 CompCon should be added to the concrete suppliers standard mix that meets project specifications. On projects without a concrete spec, or a minimum partial spec, it is recommended the concrete slump from water only should be 3” – 5”. If greater plasticity is required, a water reducing agent or a plastiser should be used. CompCon is a cementitious material meaning that in order to maintain the specified W/C ration a small additional amount of water will have to be added to the mix design. CompCon is calculated as part of the cementituous material, i.e. Portland cement 450 lbs/cu.yd + fly ash 60 lbs/cu.yd + CompCon 50 lbs/cu. yd. = total cemetitious of 560 lbs/cu.yd. At a W/C of 0.45, the water content will be 252 lbs/cu. yd. Adding CompCon to a standard concrete mix will not change any of the characteristics of the base concrete mix design. All mix design and test result parameters will remain the same. The concrete will exhibit normal slump loss based upon temperature, mix design, admixtures, and time until placement. CompCon has no affect on air in the concrete. Air entrainment may be controlled using any standard A.E.A. (air entraining agent). CompCon will not affect the setting time of the concrete. Normal set will occur unless influenced by admixtures in use. Normally, there will be a slight increase in strength when CompCon is used at a given W/C and at the appropriate percentages. However, if the dosage rate should approach or be in excess of 50% of the mix design dosage rate there could be a substantial strength loss due to unrestrained expansion. CompCon may be used in mixes with any admixture meeting ASTM C-494. Wet curing should be used for a minimum period of 48 hours, after which time, a curing/sealing material should be applied. As with any and all concrete, a water cure for a period of 7 days is desirable, although not necessary if a sealant, with a moisture retention greater than 90%, is used. Using CompCon will not change any of the concrete characteristics, properties, or test parameters. All concrete supply, delivery, placement, finishing, and curing procedures and techniques remain the same and should be in accordance with ACI recommendations. Concrete produced with CompCon could have as high as a 300% increase in impermeability. At the same W/C as a normal mix, there is an increase of surface abrasion resistance by as much as 60%. CompCon will counter drying-shrinkage, and with proper design and application, will create a “crack-free” concrete. | What is CompCon | Chemistry | Concrete Characteristics | Facts about SCC | CompCon & Floor Slabs | Pre-Stressed | Links | | Return Home | Products | What's New | Our Services | Contact Us | |
