"ANTI-HYDRO"-NCR is a set-retarding, non-chloride solution of organic and inorganic chemicals that reacts with portland cement to produce more complete hydration. Water requirements, bleed water, capillaries and shrinkage are reduced. The increased hydration provides internal curing and a much denser, harder and tougher cement paste that binds the aggregates together. "ANTI- HYDRO"-NCR increases the early and ultimate strength of concrete. These combined reactions produce impermeable concrete that is hard and non-dusting. "ANTI-HYDRO-NCR is suitable for use with potable water and is compatible with subsequent finishes

Joint Details:
A complete water Proofing System Particular Attention to Join Details.
Control Joint Spacing Should be as Recommended in ACI Standard 302-3.2.5, Concrete Flaor and Slab Construction.
Mixing
The mix shall consist of Type-1/Type-2 portland cement, clean well graded, fine and coarse aggregates, conforming to ASTM C 33, designed for maximum strength with a minimum of 3,000-psi ‘compressive strength. Each cubic yard shall contain a minimum af 526 pounds (5.6 bags) of Type-1/Type-2 portland cement and 1% gallons of “Awn-Hyono”” and a water/cement ratio (w/c) between 0.44 and 0.56 and not more than 35 gallons of total liquid. Maximum slump shall be 4”
Mix designs incorparating pozzolans will allow portland cement substitution as follows:
GGBF Slag - 40% maximum
Fly ash - Type C - 30% maximum
Fly ash - Type F - 20% maximum
When substituting pazzolans (p), adjustment shall be made for water demand, yield and water/cement ratio-w/{c+p). Aun-Hyo20%" shall be added with mixing water or to the concrete while partially mixed and mixed fora minimum 1 minute per cubic yard. Addition of "AuriHyona®™” shall be at the jobsite. Where greater plasticity or slump is required, adc « (lick on me Spec.4-8) instead of water. Donor retemper the mix.
Installations:
Placing Concrete
All concrete shall be properly vibrated or consolidated and wood spreaders must be removed as the concrete rises in the forms. Whenever possible, concrete shall be placed continuously until the placement is completed. Construction joints shall be keyed with a2” x 4” key, When placing Is about to be resumed, the joint shall be thoroughly cleaned and treated with a “Ari-Hyono™ Slush Coat composed of 1 part “Ann-Hyoro®", 3 parts water and sufficient Type-t/Type-2 portland cement to form.a thick, creamy mixture Concrete shall be placed before the “Ant-HvbRO™ Slush Coat dries, Refer to ACI. 304R, Chapter 5.4 Placing Concrete
Wall Finishing
After the forms are removed, all ties or spreaders shall be cut back on both wall faces to a depth of approximately 116". Any cracks or oneycombed concrete shall be cut back to sound concrete. These areas shall be treated with “Avn-HyoRo™” Slush Coat, then filled with a mortar consisting of 1 part Type-1/Type-2 portland cement and 2 parts sand, mixed with a solution of 1 part “Ai-HyoRo™ to 10 parts water. All parts are measured by volume.- Precautions
Installation
No concrete shall be placed on wet or soggy ground without first laying and compacting a bed of broken stone or gravel of adequate thickness to prevent the mud from mixing with the concrete, A pump of sufficient capacity to keep water below the poured concrete shall be operated continuously during the placement and for at least 24 hours thereafter. The excavated area must be so prepared that the water will easily drain to the pump without washing cement out of te newly placed concrete.
If saw cutting is required, then apply as soon 8 work is completea, ana wnen the area is clean and dry, apply masking tape over all saw cuts to keep dirt and debris out. Wait 28 days for sufficient vapor reduction and fill all saw cuts with eitherRefer to ACI 402-9.10.
“"Anti-Hydro" conforms to the requirements of ACI 318-4.4.1 and ACI 318-3.6.3. “Ani-Hyowo™, when tested following ASTM C 876-91, exhibited no corrosion. However, Do NOT use “Anti Hydro™ in pre-stress or posttension applications or where chlorides are not acceptable.
Testing for set time is recommended before use as a result of recent globalization of cement sources.
For ambient and substrate temperatures in excess of 80°F, use In place of “Anti-Hydro™ Where job specifications reauire.
Water Pressure
In dealing with any structure subject to hydrostatic pressure, careful consideration must be given to the design of the members. Thickness and reinforcing must be capable of withstanding maximum potential heads, Possible flotation should be checked,
Curing Under Adverse Conditions
concrete slabs are to be placed at temperatures over 80°F, in the direct rays of the sun, or exposed to drying winds, care should be taken to prevent water loss. Dampen sub-base, erect wind barriers, finish concrete nramotly, and start curing, immediately by the use of water Curing, of sheet materials. Continue curing for a minimum of 7 days.
7 days.
