP-a measure of moisture consistency.

W/C SAND-washed concrete sand.

#4 GRAVEL or ROCK-3/8” PEA GRAVEL (1/2” MINUS)

#3 GRAVEL or ROCK-3/4” rock (1” minus)

POZZOLITH-Master Builders Admixture -(Pozz)

P.S.I.-compressive strength (Pounds per Square Inch)

DEFICIENCIES IN SIEVE ANALYSIS of AGGREGATES

The uniform gradation of sand and aggregate in the concrete mix is extremely important in all pumping operations. It is highly possible that the lack of certain sieve sizes may prevent pumpability. In some areas it may be necessary to make up these deficiencies by the addition of “blending sands” to the local sand.

GENERAL RULE-supplement to improve pumpability.

FLY ASH-use up to 15% of cement weight.

POZZOLIN-use up to 13% of cement weight.
