Flowable Fill - Sika® Lightcrete Liquid

Flowable Fill Admixture

Sika® Lightcrete Liquid is a ready-to-use liquid admixture to produce Controlled Low Strength Material (CLSM), also referred to as flowable fill, controlled density fill (CDF), lean mix backfill, unshrinkable fill or flowable mortar. Sika® Lightcrete Liquid is compatible with all conventional CLSM materials.

• Produces a fluid material with minimal shrinkage or segregation.
• Eliminates the need for compaction of layered backfill.
• Produces very stable air contents.
• Significantly faster and less labor intensive than compacted soil fill.
• Sika® Lightcrete Liquid is compatible with all conventional CLSM materials.
• Sika® Lightcrete Liquid contains no calcium chloride or other corrosive agents.
• Easy to use.

Usage

Sika® Lightcrete Liquid is recommended for use whenever the material for structural fill or backfill is requested. Sika® Lightcrete Liquid is ideal for use in tight or restricted areas where placing and compacting soil or granular fill is difficult or even impossible. Typical CLSM applications are filling voids under existing pavements, buildings or other structures, backfilling narrow trenches, and filling abandoned underground structures such as culverts, pipes, tunnels, storage tanks, wells, sewers, etc.

Application

Application Information

Mixing

Sika® Lightcrete Liquid can be added in the ready mix truck at the concrete plant or at the job site. Adding Sika® Lightcrete Liquid will increase the concrete volume by 20-35 %. Sika® Lightcrete Liquid can be transferred from drum or tote packaging into 1 gallon containers to be added conveniently at the job site.

If Sika® Lightcrete Liquid is added at the concrete plant, it can be added to the concrete during any time of the mixing process; the increase in concrete volume after adding Sika® Lightcrete Liquid should be considered during batching. Sika® Lightcrete Liquid should not be added to dry cementitious materials. After adding Sika® Lightcrete Liquid the concrete should be mixed at agitation speed for at least 75 revolutions or 5 minutes to ensure proper mixing.

Consumption

Recommended Dosage

Dosage rates will vary according to the mix design, materials used, ambient conditions and requirements of a specific project. Sika recommends a dosage rate of 13 fl. oz per cubic yard (0.5 L/m³) of controlled low strength material (CLSM) concrete. The dosage rate can be reduced or increased based on the mix design to meet specific project requirements.
