BERYLEX Specifications for Structural Slabs

GENERAL:
All concrete shall contain a minimum of 5.5 sacks of Type 1 Portland cement per cubic yard - assuming standard, aggregates.

PREPARATION OF SUBSTRATE:
Follow established engineering practices. BERYLEX concrete does rot require a plastic underlayment for waterproofing capabilities.

Mix:
All mixes require a minimum of 12 ounces of BERYLEX LIQUID per sack of cement.
General Heavy Duty : 16 - 24 ounces of BERYLEX LIQUID per sack of cement. Do not exceed a 6° slump.
Acid/Alkali Resistance :  24 - 32 ounces,of BERYLEX LIQUID per sack of cement. Do not exceed a 4" slump.

ADDITION OF BERYLEX:

BERYLEX specified at 16 ounces or less per sack of cement may be added at the batch plant. BERYLEX specified at more than 16 ounces per sack of cement usually should be added at the job site.

Batch Plant - BERYLEX may be added directly to the gauging water or placed in solution and metered.

Job Site - Ask for a low slump of about 2 to 3 inches. When batch truck arrives, measure out portion to above quantities to determine your mix design. Stir well, stop the hopper, pour your BERYLEX  LIQUID mix in the hopper. Allow at least five minutes of fast mixing before discharging the concrete.

STRUCTURAL SLABS:

Note: If air-entraining is required we recommend a vinsol-resin. Depending on focal waters, the amount of air-agent required for a given air readout may be reduced from 15% to 30%. BERYLEX does not impart any air - it does enhance the effect of the vinsol-resin.

PLACEMENT:

Follow "Good Concrete Practices." Use minimum steel trowelling.

CURE:

We recommend using one of the following curing methods:
1.  Water cure for as long as practical. We recommend 7 days minimum.
2.  Apply a membrane cure such as a thermo -set acrylic or chlorinated rubber containing 26% solids immediately after final tooling.

Is used to make BETTER concrete - Not to replace cement BERYLEX cannot correct human errors or man failures.
